NestJS developer for Budgetting App
Zeeshan has been absoltey vital in making our project successul. He works incredibly hard, he's committed, efficient and gives everything to make a project a success. He's worked with us for 9 months to build an extremely complex app, and for a next app he's the fist person I would bring on board again.

I help founders, startups, and businesses build scalable full stack web applications using Next.js, React, Node.js, NestJS, TypeScript, PostgreSQL, MongoDB, AI and AWS.
My work usually fits when you need a reliable developer to turn an idea, product requirement, or existing system into a stable web application that can actually launch and scale.
With 8+ years of full stack development experience, 50+ delivered projects, Top Rated Plus status, and AWS Solutions Architect certification, I bring both technical execution and product understanding to the build.

𝗛𝗼𝘄 𝗜 𝗪𝗼𝗿𝗸
I start by understanding the product goal, users, core features, and technical requirements.
Then I map the architecture, database structure, API flow, frontend experience, and deployment approach before moving into development.
This keeps the project organized, reduces rebuilds, and gives you a clearer path from idea to launch.
The goal is to build a product that is clean, maintainable, and ready for real users.
If you need a senior full stack SaaS developer for your MVP, SaaS platform, dashboard, API system, or cloud based web application, send me a message and let’s discuss your project.
