Project details

You will get a clean, documented REST API built in Node.js and TypeScript, backed by a properly designed PostgreSQL or MongoDB schema and handed over with source code you fully own.

I have spent close to a decade building and fixing backend systems for startups and product teams, so the work goes beyond "it returns 200". You get input validation, authentication and role handling, sensible error responses, indexes and queries that hold up as data grows, and a README that lets your next developer pick it up without a handover call.

Choose the Advanced tier and I also containerise the service with Docker, wire up CI/CD, deploy to AWS, and set up logging and monitoring so you can see what is happening in production.

Not sure which tier fits? Message me with what you are building and I will tell you honestly, including if the smaller package is enough.

I build and fix the backend systems that businesses run on — APIs, databases, and cloud infrastructure that stay fast and predictable as traffic grows.

What I do:
• Backend APIs in Node.js, TypeScript, NestJS and Express — designed, documented (OpenAPI), and tested
• Database engineering — PostgreSQL and MongoDB schema design, migrations, indexing, and query tuning
• AWS architecture and cost reduction — ECS, Lambda, RDS, S3, CloudFront, Docker
• Integrations — Stripe and payment gateways, OpenAI, POS and third-party APIs, webhooks with idempotency and retries
• Inherited codebases — I read existing code and work inside its conventions instead of proposing a rewrite

Recent work:
• Backend for an EV charging platform monitoring 1,000+ chargers in real time
• AI-driven lead generation SaaS (Node.js, MongoDB, Next.js, Playwright)
• AWS infrastructure rework that cut a client's monthly cloud spend by over 30%

How I work: I scope before I code, send a written plan you can correct, flag assumptions instead of guessing silently, and give you daily written updates. You get production-ready code, migrations that are safe to run, and documentation your team can actually use.

Available 30+ hrs/week with EST/CET overlap. Tell me what's breaking or what you need built, and I'll tell you honestly whether I'm the right person for it.

Steps for completing your project

After purchasing the project, send requirements so Harvinder can start the project.

Delivery time starts when Harvinder receives requirements from you.

Harvinder works on your project following the steps below.

Revisions may occur after the delivery date.

Kickoff and API design

I review your requirements, confirm the endpoint list and data model, and send you a short plan before writing any code.

Build and test

I build the endpoints, database schema, auth and validation, with tests and daily progress updates so you always know where things stand.

Review the work, release payment, and leave feedback to Harvinder.
