Hey, I'm Arnab.
Backend & AI engineer.
Upcoming cohorts:Production Django + GenAI→Currently at Inferstrat — GenAI, marketing analytics, and ads infrastructure. Before that, 4 years at Pixis (Series C, AI ad platform, 2019–2023) and a short stint at EvenRank Data Science (distributed web crawlers, 2019).
On the side I run Stackedtensor, my personal lab where I ship a handful of products under one roof. I'm also preparing my first two live cohorts — production Django and GenAI engineering — opening for enrolment soon.
