Top Projects

  • An Khang Land

    Real-estate agency site, catalog-only like the vehicle ones. Each listing carries area, bedrooms, aspect, floor or lot, furnishing, legal status and handover date; prices with no public figure read "contact for the price list". Each development also gets its own landing page — key figures, location map with travel times, on-site amenities, a per-unit price table pulled from the catalogue, payment stages, construction milestones and an enquiry form.

  • Ebooks

    A curated, community-contributed library of IT/CS ebooks spanning 39 topics — from algorithms and databases to AI, LLMs, and system design.

  • Map Timeline Visualizer

    A browser-based tool that turns Google Maps Timeline exports into interactive visualizations: animated route replay, heatmaps, trips, places clustering, calendar view, and a yearly recap — 100% local, nothing leaves your device.

  • Oggy Adventure

    A browser-based 2D side-scroller that teaches kids aged 5–10 while they play: guide Oggy through four learning journeys, collect book pages that unlock knowledge cards, solve quizzes to open gates, and beat Joey, Marky, Dee Dee and a boss in each area. Plain JavaScript on HTML5 Canvas with Web Audio synthesized sound — no build step, no libraries. Fan-made, non-commercial.

  • Portfolio

    Showcasing my projects and skills. There is also a blog section, where I write about my projects.

  • Showroom Ô Tô

    Car showroom in catalog-only mode: no cart or checkout. Prices read "contact for a quote" and enquiries go through a lead form. Listings show seats and body style.

  • Tiệm Bánh

    Bakery storefront. Made-to-order cakes show a prep-time notice; products carry shelf life, storage, servings, ingredients and allergen warnings.

  • UI/UX Design Guide

    Trang web tổng hợp kiến thức và kỹ năng UI/UX Design nổi bật trong năm 2025.

  • VIEvent

    Event ticketing platform: seat-map ticket selection, VietQR payments with automatic reconciliation, refunds and organiser settlements, plus an AI chatbot. Separate portals for customers, artists, staff and admins. Built with ABP 9.2 / .NET 9 and Angular.

  • x2mint

    A graduration project, which is a website for creating and taking tests online, made with MERN stack.

  • Đi Đâu Đây?

    Decision engine for local experiences in Vietnam, starting with Ho Chi Minh City. Answer a few questions and get one concrete suggestion in about 15 seconds, with directions and a shareable link. Next.js 16 static export — no database, no API, no auth; the data is static JSON validated with Zod.
