I'm Param Raj, a full-stack engineer with 4.5+ years of experience in React/Next.js, Node.js/NestJS and AI integrations. I work part-time on contract (about 15–20 hours a week), overlapping with US mornings.
AI chat, RAG search, agents and workflow automation added to the product you already have.
I take part of your backlog part-time while you search for a full-time engineer.
Slow, broken or outdated React and Node apps and dashboards: I find what's wrong and fix it, or rebuild the parts that need it.
A working v1 of your product in 4–8 weeks, in your repo.
Paid video courses streamed from Amazon S3, Razorpay checkout with server-side payment verification, OTP sign-up, JWT auth with a mutex-guarded token refresh, device-limited logins (FingerprintJS) and a referral program with an affiliate dashboard.
AI workplace platform (confidential)
Integrates GitHub, Gmail, Outlook, Teams and HubSpot. I built the action engine that lets the AI take real actions through OAuth-scoped APIs, with human-approval steps, async Celery task queues, idempotency and audit logging.
Action engine
About 9:30 AM–1:30 PM ET (7:00–11:00 PM IST) on weekdays.
Written updates, a short demo of working software every week, and a shared board.
The code goes into your repo from the first commit.
A part-time monthly contract, a fixed-scope MVP, or a fixed-price fix.
Pricing depends on scope. I'll give you a clear quote after a 15-min call.
Tell me what you're building and where you need help. I'll reply by email to set up a call.
