About this gig

Need a reliable backend that just works? I build fast, scalable Node.js APIs and handle backend integrations end-to-end REST, third-party APIs, databases, auth, and deployment.


What I deliver:

RESTful API development (Node.js/Express)

Third-party API integrations (Stripe, payment gateways, CRMs, etc.)

Database design & integration (MongoDB, PostgreSQL, MySQL)

Authentication & authorization (JWT, OAuth)

Clean, documented, production-ready code


Why clients choose me: I write code that's easy to hand off clear structure, comments, and documentation so your team isn't stuck maintaining a black box.


Tell me about your project scope and I'll get back to you with a clear plan and timeline.

If you're building in healthcare, you already know most developers don't understand HIPAA, access controls, or audit logging until it's too late. That's where I come in. I build scalable web platforms with clean backend architecture (Django, FastAPI) and modern frontends (React, Next.js, Vue), with special focus on HIPAA-compliant EMR/EHR systems, proper access controls, audit trails, and data security done right from day one. Beyond healthcare, I work on AI-powered SaaS platforms, LLM integrations, workflow automation, and data pipelines across FinTech, EdTech, and PropTech.

    The worst developer I have worked with in my life. I have been with Fiverr since 2011, and I have never had such an experience this bad. I wish I can list the number of bugs, problems and incomplete work this seller has left me. I had to pay multiple people to fix and complete his work. Seller has delayed...
