About Long
Full-Stack SaaS Developer | Next.js, NestJS, PostgreSQL
Ho Chi Minh City, Vietnam - 8:40 pm local time
I'm a full-stack software engineer focused on Next.js, TypeScript, NestJS, and PostgreSQL. I build and improve production web applications across the frontend, API, database, and integration layers.
I can help with:
- Next.js / React product features and dashboards
- NestJS / Node.js REST APIs
- PostgreSQL data models, migrations, and business logic
- Authentication, RBAC, validation, and CRUD workflows
- Third-party API and webhook integrations
- Debugging and improving existing applications
- Automated testing, Docker, and maintainable handoff documentation
Relevant work:
- StockPilot — multi-tenant inventory and B2B order operations SaaS built with Next.js, NestJS, Prisma, and PostgreSQL
- Tenvyr — automation/orchestration system involving API-based execution and callbacks
- Vietnamese Family Tree — Next.js + Spring Boot + PostgreSQL application with complex relationship logic, secure sharing, and automated testing
Professionally, I work on production Next.js systems at Lumin, including frontend delivery, CMS/API integrations, debugging, reliability, analytics, and observability.
I work best with clear scope, reviewable milestones, and direct communication. If you have an existing product or a defined feature that needs to be shipped reliably, send me the current stack and scope and I'll tell you how I'd approach it.
