- Built and launched a full-stack Leaderboard & Rewards system: scalable rankings plus a credits ledger made fault-tolerant with PostgreSQL advisory locks and outbox retries, so a reward is never lost or paid twice.
- Shipped Trial Learning and Custom Curriculum end to end across 5 flows: guided speaking, scholarship scoring, student placement, bulk imports and progress tracking.
- Cut Pronunciation Evaluation latency by turning 3 sequential calls (Azure Speech, AWS S3, PostgreSQL) into 1 parallel step, and made recording recover from microphone failures.
