I’m Himanshu, an Engineering Manager and backend specialist with 8+ years of experience building and scaling products used by 200M+ users across gaming, fintech, and SaaS. I currently lead the Marketing Suite product at Playlist, and previously led the User Services pod at Winzo, owning systems running at 1M+ RPM and driving org-wide engineering processes like on-call, monitoring, and delivery excellence.

Team building, hiring, and engineering org design 4. System rewrites, microservice migrations & performance tuning 5.
