// ABOUT & PHILOSOPHY

README.md

SOFTWARE ENGINEER & AI RESEARCHER High Impact

Hi, I'm Subhadeep Chell.

Currently an upcoming SDE at TCS, after driving full stack enterprise microservices and cloud engineering at Cognizant. I specialize in building end-to-end full stack web platforms, distributed backend microservices, and applied AI systems.

My approach combines Apple's design philosophy—where every layout breathes with intentional whitespace—with the raw performance and developer ergonomics of Linear and Vercel.
