At Littlelives, I build secure school operations workflows and multi-tenant payment services with Node.js, TypeScript, and PostgreSQL. I launched DBS and OCBC Bank Giro collection and refund integrations.
I replaced a timing-out PostgreSQL query with a CTE-based approach that brought it under 100 ms, and maintained 100% data integrity during production migrations and parallel-run validation.
At Grof, I took a corporate card platform from an empty repository to production within 12 months. I established automated CI/CD practices and helped grow the engineering team through mentoring.
Earlier, I delivered healthcare applications at Bithealth and integrated secure mobile banking workflows at Multipolar Technology. At TDI, I supported a bank clearing process, after beginning my career in operations at Charoen Pokphand.
