Support mindset. Builder energy. Quality focus.
I’m PHI HÙNG, a software engineering builder who enjoys working where technology meets real-world workflow problems.
My IT support background taught me to notice the things that slow people down: repetitive steps, scattered information, unclear processes, and fragile workflows. I turn those observations into practical software with a focus on clarity, maintainability, usability, and reliability.

Open contribution visuals
- Improving ScheduleWork into a smoother and more reliable scheduling system.
- Building practical software for real operational workflows.
- Growing deeper in frontend engineering, backend systems, testing and automation.
- Turning technical knowledge into products people can actually use.
If a workflow feels repetitive, I’ll probably try to automate it.
