What I'm looking for

I'm looking to build scalable backend systems and APIs in agile, international teams, with opportunities to work on cloud infrastructure, event-driven architecture, and production-quality integrations.

I've built backend services, REST APIs, and GCP infrastructure for enterprise clients at First Solution, taking systems from design through deployment and production support.

I designed a concurrent-safe stock management system using atomic locking, DataStore queuing, and job scheduling, and built a CRM lead deduplication engine that reduced duplicate records by 90%. I also delivered an asynchronous webhook pipeline that achieved an 85% customer conversion rate for education clients.

Previously, I built financial APIs and PostgreSQL schemas for SNDQ and developed C# extensions for Microsoft Dynamics 365 at FPT Software. I also build a Node.js and NestJS ticket-booking platform with PostgreSQL, QR payments, and real-time check-in.
