Hi, I'm Harsh — a Full-Stack & Generative AI Developer who builds fast, secure, and scalable web applications.
I work daily with Next.js, React, TypeScript, Node, PostgreSQL/MySQL, Prisma, and REST APIs, with real production experience in authentication (JWT, RBAC), Docker, and clean system design. Currently a Gen AI Engineer at SevaSYNC Digital Solutions, where I ship AI-powered products end to end.
What you get: clean code, clear communication, on-time delivery, and a developer who actually cares about your results.
Let's talk about your project.
FAQ
Do I need to contact you before placing an order?
Yes, please message me first. Every project has different requirements, so a quick chat lets me confirm the exact scope, timeline and price before you order. This avoids delays and keeps your delivery date accurate.
What details do you need to get started?
A clear description of what the app should do, any design or Figma references, your preferred tech stack if you have one, and access to existing code, database or APIs. The more detail you share, the faster I can begin.
Will I receive the full source code?
Yes. You receive complete, well organised source code with full ownership rights on every package, including Basic. There are no hidden files and no license restrictions.
Which technologies do you work with?
Next js, React, TypeScript, JavaScript, Node, REST APIs, PostgreSQL, MySQL, Prisma ORM, Redux Toolkit, JWT and RBAC authentication, Docker and Tailwind CSS. I also build AI powered features and integrations.
Can you work on my existing project instead of building from scratch?
Yes. I can fix bugs, add features, improve performance or refactor an existing Next js, React or Node codebase. Please share the repository so I can review it and confirm the effort before you order.
Do you provide support after delivery?
Yes. Every order includes free bug fixes for the delivered scope. If you need longer cover, you can add the bug support extra for ongoing maintenance and small updates.
Will my website work properly on mobile?
Yes. Responsive design is included in every package, so your app will look and work correctly on mobile, tablet and desktop. I test across all major screen sizes before delivery.
Can you deploy the app and connect my domain?
Yes. I can deploy to Vercel, Netlify, Render or your own server, configure the database and environment variables, and connect your custom domain. Included in Premium, available as an extra otherwise.
