I need a full-featured, small-scale multi-vendor marketplace built natively for both Android and iOS. The app has to let any store—regardless of product type—open a shop front, list items, and receive orders, so the catalog structure must be flexible enough to cover clothing, electronics, home goods, or anything else vendors decide to sell. User roles the system must recognise: - Buyers - Sellers/Vendors - Admin Core flows include simple account creation, product upload with images and variants, cart and checkout, order tracking, and in-app messaging between buyer and vendor. I will also need an admin console (web or app-based) where I can approve vendors, moderate listings, manage commissions, and view analytics. Payment methods to integrate: - Credit/Debit Cards - Bank Tra...

I have several years’ worth of appraisal data currently scattered across multiple CSV and TXT files. The goal of this project is to collect that raw information, move it into a clean Microsoft Access back-end, and then give me simple, point-and-click ways to work with it every day. Core objectives • Build the Access tables from my existing CSV/TXT files • Design friendly forms so I can review, edit, and manage the records without touching the tables directly • Enable one-click exports that feed the data into Excel, produce mail-merge ready form letters, or create custom on-screen/printable reports Technical notes • Source files are standard comma-delimited and tab-delimited text or other • Front-end can be Access or an Excel interface, as long as it...

I have several production PL SQL scripts that are starting to show their age: execution times have crept up and they are consuming more CPU and memory than I am comfortable with. The primary focus of this project is therefore PLSQL itself, not application-level logic or UI work. What I need from you is a careful optimisation of the existing codebase. The goal is two-fold—raise overall performance and cut back on resource usage—without changing the functional output in any way. You will be working with code that is already in use, so a light-touch, incremental approach that can be verified against current results is essential. Deliverables I expect • Revised PL SQL scripts ready for drop-in replacement • A short before/after performance summary (timings and resourc...

I am looking to have a self-contained desktop application built that lets us record and track three key data sets in one place: staff information, individual training records, and detailed instrument-calibration histories. The program will be used on a small internal network, so a local database engine such as SQLite, MS Access, or an embedded PostgreSQL instance is perfectly acceptable as long as installation remains straightforward for non-technical users. Two role levels must be enforced: Admins need full create / update / delete privileges plus the ability to add new users, import legacy spreadsheets, and run global reports, while Managers only require read-only dashboards and the ability to print or export filtered reports for their teams. Typical daily tasks should feel intuitive: ...

I already have the full site code zipped and waiting in my account; what I need now is a reliable pro who can drop it onto my hosting, get the domain resolving cleanly, and make sure every internal link and asset loads as intended. First you’ll spin the files up on my server (cPanel access provided), create the database if the site needs one, and confirm SSL is active. Once it’s live, set up the core pages—Home, About Us, and Contact Us—so the menus, breadcrumbs, and footer navigation all point correctly. Next comes the outbound linking work. I want visible, working icons for Facebook, Twitter, and Instagram, plus clear buttons for my Go Fund Me campaign and my crypto wallet address. If you can place the wallet address behind a copy-to-clipboard button, even bet...

Project Overview We are building a proprietary algorithmic trading system hosted on Google Cloud Platform (GCP), using Interactive Brokers (IB) as the brokerage for live market data and order execution. This is a serious, long-term project — Phase 1 is the foundation that all future phases will be built on. We need a skilled developer who has hands-on experience with the Interactive Brokers API (TWS API / IB Gateway), GCP infrastructure, and Python-based financial data systems. You will set up the cloud environment from scratch, build the IB connectivity layer, create the Python database, and deliver clean, documented, production-quality code. This is not a one-off script job. You are building infrastructure that will run live capital. Reliability, security, and documentation are n...

I need my NZPack-powered NinjaTrader environment configured from scratch so I can reliably backtest and refine a metals strategy (gold and silver). Your task begins with a clean install: connect to my machine through the temporary remote credentials I will supply, load NZPack, adjust any dependencies, and verify that every component compiles without errors. Because I don’t yet have the historical data, please locate a high-quality tick or one-minute feed that covers at least the past five years of COMEX gold and silver futures, import it, and build the necessary databases so the platform can run fast, repeated simulations. Once the data is in place, run representative backtests that highlight the performance of my current template. I am interested in performance optimisation rather...

