About
I'm Amit. I started as a PHP developer in 2017 and have spent the last eight years going deep on one thing: making marketplace platforms work at scale. Today I lead a six-engineer pod at Techjockey, India's largest B2B SaaS marketplace, where I've shipped products for the US and UAE markets, migrated us off on-prem to AWS, and rebuilt search and checkout from the ground up.
I care about latency budgets, P95s, and the boring infrastructure decisions that pay off for years.
