Tiwari

Hi, I’m Sachin - 3+ years shipping product. I graduated from IIT (BHU), Varanasi in 2023 with a B.Tech in C.E (CPI 8.72). Software Engineer 3 at Cohesity (Go, Kubernetes, EKS). Before that, backend at JAR: three microservices from scratch, ₹18M payout save, hybrid-encrypted KYC for 30M users, Redis leaderboards that moved GMV.
