About this gig

Your idea deserves more than code that works it deserves a product built to last.

I'm Pintu Kumar, a Full Stack Developer with 3.5 years of experience. I've shipped enterprise software serving 10,000+ daily users and APIs handling 50,000+ requests a day. My GitHub has 174 public repos, and I contribute to open-source projects like MUI, ESLint, Drizzle ORM, and Express.

What you get:

Pixel-clean React / Next.js frontend with Tailwind CSS

Node.js + Express backend with REST APIs

PostgreSQL or MongoDB database, designed properly

Authentication (JWT/OAuth), forms, dashboards whatever your app needs

Deployed live, with clean documented code you own fully

What I need from you: a short description of your idea, any designs or references you have, and your must-have features. I'll ask smart questions before I start so there are no surprises.

Clear daily communication, honest timelines, unlimited reasonable support during delivery. Let's build it.

  • BASIC $5 "Landing page / single page app" 1 page, responsive design, contact form, deployed live 3 days delivery 2 revisions
