Ayan Kumar Saha

Full-Stack Engineer

I build web and mobile products end to end, from the database schema to the last pixel. Six years in, I still like shipping best.

I build software for a living and I genuinely like it. I’ve worked across the stack: frontends, backends, mobile apps, wearables, DevOps and cloud infrastructure. The problems kept pulling me in different directions, and I followed.

Outside work I read about personal finance and how businesses work, and I follow cricket closely. I’m based in Chandannagar, West Bengal, India, and open to remote work and freelance projects, especially ones that involve something I haven’t done before.

How I work with clients

  1. 1. Understand and explore

    I start by listening. We talk through your idea, your goals and what success looks like, so I build the right thing, not just something.

  2. 2. A clear plan

    Before any code, we agree on what’s being built and how. No surprises, no scope creep: a roadmap we both understand.

  3. 3. Design preview

    You see how the product looks and feels before I build it, and we adjust it together until it’s right.

  4. 4. Build

    I work in focused cycles and send regular updates, so you always know where things stand.

  5. 5. Launch

    I handle the deployment. Your product goes live cleanly, tested and ready for real users.

  6. 6. Ongoing support

    After launch I stay around to fix issues, add features and help the product grow as your needs change.
