What I'm looking for

I’m looking to build user-focused full-stack products—especially performance-critical React experiences and secure systems—while collaborating cross-functionally in an Agile team and mentoring others to deliver measurable impact.

I’m a Full Stack Developer currently working at Toddle in Bangalore as an SDE II, where I lead engineering delivery by spearheading a 7-person team and guiding Scrum/Agile workflows to hit aggressive timelines without compromising quality.

I thrive on performance and product impact: I diagnosed and fixed critical frontend bottlenecks with browser profiling, cutting homepage load time from 30 seconds to 4 seconds and achieving a 90%+ reduction in Time-to-Interactive (TTI) through query batching, lazy loading, caching, and virtualization.

I also build the systems that make products trustworthy and scalable—like engineering a self-serve Audit Log dashboard for real-time activity data and redesigning authorization by architecting a Role-Based Access Control (RBAC) system for fine-grained, secure access management.

Earlier, I delivered automation for academic year transitions, reducing school effort by 90% (from 2 months to under 4 hours), and as an intern I improved perceived latency with skeleton loaders and integrated OneSignal using the OneSignal SDK in the mobile app.
