What I'm looking for

I’m looking for remote roles worldwide.

At PT Robust Creative Media, I deliver full-stack work across client platforms, taking features from database schema through production interfaces. I built a FinTech PPOB transaction engine integrating the Digiflazz provider API, with webhook handling and idempotent retries to prevent duplicate balance changes.

I’ve also built warehouse stock allocation workflows using PostgreSQL transactions and row-level locking to prevent stock discrepancies during concurrent orders. I work across NestJS, TypeScript, and PostgreSQL on the backend, and Next.js, Vue.js, and Nuxt.js on the frontend.
