Hi 👋, I'm TienNHM
Backend developer from Vietnam 🇻🇳
✍ Software developer at Utop @ FPT. I write about .NET, databases and system design at tiennhm.io.vn.
📝 Writing
A technical blog in Vietnamese — mostly production bugs I hit at work, traced down to the actual cause, with the experiment that proves it.
📘 .NET Backend: Zero to Senior
A free, structured course in five stages: C# foundations → professional C# → ASP.NET Core → databases in production → senior engineering.
