Here’s the picture: • Theme: I want a modern Business-style theme that loads fast, looks polished on mobile, and can grow with us. • Hosting: We don’t have hosting yet, so please recommend and configure an affordable, secure plan (cPanel or managed WordPress—whichever best suits a small business starting out). • Core pages & structure: Home, About, Services, Blog, Contact and any other essentials you feel add value. • Key functionality: A straightforward contact form, a clean way to list our services, and space for future testimonials. • SEO & speed basics: Permalink structure, caching plugin, ...

I’m setting up a new Survival-only Minecraft world and want it ready to welcome roughly 50-100 players without lag or downtime. Your task is to stand up the server, harden its performance and load in the exact plugins I’ll share once we begin (economy, land-claim, anti-cheat and a few quality-of-life extras). A Paper or other high-performance Spigot fork is preferred, so please configure the JVM flags, view-distance and garbage collection settings that keep the tick rate stable even during peak hours. After installing the plugins, sort out their dependencies, tune every config file, and run stress tests to be sure permissions and features behave as expected. Deliverables • A live, fully configured Survival server running the latest Paper/Spigot build • All r...

I want to roll out a comprehensive corporate training programme on Red Hat OpenShift Virtualization (RHOCPv) with IBM Fusion at its core. The goal is to give my technical teams hands-on mastery of the entire stack—from first-touch installation to day-two operations—while mapping every module to the relevant Red Hat certification path. The course must weave theory with live labs and should comfortably cover: • An introduction to OpenShift Virtualization and how it differs from traditional hypervisors • Clean installation on bare-metal or cloud infrastructure, cluster sizing, storage and network prerequisites • Full VM life-cycle management inside OpenShift, including template design and image catalogues • Automation, GitOps and an “Ops-as-Code...

We are developing 3D printing software called FasiX. The beta version has been released (). I want to move it forward on three fronts at once: refresh the user interface so it feels modern and intuitive, introduce a handful of well-scoped new features that users have been requesting, and tighten up performance wherever the current code base allows. Here is what I need from you: • User-interface overhaul – update existing Qt widgets/QML screens for a cleaner, more consistent look and smoother workflow. • Feature extensions – design and integrate the new modules we discuss, wiring them cleanly into the existing architecture. • Performance tuning – profile the code (Valgrind, Qt Creator, or your preferred tools) and apply optimisations without breaking c...

I need a reliable specialist to help me squeeze more speed out of my Google Android Go phone. System-level apps—especially Settings and Camera—open sluggishly, and overall responsiveness feels capped. I’ll supply every relevant detail about the device once we start; what I’m missing is the technical finesse to upgrade or tune it safely and transparently. My research led me to the Firebase Go Admin SDK v4 migration guide, which emphasises trust, clean code, and zero shady shortcuts. I want that same ethos applied here: no questionable rooting, no data grabs, full accountability. Here’s what I’m after: • Diagnose current build and pinpoint performance bottlenecks in the OS layer. • Recommend or apply the safest OTA update, micro-GAPPS packa...

Urgent - support daily 2 hr maximum I’m looking for an Oracle E-Business Suite specialist who can move comfortably between the Financials stack, PL/SQL code, and SOA Suite web-service integrations. My environment is already live, but several custom packages need refactoring, new interfaces have to be exposed, and a few pain points in the Financials workflows call for expert attention. Day-to-day you’ll be reviewing existing PL/SQL, tightening performance where it lags, then wiring the results into Oracle SOA Suite services so external systems can consume or push data without manual intervention. The focus is on the Financials family—think General Ledger, Payables, Receivables, and related reporting—though I may ask you to touch other modules as the work unfolds. ...

My custom-built site has begun to drag: the home page hesitates, product pages crawl, and in truth every click feels sluggish. Tests point toward heavy database queries, but I’m open to any bottleneck you uncover. I need someone to profile the code and queries, trim what isn’t needed, and implement proven fixes—index tuning, query refactoring, smart caching, asset minification, or any other technique that will push the first meaningful paint and full page load comfortably below the two-second mark. Tools such as Lighthouse, GTmetrix, New Relic, or your preferred profiler are welcome so long as the before-and-after metrics are clear. When you’re finished, I want to see: • noticeably faster navigation between pages, • documented changes to the data...

I’m racing against a deadline and need a fresh set of expert eyes on my Power BI file. The core problem is performance—slow, inconsistent results that don’t line up with the business rules I’ve documented. This isn’t limited to a single bar, pie, or line chart; the whole dashboard behaves unpredictably because the underlying logic seems off. Here’s what I’m after: • Walk through the existing DAX measures, calculated columns, and relationships, confirm they match my written rules, then refactor anything that creates bottlenecks. • Trace why query steps in Power Query occasionally inflate refresh times and trim the excess without breaking dependencies. • Test changes end-to-end so the visuals populate quickly and numbers tie out...

