- Established CI/ CD pipelines using GitHub Actions and Jenkins, reducing deployment errors and rollback times to under 10 minutes.
- Built a nightly data synchronization service with FastAPI (Python), storing results in PostgreSQL and Elasticsearch to support reporting without impacting production traffic.
- Optimized PostgreSQL and MySQL performance using connection pooling, read replicas, and query tuning, reducing p95 latency under load.
- Applied Domain-Driven Design (DDD) and Clean Architecture when decomposing a growing monolith into smaller services, improving maintainability and developer onboarding.
