Platform and backend work: async job workers, subscription billing, real-time integrations, secure webhooks, and AWS/Turborepo/Bun tooling.

  • Wrote async job workers with BullMQ + Redis using lease-lock heartbeat coordination and exponential backoff, bringing duplicate job executions to zero across restarts.
  • Shipped a subscription state machine covering coupon-reserved renewals, scheduled plan changes, and cancellation-at-period-end, cutting billing escalations by ~40%.
  • Wired up real-time market data via Fyers WebSocket with protobuf decoding and auto-reconnect, tracking 200+ symbols live and closing trade calls within <100ms of a target/stop-loss hit.
  • Added timing-safe HMAC verification and a DB-backed replay guard to webhook ingestion, eliminating replay-based double-charges from Digio and KRA in production.
  • Built coupon dispatch over AWS SES and WhatsApp (WATI) with row-level locking and DB check constraints, hitting 97%+ delivery success and ruling out duplicate sends.
  • Set up a Bun + Turborepo monorepo with branch-based CI/CD and blue/green container switching, cutting deployment time by ~50% over the old shell-script workflow.