My Plex Media Server is up and running on an Nvidia-powered box, yet 4K and even some 1080p videos stall, buffer, or drop quality when I watch on my Smart TV. On mobile I sometimes see the same buffering and lag. I’m looking for someone who can jump in remotely, inspect my current Plex settings, check Nvidia GPU hardware-acceleration, and tune the server so streams reach my TV (and phones) smoothly without constant transcodes or network spikes. You’ll likely need to: • Audit current server configuration, libraries, and storage paths. • Verify Nvidia driver versions and ensure hardware transcoding is enabled correctly in Plex. • Adjust streaming and remote-access parameters for both LAN and external viewing. • Identify network bottlenecks (router, Wi...

Our enterprise workloads run on a tightly-integrated z/OS environment that must stay current, secure, and highly available. I need a seasoned system programmer to take full ownership of installation, upgrade, and ongoing maintenance for the operating system itself as well as its IBM, BMC, and other ISV products. You’ll work directly in SMP/E, prepare and apply maintenance, and keep RACF rulesets aligned with corporate security policy. System initialization, PARMLIB tailoring, JES configuration, Sysplex tuning, and Coupling Facility management are all part of the daily rhythm here, so deep hands-on experience with each is essential. The role also includes: • Building and validating new IODFs through HCD • Managing DFSMS storage classes and policies • Exercis...

My team runs all of our workloads on EC2 and S3 and I want a seasoned AWS engineer to give our current set-up a health check, shore up security, and boost overall performance. The immediate priorities are: • Configuration review – walk through every EC2 instance, S3 bucket, IAM policy and networking rule, calling out weaknesses in security settings and opportunities for performance optimization. • Backup database build – spin up a separate RDS instance that every developer can connect to, then put a clear, manual promotion workflow in place so we can push approved data to production only when we decide. • Hands-on knowledge transfer – my staff are beginners, so I need short, practical training sessions that show them exactly how to navigate the AWS con...

I’m looking for a WordPress specialist to tackle the technical side of my site’s SEO. My main goals are clear: • Improve overall site speed (both front-end and server-side). • Enhance mobile optimisation so every page passes Google’s mobile-friendly test. • Identify and fix crawl errors that are blocking or slowing indexation. * keywords You’ll have access to my Google Analytics account so you can benchmark current performance and validate the gains you make. I expect you to work directly in WordPress, using best-practice techniques such as caching configuration, image compression, code minification, database cleanup, and any lightweight plugin or custom function you deem appropriate.

I’m running an RLHF pipeline and need a sharp, data-driven review of the training code to understand exactly where time and compute are being lost. The sole focus is algorithm efficiency during the model-training stage; everything else in the codebase is stable for now. By surfacing and fixing the slow spots we should see cleaner gradients, faster convergence, and ultimately better decision-making accuracy from the model. What I’ll hand over • A self-contained repository (Python, PyTorch or other language) with reward model, PPO loop, and evaluation scripts • A brief outline of the current hardware limits and expected throughput What I expect back • A profiled breakdown highlighting hotspots in the training loop, dataloaders, and reward computation &bul...

O que pretendo obter: • Correção de erros de sistema, instalação ou remoção de programas problemáticos, limpeza de malware e aplicação de updates pendentes. • Ajuste de configuração de rede (DHCP, DNS, compartilhamento de arquivos e impressoras, perda intermitente de conexão). • R...

I’m looking for an experienced developer to integrate a high-quality AI chat assistant into my WordPress website. The assistant should answer visitor questions about our fitness studio and must support both German and English. I will provide studio-specific content/data so it can be trained and give accurate answers. A key requirement is that the assistant can trigger existing workflows via webhooks and support bookings through Fluent Forms (trial training bookings, memberships/subscriptions, and 10-session packages). These booking processes are already running through Fluent Forms + webhooks and should be connected to the assistant. The chat experience should feel comparable to ChatGPT. Since this is a small business, keeping ongoing costs (API/hosting/usage) as low as possible is...

Our CodeIgniter-based platform is live but a handful of issues are blocking final rollout and I need them resolved right away. What needs attention • Bugs in core flows: login & registration, payment processing, plus several data-display / retrieval screens are throwing intermittent errors. • Performance clean-up: tighten up slow database queries, streamline controller / model code for better efficiency, and shave seconds off overall server response time. • UI polish: a few front-end inconsistencies remain after recent updates and must be brought in line with the existing Bootstrap layout. You’ll be working directly in the existing MVC codebase (PHP, CodeIgniter, MySQL, jQuery). SSH and Git access are ready; as soon as you confirm you can start, I’ll...

