Key Strengths
- Designed and evolved a real-time messaging/networking backend with low latency and high reliability
- Pragmatic architecture tradeoffs for MVPs (Socket.IO vs raw WebSockets; monolith vs microservices)
- Strong focus on data integrity and privacy (strong consistency for user-facing actions)
- Scales Python/FastAPI APIs using async patterns, Redis caching, and idempotent endpoints
- Contract-driven, versioned APIs with OpenAPI documentation to enable frontend integration
- Led incremental backend refactors with stable external APIs, feature flags, backward-compatible migrations, and staged rollouts
- Deep auth/security implementation: JWT best practices, short-lived tokens, refresh rotation, revocation strategies
- Proactively identified and mitigated edge cases (concurrent refresh causing stale/duplicated JWTs)
