I turn business requirements into clear technical logic — and I build them into real apps across Python, Node, Angular & Dart. Click any project below to open a live, playable demo.
I spent nearly two years as a System Analyst at SourceCode Co., Ltd. — writing API specifications, designing sequence diagrams, and turning messy business requirements into clear, buildable logic.
Now I build that logic into working software myself. Everything in my Projects section is a real program you can open and play with right here — backed by source code you can run.
Click a card to expand it — how I approach that area and the tools I reach for.
I read the business need first, break it into rules, states and flows, then capture it as specs and sequence diagrams the team can build against without guessing.
I build REST APIs the way I used to spec them — clear endpoints, validated inputs, correct status codes. Because I designed these systems before, the logic is already in my head.
I model data to match real-world relationships, query it with SQL, and turn raw CSVs into clear dashboards with pandas & matplotlib so people can actually decide things.
I build component-based UIs in Angular + Tailwind and mobile screens in Flutter, mapping each one to its API so front and back agree before build.
Five real programs I built, one per technology. Each card opens a pop-up with a working demo plus the source code (the runnable files live in the demos/ folder).
A native desktop GUI app — add, complete and delete tasks, auto-saved to JSON.
Reads a CSV with pandas and renders a 4-panel matplotlib dashboard. Try the live version.
A standalone Angular component with live search & category filtering, styled in Tailwind.
A full CRUD API. Fire real GET / POST / PUT / DELETE calls in the demo and watch the JSON responses.
A mobile todo app — add, check off and swipe-delete tasks. Play with it in the phone frame.
Happy to explain the logic behind any of these or build something new.
