VP Engineering @ Zostel

Building platforms that scale, and teams that ship.

I'm Tarun Mittal — 14+ years across backend systems, cloud infrastructure and engineering leadership, from Zomato's early days to running engineering at India's largest hostel chain.

VP Engineering
  • Cut monthly AWS spend in half — from ~$9,000 to ~$4,500 — through media, transcoding and infrastructure work.
  • Built an in-house image proxy & media server, PoC to scale-out: pages from ~70 MB to under 10 MB, CloudFront egress from 14 TB to a few hundred GB.
  • Rebuilt CI/CD on AWS with per-PR demo environments; carried the team unaffected through the npm supply-chain compromise.
  • Consolidated multi-account AWS data via DMS into one analytics DB — self-serve reporting for every team.
  • Own hiring, on-call, incident workflow, and 1:1s with every engineer.
