About this gig
Need a Full-Stack Developer Who Can Handle Everything From Backend to UI?
Hi, I'm Ajay a Full-Stack Developer with ~10 years of experience building scalable web applications, APIs, admin panels, and custom platforms for startups and businesses.
Most web apps look fine on day one and struggle when real users arrive. I build full stack apps with a React frontend and a Node.js/NestJS backend designed to hold up: clean architecture, a solid database and code your next developer can work with.
WHAT I BUILD
- Web platforms, dashboards, marketplaces and member portals
- React frontend connected to REST or GraphQL APIs
- Login with JWT or OAuth2 and role-based access
- Real-time chat and notifications with WebSockets
- Payments, emails and background jobs with Redis queues
- Deployment on AWS, Docker or Railway
THE BACKEND DIFFERENCE
I lead a backend team and set the architecture, database design and code standards others follow. You get that lead-level planning, and I write the code myself. For a repeat US client on Fiverr, I built a platform with live direct messaging and user profiles.
HOW I WORK
- Fixed-price plan with milestones before you order
- Regular progress updates and demos
- Clean hando

I'm Ajay, a full stack developer with ~10 years of experience and a team lead who still writes the code. I build React and Node.js/NestJS web apps with real backend depth: clean APIs, solid PostgreSQL/MongoDB design, Redis queues, real-time chat and AWS deployment. I've run Stripe, Razorpay, PayPal, Xendit and more in production, and shipped LLM features that process real documents. Before you order, you get a fixed-price plan with milestones. I've built products for clients in the US and Malaysia, including a repeat Fiverr buyer.

FAQ
Can you work on my existing codebase?
Yes. I review the code first, then add features or refactor in small, safe steps without breaking what already works.
Which database will you use?
Usually PostgreSQL for relational products, MongoDB where a flexible schema fits better, and Redis for caching and queues. I explain the choice in your plan.
Do you design the UI too?
I build clean, responsive React screens from your design or a simple layout we agree on. For a fully custom look, share Figma files or a reference site.

Ajay did a great job, I would definitely recommend. We just finished phase 1 of our website with live Direct Message and Profiles for our clients. Ajay Nailed it. the only reason we need a phase 2 is because I was not clear in the beginning of what I needed, and because I didnt know how skilled Ajay...
