Migrated the app’s state layer from setState to a Riverpod-based no-setState architecture, cutting unnecessary widget rebuilds and improving UI Read more performance across the Stocks, Mutual Funds, and Bonds modules. Built a Server-Sent Events (SSE) streaming layer powering a real-time, token-by-token AI chat assistant within the app, eliminating polling overhead. Designed a hybrid caching layer for the chat – an in-memory LRU cache (cache-aside + write-through, 8 sessions ×60 messages) fronting durable SQLite (Drift) storage, plus a debounced streaming flush buffer – making recent-conversation reopen instant and cutting redundant writes during streaming. Integrated Account Aggregator (AA) for consent-based financial data access and shipped rich push notifications (im- ages/actions) on Android and iOS to boost engagement. Engineered a unified GitHub Actions CI/CD pipeline (build, code-signing, unit/widget tests, artifact distribution) with single- command build automation for Android/iOS, and owned release governance across Google Play (Closed/Open/Production) and first-time App Store Connect/TestFlight rollout; resolved an App Store rejection via compliant In-App Purchases. Authored unit and widget tests for critical modules and instrumented the app with Firebase Crashlytics, PostHog, Mix- panel, and MoEngage, improving crash visibility and release confidence.

Built and scaled Bharat Khata, Retailer App, and Farmer App (Flutter) to 1.5L+ downloads, driving Rs. 150+ Cr in BNPL loan disbursement and Read more onboarding 90,000+ farmers. Built a reusable in-house UI component library that cut feature development time by 40%, and localized the app into 7 languages, lifting rural adoption by 20%. Architected the app using MVC/MVVM with Riverpod/Provider state management and GoRouter (deep links), and adopted ISAR for efficient on-device storage of large datasets. Integrated Firebase Auth/Firestore, REST APIs, and KYC SDKs (Hyperverge, Digio, Digitab); built supporting backend REST APIs in Node.js/Express and Strapi CMS. Deployed MoEngage, AppsFlyer, and Google Analytics with push notifications/deep linking, and executed zero-downtime data migrations during system upgrades.

Built multi-container Docker/Docker Swarm environments (Prometheus, cAdvisor, Redis) and Grafana/Prometheus monitoring for a real-time hospital Read more asset management system.

Owned end-to-end REST API development and manual testing (Node.js) for the Hero Corp insurance broking portal within an Agile team.
