At Jetstar Asia, I built React and Next.js interfaces for booking lookup, itineraries, service requests, and refund tracking. I also developed Python and FastAPI services and connected the portal to existing reservation and payment systems.
I designed PostgreSQL models for service requests and audit records, and added safeguards against duplicate submissions. I also added Pytest and Playwright coverage and automated tests and Docker builds in GitHub Actions for staged AWS releases.
At Kaodim, I cut median booking-search API latency by 42% through query profiling, indexing, Hibernate fetch tuning, and Redis caching. I also reduced routine deployment time from 45 to 15 minutes by automating Jenkins and Docker release workflows.
Earlier, at Honestbee, I built grocery ordering and fulfillment features and shortened a representative partner catalog import from 60 to 35 minutes. At GoBear, I built financial comparison features and reduced a frequently used comparison query from 1.2 seconds to 700 milliseconds.
