  • First engineering hire owning end-to-end frontend development; partnered with ex-Amazon SDM to build a SEBI-regulated investment platform used by 1,400 users, architected a React SPA with content-hash-aware service worker caching and TTL-tiered in-memory API cache, cutting 460+ redundant asset re-validation requests per page load.
  • Owned the React 18 single-page frontend across 100+ public and auth-protected routes with dedicated layout wrappers spanning investor and analyst surfaces.
  • Designed a centralized Axios-based API layer integrating ∼16 environment-scoped backend services via hostname-driven configuration, letting a single build run across production, beta, and development without code changes.
  • Architected token-based session management with a singleton TokenManager (auto-refresh, deduped concurrent refreshes, retry with backoff, deterministic logout), keeping AWS Cognito sessions stable at 99.9% session stability.
  • Implemented an OTP-based login flow (email/mobile) with session-id exchange, wrong-OTP recovery, full user-attribute hydration, and action-level auth gating that replays the user's intended action after login.
  • Built multi-step KYC and analyst onboarding journeys (SEBI verification, manual fallback, short-URL deep links, direct-to-S3 uploads), cutting form-fill time by 40% (5→3 mins) and onboarding 49 analysts in 5 months.
  • Integrated Razorpay (GST-aware paise amounts, signature-verified callbacks) and the Digio eSignature SDK with dynamic script loading and resilient callback parsing, achieving a 0% frontend failure rate on transactions.
  • Authored a service worker with request-type-aware caching (cache-first for hashed assets, network-first with SPA fallbacks), reducing redundant asset re-validation by over 50% while preserving deep links and reloads.
  • Hardened reliability and security through a single Sentry capture point with recursive PII/token scrubbing and cache invalidation on logout/expiry, resolving 191 security and accessibility audit findings.
  • Led a migration from legacy Redux thunks to Redux Toolkit slices with progressive skeleton loaders, improving maintainability and perceived rendering performance by ∼30% without risky rewrites.
