NoSQL Couch & Mongo Jobs

I want to stand up a full-stack IIoT environment on AWS tailored for a manufacturing plant. The platform must ingest machine performance data from shop-floor sensors, stream it securely into AWS, and expose three core capabilities: real-time monitoring, predictive maintenance, and rich analytics with clear reporting dashboards. The flow I have in mind uses AWS IoT Core or Greengrass at the edge to collect OPC-UA/MQTT payloads, routes them through Kinesis or Kafka (open to your suggestion), lands the raw data in S3, and writes curated time-series to DynamoDB or Timestream for fast queries. From there I need: • Live dashboards (Grafana, QuickSight, or a similar tool) that show cycle times, throughput, and alert me the moment a metric drifts outside tolerance. • A predictive mai...

I need to retire my old Microsoft Access commission-tracking database and move everything to a cloud-based interface that staff can reach from any browser. You will start with the full Access file (forms, queries, VBA, and data) and rebuild the same business logic online. Two elements must make the jump intact: • Customizable commission calculations that let me change rates, tiers, and effective dates without touching code. • Built-in reporting and analytics so managers can slice results by salesperson, product line, and period, then export to Excel or PDF. Beyond those, I’m happy to discuss best practices—user authentication, audit trails, or dashboards—if they fit naturally into the new architecture. I have no fixed preference for the front-end stack; f...

Project Overview I'm building RailWise AI — a web app that helps Indian train travellers find the most reliable route to their destination, not just a ticket. The core idea: instead of just showing train options, we score every journey from 0–100 based on confirmation probability, delay risk, transfer risk, and cost. Think of it as a reliability engine on top of Indian Railways data. What needs to be built (MVP only — keep it simple) A simple web interface where user enters source station and destination station Backend fetches available train options by scraping (availability data) A scoring engine that calculates a Reliability Score (0–100) for each journey option based on logic I will provide in full detail (already documented) Results page showing top 3...

I’m replacing our summary-based workflow with a true Retrieval-Augmented Generation pipeline and need a collaborator who can own both the backend and the React front end. The core objective is accuracy: every PDF we receive from clients must be chunked, embedded, stored in Qdrant, and then retrieved at query time so the language model can cite exact passages, never a lossy summary. You’ll wire this flow together with Python services and Node/Fastify APIs, expose it to the UI in Typescript/React, and keep everything humming inside our OpenAI-powered evaluation layer. What I’ll lean on you for • Architecting and implementing the end-to-end RAG pipeline (chunking strategy, embedding jobs, vector-store schema, retrieval functions). • Building real-time docum...

I have a fully-functional codebase that combines a front-end, an Express API, and Prisma for data access. Everything runs correctly on my machine, but it still lives only in development. I now need it deployed to production using the stack I have already chosen: on Vercel, the Express server on Railway, and an existing Supabase Postgres instance. The database is set up and populated, so there is no migration work required. What I do need is the entire deployment workflow put in place, along with any environment-variable wiring I may have missed. I can provide the actual secrets; I just need clarity on what must be set where so that the front-end talks to the API and the API talks to Supabase through Prisma. Deliverables • Live, publicly accessible site on Vercel • Expres...

I have a Windows-only program that performs intensive text-based data processing. It ingests large text files, runs a series of transformations and validations, then presents the results in a simple desktop UI. I now need the same workflow available in any modern browser, built with Node.js on the back end. The existing logic is well-structured and written in C#; I can provide the full source, sample data sets, and a short functional spec that explains each processing step. Your task is to port the core algorithms, recreate the current screens as responsive web pages, and ensure the output matches the desktop version byte-for-byte. You are free to choose frameworks that fit the Node.js ecosystem—Express or Fastify for routing, a templating engine or React/Vue for the front end, and...

Project Overview: We have a live application on the App Store and we need an expert to implement a sophisticated "User Support/Donation System" using PayPal Business API. Technical Requirements: 1.

I’m launching a web-based social network and need an experienced developer to take it from concept to a live, scalable platform. The core build must include secure user registration and login, a real-time activity feed, follow/friend functionality, direct messaging, notifications, profile editing, and a simple admin dashboard. Responsive design is essential so the service feels seamless on phones, tablets, and desktops. I’m flexible on the stack, though a modern front-end framework such as React or Vue paired with a robust back end (Node.js, Django, or similar) and an SQL or NoSQL database would be ideal. Clean RESTful (or GraphQL) APIs are important because I plan to introduce a companion Windows desktop client later, so please architect with that future integration in mind. ...

I’m building a brand-new web application under a fast-moving startup and I need one dedicated engineer to own the full stack from day one. We operate on California (PST) business hours, so you’ll work those hours alongside me and the design team, collaborating live through Slack, GitHub and Zoom. The core of the product is a React-driven front end, coupled with whatever back-end stack you’re most productive in—Node/Express, Python/FastAPI, or a comparable RESTful setup. You’ll start with green-field architecture decisions, set up CI/CD, wireframes to working screens, database schema, APIs, automated tests and production deployment. This is a full-time, monthly-salary role and I’m hiring an individual developer only—no agencies or teams. Automa...

I run a product-led SaaS company and need a full-stack engineer who can work the same hours I do—9 am – 5 pm Pacific Time, Monday through Friday. Every feature we ship is built with JavaScript from back to front, so daily work revolves around a Node.js/Express API layer feeding a React web application.
