- Java
- Python (Pyramid)
- Apache Camel
- MySQL
- Redis
- Backbone.js
- Built Flight Search: aggregated internal module APIs via RestTemplate, cached results in Redis, implemented markup, pagination, filtering and sorting; built a Python (Pyramid) BFF layer normalizing data between the Backbone.js frontend and Java backend.
- Integrated the Jetstar seat map via NDC API for pre- and post-booking seat selection, orchestrated with Apache Camel routes.
- Reduced redundant airline API calls by reusing seat offers and re-fetching only when missing, expired or rejected, with automatic re-authentication.

- Handled seat booking failures (e.g. seat taken concurrently) by rebooking without the seat, so the booking still completed with a seat-fee refund.
- Fixed price discrepancies from a partner airline’s currency switch (LAK to USD) by remapping currency/region configs.
- Built Claude Code skills on the team’s AI rules to generate boilerplate and review code, speeding up seat map delivery.
