IT Support gave me the habit of finding the real problem first. I bring that mindset into software engineering, QA, automation, and every product I build.

CURRENT FOCUS
Building tools that make real workflows clearer, faster, and easier to maintain.
I am Phi Hung. My day-to-day support mindset is simple: understand what the user is trying to do, find where the workflow breaks, and make the next attempt easier.
That naturally pulled me deeper into software engineering. I build web apps, desktop tools, APIs, scheduling systems, and experiments that connect real operational needs with practical code.
I care about readable interfaces, edge cases, permissions, testing, and maintainability — not only whether a feature works once.
Reproduce the problem, isolate the cause, then fix the workflow instead of masking the symptom.
Prefer small useful tools, clear states, sensible defaults, and feedback users can understand.
Happy paths are not enough. I actively look for awkward cases, conflicts, permission issues, and failure states.
WEB APPLICATION
A workforce scheduling platform where employees submit availability and admins review constraints, build conflict-aware schedules, publish the official week, and export it.
DESKTOP APPLICATION
An offline weekly scheduler with drag-and-drop assignment, split shifts, conflict detection, staffing summaries, and high-resolution schedule export.
AI / COMPUTER VISION
A CNN-based recognition project using the GTSRB dataset with image prediction, webcam inference, preprocessing, and model evaluation.
FULL-STACK WEB
A booking project for browsing routes, checking schedules and seat availability, and making reservations through a React client and REST backend.
Building responsive products and lightweight internal tools.
Connecting product logic, APIs, authentication, and persistence.
Packaging tools, working across systems, and shipping changes safely.
Finding edge cases, reproducing bugs, and keeping the user workflow visible.
Find the repeated friction, confusing step, manual workaround, or support pattern.
Turn the problem into the smallest useful feature, tool, or workflow improvement.
Test real scenarios, awkward inputs, permissions, edge cases, and failure states.
Use feedback to reduce steps, improve clarity, and leave the code easier to change.
I enjoy practical software, support-driven improvements, QA, automation, and learning by building.
