About
This is my personal website. I keep my study materials here and turn them into curricula, graded exercises, past exam papers, language practice and AI tools, for me and for other students. It is also where I build and ship real products. One developer designs, writes and runs all of it.

CT Work is on the App StoreRead for free, practise with real feedback. Everything is organised the way you would study: follow a path, practise until it sticks, sit a real exam paper, then use what you learned at work.
Content is counted, not estimated: the figures below come from the database, with the time of the count shown.
Type checks gate every deploy, which then smoke-tests the core routes before it counts as done.
This is my hands-on experience: products I designed, built, shipped and still run myself. Every link below goes to the real thing.
A Jira-style tracker for the projects students actually run: boards, backlog and sprints, docs, test reports in FPT University’s templates, meetings, team chat, and CuongMini, an AI assistant that knows the project. The iPhone and iPad app is native, and everything syncs live with the web and desktop.
One assistant in several places: AI Chat on the web, a coding agent inside VS Code and Cursor, a CLI for the terminal, and the Ask AI panel in CT Work. In code it reads, edits and runs commands, and asks before it acts.
Academy (FPT University subjects with slides, notes and exam practice), self-paced courses with video lessons, Code Lab with automatically graded exercises, real past exam papers, language learning and interview practice. Self-hosted on my own VPS.
The whole site as an Electron app for macOS, Windows and Linux. It updates itself from public GitHub releases and includes the AI Code tool that works on your own project folder.
A SwiftUI app synced with this site: study by major, handwritten notebooks on iPad, a book library.
A lab-room and equipment booking system (SWP391 → SEP490, FPT University), planned and run on CT Work with the process written up on this site.
I build modern web apps with Next.js, Node/Express and TypeScript on PostgreSQL, with AI features that actually ship — interview grading, CV critique, language tutoring. This whole platform is something I built and run myself.
This is my personal website. It began as a place to keep and organise my study materials and notes, and I turn them into courses and practice, for myself and for other students. It is also my workshop: where I build real products end to end and ship them, on the web, the desktop, iOS and as AI tools.
I would rather build the thing than go looking for it. The data schema, the API routers, the deploy pipeline — all written and operated by me on my own VPS.
Outside of coding, I write up the production incidents I have hit and how each was fixed — the part nobody can copy, and the part I learn most from.
Open to work, collaboration, or a question about anything on this site.
Anyone can list technologies. These are real failures on this site, what caused them, and what changed afterwards.
A deploy that synced code but did NOT rebuild: the container kept serving an old build that never mounted the GIF route. The chats were never lost — a per-viewer delete flag filtered them out.
Diagnose routes with an unauthenticated `curl`: 401 means mounted, 404 means stale build. Deploys now always rebuild and smoke-test the core routes.
Grouped by what they do. Tap one for the proficiency bar, what I actually know, and the real products that use it.
One VPS, Docker-managed, from the apps people open down to the database and the AI. Tap a product to open the real thing.
The studio takes on projects. Start with what it builds, then send a request.
