Full-Stack Developer Needed – 15, NestJS, PostgreSQL, Stripe

We need an experienced Full-Stack Developer to jump in immediately and help us complete a critical

feature sprint inside our existing SaaS platform.

This is time-sensitive. We are preparing for a client demo and need this work completed within the

next few days.

The platform is already live and built with:

Frontend:

• 15 (App Router)
• React 19
• TypeScript
• Tailwind CSS
• shadcn/ui

Backend:

• (NestJS)
• PostgreSQL
• Prisma ORM
• Stripe (subscriptions + webhooks)
• AWS deployment

Scope of Work:

• Implement a new dashboard analytics widget using existing API data
• Optimize one backend API endpoint (performance + query efficiency)
• Improve Stripe webhook error handling and idempotency logic
• Refactor one backend module for cleaner architecture
• Add structured logging to one critical flow
• Test full flow and prepare clean PR for merge

This is not exploratory work. Architecture decisions are already made. We need someone who can

execute cleanly and fast inside an existing codebase.

Requirements

• Strong hands-on experience with App Router
• Advanced TypeScript
• Comfortable with NestJS and REST APIs
• Experience optimizing PostgreSQL queries
• Stripe checkout + webhook experience
• Clean Git workflow (branch → PR → review)
• Ability to start immediately

Deliverables:

• Working feature merged
• Optimized endpoint
• Stable Stripe webhook handling
• Clean, production-ready code
• Short summary of improvements made

We are ready to start today. If the sprint goes well, this can lead to additional feature work.

Contract duration of 1 to 3 months. with 30 hours per week.
