...Full-Stack Developer Needed – NestJS + React/TypeScript Fuel Levy Pricing Engine for Rideshare Platform Job Description: I am looking for a highly skilled full-stack developer to build the first production-ready version of a vehicle-specific fuel levy / energy levy pricing engine for my rideshare platform based in Queensland, Australia. This system must be designed as a secure backend-driven pricing engine, where the commercial logic remains private on the server and is not exposed to the browser. The purpose of the system is to calculate a fair trip-based fuel or energy levy using approved vehicle data and live/local fuel pricing inputs, with support for petrol, diesel, hybrid, and EV vehicles. The backend must be built using Node.js, NestJS, TypeScript, Prisma, an...

I have a steady flow of bite-sized projects that blend React, TypeScript, JavaScript and Tailwind CSS on the frontend with Node.js, Supabase, PostgreSQL and NeonDB on the backend. Each task is already broken down, fully documented and accompanied by the access keys you’ll need, so you can concentrate on building rather than guessing. Because the assignments are short and the deadlines are tight, the only things that matter are clear communication, clean code and the ability to push working features fast. Whether you feel strongest on the UI side, the server side or somewhere in between, as long as you can demonstrate working knowledge of the stack and deliver to spec, we’re good. Expectations are simple: pick up a ticket from the documentation portal, follow the instru...

...authentication layer. The stack is TypeScript end-to-end, PostgreSQL for storage, and a React front-end that will consume your work through a clean RESTful API. Everything lives on a Linux server, so familiarity with its ecosystem is essential. Your main mission is to design and implement a rock-solid user authentication system—think sign-up, login, refresh tokens, password resets—while keeping performance tight and code readable. Alongside the coding, I need you to lock the server down: enforce SSL, fine-tune PostgreSQL roles, manage environment secrets, set up firewalls, and apply best-practice hardening so that security audits pass without a hitch. Deliverables: • Fully documented REST endpoints for all auth flows • PostgreSQL schema/migrations writte...

I’m upgrading our learning platform with a lightning-fast student dashboard and an in-browser code editor that feels indistinguishable from VS Code. The stack is already fixed— with TypeScript, Tailwind CSS for styling, Supabase for auth and data, Monaco for the editor, and Judge0 as the execution engine—so you can dive straight into building rather than selecting tools. What I need built first is the student-facing dashboard, and within that the priority feature is real-time performance metrics that update without a perceptible lag. From there, you’ll wire in Monaco (with C++ and Java language services) and stream submissions to Judge0 so students see compile-and-run results instantly. Once the learner experience is rock-solid, we’ll extend the same d...
