I will build nestjs rest apis with nodejs and postgresql
Haris Javed
About this gig
Your API returns the wrong data, throws in production, or does not exist yet. I build and debug Node.js REST APIs with NestJS, TypeScript and PostgreSQL.
5+ years of software engineering. I built the marketplace order and shipping services behind ShipNest, and fintech services with NestJS, TypeORM, GraphQL and gRPC at DCore.
What you get: REST endpoints with real input validation. PostgreSQL schema, queries and integration. Existing endpoints debugged, with the cause explained in plain terms. Full source code and handover notes.
Start small. Send me the endpoint that is failing and order Basic for 25 dollars: I find the cause, fix it, and tell you what actually broke. Standard is one complete CRUD resource with validation and API docs. Premium is a feature across two related resources, with tests.
Hosting, paid third-party accounts and their fees are not included. Auth providers, payment flows and heavy data migrations are quoted separately, so describe what you need and I will send a custom offer.

I'm a software engineer with 5+ years of experience building web apps, SaaS platforms, APIs and mobile apps. My work includes ShipNest's marketplace and shipping workflows, VitalsVault's healthcare platform, Viaductus's M&A marketplace and AstroLink AI's mobile app. I work with React, Next.js, Node.js, NestJS, PostgreSQL, Supabase and React Native. I can build a scoped MVP, add features to an existing product, connect APIs or fix backend issues. You can expect clear communication, practical engineering and source code with a straightforward handover.

FAQ
Can you fix an existing backend?
Yes. Send the expected behavior, steps to reproduce the issue and redacted error details. Basic covers one agreed, reproducible issue in an existing NestJS endpoint. I will confirm scope after reviewing the relevant code.
Are authentication, payments and hosting included?
Standard and Premium use your existing authentication. New authentication, payment flows, complex migrations and third-party integrations need an agreed custom scope. Hosting and paid services are not included. Source code and handover notes are included.
Which package do I need?
Basic covers one agreed reproducible endpoint bug. Standard covers up to four REST endpoints for one resource; Premium covers up to six endpoints across two related resources. Both use existing auth. Unsure? Message me before ordering so I can confirm the scope.
What do you need from me to start?
Repository access or a zip of the code, the database schema or credentials for a dev environment, and the steps to reproduce the problem. If you do not have all three, send what you have and I will tell you what is missing.
What if the fix turns out to be bigger than one bug?
I tell you before doing any extra work, with a price for the rest. You are never charged beyond the package you ordered without agreeing to it first.
Will you work in a codebase you did not write?
Yes, most of it is. I follow the patterns already in your project instead of rewriting it in my own style, so your team can still read it after handover.
