Led end-to-end development of UPI, IMPS/RTGS/NEFT Bank Transfers, Rewards & Cashback systems for Kotak 811 serving 10M+ MAU. Reduced fraudulent transaction exposure by integrating BioCatch behavioral biometrics and AppsFlyer attribution SDK, enabling real-time anomaly detection and improving marketing attribution accuracy across 10M+ user sessions monthly. Reduced app cold-start time by 30% for a 10M+ MAU banking app by leading a React Native version upgrade paired with Hermes engine enablement, lazy module loading, and startup trace profiling — directly improving Day-1 retention metrics. Elevated crash-free session rate from 98% to 99.7% across 10M+ active users by instrumenting Firebase Performance Monitoring with custom traces, triaging top-crash ANR patterns, and enforcing a pre-release crash gate in the CI pipeline. Designed frontend-driven BFF (Backend-for-Frontend) integration layer reducing API latency and improving transaction responsiveness. Owned release lifecycle including deployments, staged rollouts, monitoring, and rollback strategies via App Store Connect and Google Play Console. Engineered a Fastlane-based release automation pipeline on Bitrise, scripting automated code signing, semantic versioning, environment-specific IPA/APK generation, and phased rollout triggers — eliminating manual build steps and enabling one-click production deployments for a 10M+ MAU banking app. Mentored 4 engineers and led Agile sprint planning, cross-functional collaboration across backend, QA, and product teams.

Architected and delivered scalable React Native features across Android and iOS, enforcing component-level performance budgets and code-splitting patterns that reduced JS bundle parse time measurably. Built BFF integrations to streamline REST API orchestration and reduce frontend complexity. Implemented Firebase Performance Monitoring to identify bottlenecks and improve rendering performance. Streamlined mobile release velocity by 30% by building end-to-end CI/CD pipelines on Bitrise with Fastlane lanes for automated signing, versioning, and staged rollouts to App Store Connect and Google Play Console — cutting manual release effort from 2 days to under 4 hours. Integrated monitoring tools including Instabug, NewRelic, Firebase, and Amplitude improving observability.