My live Magento store, Placewell Retail, needs a skilled developer who can both extend functionality and tune performance without disrupting day-to-day sales. Feature work • Build an advanced search and filtering experience that feels fast and intuitive on desktop and mobile, integrates smoothly with our existing catalog structure, and is compatible with layered navigation. • Introduce personalised product recommendations driven by behavioural data (viewed items, purchase history, etc.) so shoppers see relevant products on the homepage, product pages and cart page. Performance work Right now the site suffers slow page loads, especially on the homepage and individual product pages. I need profiling, code/database clean-up and front-end optimisation to reach consistently qu...

My current web workload sits entirely on EC2 and I’m paying more each month while response times keep slipping. I want fresh eyes on the stack, so the engagement begins with a deep-dive audit: CPU, memory, database behaviour and network flow. Please capture every finding in a detailed, evidence-based report—graphs, screenshots, CloudWatch metrics, the works—so decisions are backed by data, not guesswork. Once the pain points are clear, I’ll need a redesign that balances cost and performance. Feel free to compare alternatives such as Lightsail or a move to managed services, but assume EC2 remains the baseline. The proposal should include an architecture diagram, projected monthly spend, and clear justification for each component. If we proceed to implementation, ...

My custom-built mobile robot is running ROS2 humble; tele-op through a joystick is rock solid, and the hardware stack (motors, encoders, power, safety relays) has already proved itself in long bench tests. Mapping, however, is still an issue. With the current LIDAR-only SLAM setup the occupancy grid comes out distorted, misaligned and visibly warped, so the global planner has nothing reliable to work with. Wheel odometry has been calibrated thoroughly, so I’m leaning toward a problem in the TF chain, bad sensor fusion defaults or simply mis-tuned parameters in our chosen SLAM package (slam_toolbox, though I’m open to cartographer or another option if you see the benefit). I’d like you to step in, trace the root cause, and deliver a clean map that matches the physical env...

My website has started acting up and I need a careful, detail-oriented developer to put it back into shape. Design-wise, several pages now have misaligned elements, overlapping sections, and odd text formatting. The responsive layout is broken on phones and tablets, so content spills off the screen or stacks in the wrong order. Functionality is suffering too: the built-in calendar scheduler no longer saves bookings reliably, and every so often the entire site fails to load, returning a generic error instead of the homepage. Here’s what I need from you: • Audit the front-end code, realign all layout elements, remove overlaps, and tidy typography so the design looks consistent on desktop, tablet, and mobile breakpoints. • Fix the responsiveness issues so the site...

I’m looking for a technically minded partner to dig into an existing production system whose overall responsiveness has begun to lag. The single, clear objective is to raise performance—specifically, to cut processing times so users experience noticeably faster load and execution. Here’s what I need from you: • Profile the current code-base and infrastructure to pinpoint bottlenecks (CPU-heavy loops, excessive database calls, inefficient I/O, etc.). • Propose and implement optimizations—algorithm refactoring, query tuning, appropriate caching, or parallelisation—while keeping existing functionality intact. • Supply before-and-after metrics that prove the speed gains. • Document the key changes so future maintenance remains straightfo...

I need an experienced Azure specialist to provision and configure a fresh Azure SQL Database for my current website code. Right now the site runs on a regular SQL Server instance; I’m unsure whether the existing data must be moved or recreated, so I’ll look to you for guidance on the most reliable path forward. The database’s role is straightforward—solid, fast data storage and retrieval for a live production app. You’ll handle the full setup inside the Azure portal, set the correct performance tier, secure it with firewall rules and proper authentication, generate the connection string, and make sure the site connects without hiccups. If we do identify an existing database worth migrating, you’ll take charge of exporting, importing, and validating the ...

I run a long-standing Private Online private server with a customised C++ codebase. Daily operation now calls for steady, hands-on collaboration to keep everything smooth and fresh. The immediate workload circles around three pillars. First, stubborn bugs need squashing across gameplay mechanics, overall server stability, and even a few UI quirks. Second, I want to enrich the experience with brand-new character skills and other creative additions that will sit naturally beside official content. Finally, consistent performance tuning is essential so the machine keeps handling peak loads without hiccups. The repository is hosted in Git, builds compile in Visual Studio on Windows and deploy to a Linux host that talks to MySQL. Every change should come through clean, well-commented pull requ...
