Who I
Am?
I'm Supratik, a Software Analyst with 7+ years designing and delivering scalable web applications. My journey spans the full product lifecycle — architecting frontend systems to integrating complex backend APIs.
Currently at Valuelabs (Client: Shutterfly Inc.), I lead development of high-traffic product customisation features used by millions. I believe great software lives at the intersection of engineering precision and deep user empathy.
I thrive in large codebases, love mentoring junior developers, and actively leverage AI-assisted engineering workflows to ship high-quality software faster.
