Sayan Das
A Full-Stack Developer, Product Designer & Startup Co-founder — turning ambitious ideas into shipped software.
I'm a 3rd-year CSE student who doesn't just code — I build ecosystems. From co-founding startups to shipping production-ready AI SaaS, I bridge the gap between complex engineering and human-centric design.

I don't just write code — I build ecosystems that connect engineering with people.
Somewhere between a terminal window and a Figma file, I found the thing I actually care about: building things end-to-end. I've founded a web agency, shipped a drag-and-drop AI page builder, and I'm currently deep in production-grade AI SaaS — always chasing the point where solid engineering and thoughtful design meet.
Interfaces
React & Next.js interfaces built for speed, accessibility and pixel-precision.
Systems
APIs, databases and auth flows designed to hold up under real traffic.
Shipping
CI/CD, containers and cloud deploys that get code to production, reliably.
Judgment
Design and DSA-sharpened problem solving behind every product decision.

A few products I've architected, designed and shipped end-to-end.

Experience & milestones.
A short list, deliberately. Every entry taught me something I still use daily.
B.Tech, Computer Science & Engineering
Built a strong foundation in core computer science principles like data structures, algorithms, and systems architecture — while designing and shipping real-world digital products on the side.
Co-Founder & Full-Stack Engineer
Founded and led a web agency building full-stack SaaS applications. Built 4+ client applications and architected a custom drag-and-drop editor with AI-assisted page generation.
Frontend Engineer Intern
