About

I'm Tran Nguyen Dang Huy (call me Huy) from Ho Chi Minh, Vietnam — a Backend Developer with 1.5+ 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 maintain the internal @nova/* package suite (Metadata Engine, auth, NVH) powering the group's ecosystem, built the ERM module and eOffice Sync pipeline, and integrated Microsoft OIDC SSO for the identity service.

Maintain the internal @nova/* package suite (Metadata Engine, auth, NVH, OAuth server) adopted org-wide — extend, patch, and harden shared modules consumed by other teams.
Integrated Microsoft OIDC SSO (web + mobile) and OAuth client-credentials flow into the identity service; extended the Meeting Check-in flow with face verification.
Built the ERM module (AES-256-GCM encrypted customer data ingestion), eOffice Sync (bounded-memory pipeline handling hundreds of thousands of rows), and the FCM push notification 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.
