Malaysia

Message

At Snappymob, I built the .NET 10 API integration layer for GBG Australia that translates customer requests into GBG Kleber requests while preserving the API contract. I completed the core logic in one month against a three-month plan, using Claude Code and validating it with xUnit tests.

I've also developed travel platform services and integrations with Amadeus, Sabre, and Travelport, and worked on SAP data integration for palm oil traceability. Earlier, I built web and Windows applications for energy monitoring and billing, and developed systems for newspaper production at Fujitsu.
