/aboutMe
A glimpse into who I am, what I've built, and the journey so far.
I'm a 29-year-old Senior Software Engineer based in Bengaluru, India, originally from West Bengal.
With NaN+ years of end-to-end ownership across high-traffic, scalable web and mobile products serving millions of users, I specialize in React.js, Next.js, and TypeScript. I have production experience integrating LLMs (GPT-4o, Claude) and agentic AI pipelines into customer-facing systems at scale. I thrive on leading 0-to-1 product initiatives, defining frontend architecture standards, and driving measurable business outcomes through technical leadership and cross-functional collaboration.
