Lead three verticals - Identity, Web & Dazzle(Engagement) charters for the JioCinema App.

Oversaw multiple migrations at scale:

• Migration from Voot to JioCinema, 2023.
• Migration of JioCinema to JioHotstar, 2025.

Launched multiple features to bring parity with other OTTs, and crafted some which were industry first.

• Managed hundreds of millions of user records alongside working knowledge of scaling up for 50 million concurrent users for live events.
• Engagement features involved designing systems that could handle upto 150 million visitors every day and continue to work during backend downtimes gracefully. (exponential backoffs, thundering herd handling, client side caching, CDN offloads)
• Worked closely with business and product stakeholders to deliver incremental value while ensuring engineering excellence was maintained with quality, observability and reliability.
• Implemented a strong operational process in the team to reduce untoward incidents. Yet, run a rigorous (blameless) Incident Review process to avoid future ones.
