About

I'm Tran Nguyen Dang Huy (call me Huy) from Ho Chi Minh, Vietnam — a Backend Developer with 2+ years of experience building production-grade systems, currently at Novagroup.
Core stack: NestJS and Golang for microservices, PostgreSQL/MongoDB for data, Redis for caching, and RabbitMQ for async messaging.
At Novagroup, I designed a metadata-driven entity framework powering the group's ecosystem, published internal @nova/* packages consumed by other teams, and shipped Microsoft OIDC SSO plus AES-256-GCM-encrypted integrations for sensitive customer data.

Designed a metadata-driven entity framework (Metadata Engine) from scratch — dynamic CRUD, DDL migration builder, GraphQL schema sanitization.
Maintained the internal package suite adopted org-wide; extended the auth package with pluggable hooks for custom auth logic.
Shipped Microsoft OIDC SSO (web + mobile) and OAuth client-credentials flow for service-to-service auth.
Built the ERM module (AES-256-GCM encrypted customer data ingestion) and eOffice Sync, a bounded-memory pipeline handling hundreds of thousands of rows.
Built FCM push notifications and a face-verification check-in system; standardized production deploys (Vault + SSH Docker) across services.

Architected core microservices (API Gateway, Core, File Service) in Golang + Gin via RabbitMQ, handling 60%+ of backend load.
Improved API response times by 40–50% for high-traffic platforms (King Coffee, FlyFood, Eproshop) through caching and index tuning.
Open-sourced a reusable OAuth2/JWT SSO module to Packagist, standardizing security across 5+ internal systems.
Shipped backend services for Vietnam Food Map (Next.js + NestJS/Golang) with GraphQL and AWS Bedrock GenAI integration.
Mentored junior developers on clean architecture and code review; recognized twice for technical impact.
