PostgreSQL Jobs

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. You will own end-to-end development: refining tickets in our Monday morning grooming call, writing clean, well-tested Node services, and pushing pixel-perfect React components that match Figma specs. I deploy through a GitHub-driven CI/CD pipeline to AWS (ECS + RDS). Familiarity with GraphQL, PostgreSQL, Docker, and Jest is helpful, but solid Node.js fundamentals and modern React experience are the non-negotiables. Success is straightforward. By the end of each two-week spr...

I am building a web application and want one proven engineer to take full ownership of the tech. The current plan is React on the front end and Python on the back end; if you favour Django, FastAPI, or another modern framework that fits, make the case and run with it. You will design the database, craft the APIs, set up the cloud infrastructure, and push clean, tested code to production without constant check-ins. You should have around eight years of hands-on experience shipping real products, be equally strong in frontend and backend work, and communicate clearly in brief updates. Compensation starts hourly while we shape the MVP. When revenue starts flowing you convert to a 40 percent share, giving you genuine skin in the game. To move forward, show me something real you have built&m...

I’m building a Python-based web application whose core job is to streamline order management while exposing clean, well-documented APIs. The main stack is Django for the web layer, but I also want to leverage both Django Rest Framework (for the bulk of the REST endpoints) and a lightweight FastAPI micro-service where low-latency calls are critical. Here’s what I need from you: • Set up a fresh Django project (latest LTS) with models that cover orders, items, customers, and basic inventory counts. • Expose CRUD and filtered list endpoints through Django Rest Framework, secured with token or session auth. • Spin up a separate FastAPI service—running side-by-side or in a Docker container—that handles a performance-sensitive subset of endpoints ...

I need a streamlined tracking and archiving system that lets my construction team capture three critical data streams—employee activity, project status, and equipment usage—and roll them into a single, at-a-glance dashboard. Think of it as our daily command center: supervisors should be able to log in, see real-time updates, and drill down to historical records without shuffling through spreadsheets or paper logs. Core expectations • A structured back-end (SQL, PostgreSQL, or another reliable database you recommend) where those three data categories live in clearly separated tables but can be cross-referenced quickly. • A web-based dashboard—desktop first, mobile responsive—showing live summaries, colour-coded alerts, and simple filters for date range...

I’m building a mobile platform that lets our NBFC’s direct selling agents create loan applications on the go while giving loan officers a pocket-sized console to review and approve them. The tech stack is fixed: React Native on the front end, Spring Boot micro-services with PostgreSQL 13 on the back end, all traffic funneled through Kong as the API gateway. Here’s the flow I need: an agent signs in, opens a guided form, attaches documents, and submits. The request lands in a Spring Boot service, is stored in Postgres, and appears instantly in the loan-officer view for approval or rejection. Push or in-app notifications should alert both parties at every status change, and every action must be logged for audit. I will supply wireframes, the provisional DB schema, and acc...

The system must handle ERC20 token deposits for USDT and USDC on Ethereum addresses, detect blockchain reorgs, handle Bitcoin RBF transactions, and include a gas top up bot for Ethereum sweeps.

My app already handles sign-in with username and password and stores everything in a relational database (MySQL/PostgreSQL). I have three tables: • users • doctors What I need now is the logic that, immediately after a successful login, returns only the doctors connected to that specific user.

Provide clear comments or brief documentation so I can extend the filter when I add new roles. 3. Deliver tested code (SQL statements, ORM scope, or framework middleware—whichever fits) that plugs straight in...