I need a Mac-native desktop (potentially working on cloud or backing up to cloud and can input data to from mobile or windows) application that will house a clinical database for a defined cohort of patients and their related diseases. The data model itself is straightforward—basic demographics, diagnosis codes, treatment timelines, and outcome notes—but a few smart features are critical to daily use: • Multiple input channels. Clinicians must be able to type directly into clean, well-labelled forms, import legacy records from CSV or Excel, and drop scanned documents that the system will pass through OCR, automatically mapping recognised values to the correct fields. • On-the-fly calculations. Once records are saved, the app should detect recurring patterns, run p...

I need a comprehensive dataset of FMCG items that already includes each product’s bar code. You do not need to limit yourself to one category; feel free to pull records from food and beverages, personal care, household items, or any other fast-moving line you have reliable data for—the broader the coverage, the better. Please structure the final file so it can be imported directly into a database. I will adapt it to my own environment, so a clean, well-documented import format is essential (CSV wrapped in a SQL-ready script, JSON dump, or any other approach that drops smoothly into a relational or NoSQL store is fine as long as the mapping is clear). Key fields I must see per record: product name, brand, bar code (EAN/UPC), pack size or net weight, category, and MRP. Extra at...

I have a collection of digital Excel workbooks that must be imported into a live database. Each workbook contains structured records; your task is to move every field into the corresponding table and verify the integrity of the import so the data is immediately usable. The work is purely database entry—no text transcription and no spreadsheet cleanup. You will receive the Excel files exactly as they sit on my drive, and I will provide the database schema along with any lookup tables you might need. Please keep existing column names intact unless we agree on a mapping change in advance. Key deliverables • Populated database with all records from the supplied Excel files • A brief validation log noting any skipped, merged, or corrected rows • Confirmation that pr...

I need a full-stack web application built from concept to live deployment. This includes planning the architecture, designing an intuitive responsive interface, implementing secure back-end logic, integrating a database, writing clean APIs, and setting up automated tests as well as CI/CD pipelines. The finished app must run smoothly on modern browsers, scale easily in a cloud environment, and come with clear documentation so I can maintain or extend it later.

I need a new Cognos dashboard focused purely on data visualization. The dashboard will pull its figures from our existing SQL databases, so you’ll be working with relational data structures, writing efficient queries, and making sure refreshes stay fast even as record counts grow. The look and feel matter to me: clear charts, intuitive drill-downs, and a layout that lets managers grasp trends at a glance. If you have experience shaping Cognos visualizations with custom prompts, calculated fields, and conditional formatting, that’s exactly the skill set I’m after. Deliverables • A fully functional Cognos dashboard connected to the specified SQL sources • Reusable data modules and any query subjects you create • Brief setup notes so my internal admin ca...

I have an in-house VB.NET application backed by SQL Server 2008 R2 that currently schedules four 6-hour shifts per day. Operational changes now require three 8-hour shifts instead. The change touches two main areas: • Business logic – all routines that build the daily roster, assign staff and calculate shift boundaries work off the 4 × 6 model. • Database structure – several tables store fixed shift identifiers, start / end times, and downstream references that assume four records per day. Because the scheduling and allocation algorithms drive time-sensitive workflows, any adjustment must keep existing calculation accuracy intact. The user interface itself can stay as is; only back-end logic and schema need attention. What I need delivered 1. Updated ...

I look after supply management for a medical provider that serves the LGBTQ+ community. We have just consolidated everything into a single distribution hub, and from this point forward that hub will handle every inventory-related task for all of our clinic locations. To keep pace, I need our inventory tracking to move from manual spreadsheets to a fully automated, scalable workflow that plugs straight into the software stack we already use. First priority is real-time stock visibility. As soon as an item is received, dispensed, or transferred between sites I want its quantity to update instantly across the system. Barcode scanning at each touchpoint is essential so staff can work quickly without typing errors. Low-stock alerts will come later, but the foundation has to be bullet-proof tra...
