• (Jockey Wallet Platform) Designed and built a multi-vendor wallet redemption engine (POS/web/app) chose idempotency keys, Redis distributed locking, and MongoDB unique constraints over a simpler single-vendor lock after concurrent retries exposed double-spend risk across 3 payment providers; built the rollback and reconciliation path once partial vendor failures surfaced in production.
• (Jockey Wallet Platform) Designed a redemption state machine from scratch, adding TTL-based auto-cancel and compensating rollbacks after early testing showed transactions could get stuck indefinitely on slow vendor responses.
• (Picklebay Venue Booking) Designed real-time slot-inventory logic merging schedules, bookings, and manual blocks into one conflict-checked layer, after discovering double-bookings could occur when validated separately.
• (AppsCraft) Led a live production migration of theme storage from MongoDB to AWS S3 (dual-write cutover, automated parity verification) after payload growth degraded query performance avoided downtime or data loss on a multi-tenant platform.
• (AppsCraft) Designed and owned CI/CD pipeline architecture (GitHub Actions -> Expo EAS async builds; Dockerized deployments) for mobile release workflows.
• (EMPOWER) Designed shop-scoped multi-tenant REST APIs and data models with OAuth-authenticated sessions and role-based access, supporting bulk operations across large employee cohorts.
• (Titan OMS) Reduced a critical order-processing API from 2 minutes to <300ms by redesigning MongoDB aggregation pipelines and indexing on a 1M+ document collection.
