Products I designed, built and run: WordPress plugins, WooCommerce stores, AI apps and web infrastructure.
macOS app for AI image upscaling and restoration that runs entirely on the Apple Silicon GPU: product shots, portraits, old family photos, wildlife, landscapes, illustration and screenshots. Text stays correct, Vietnamese included, with diffusion-based Recover and a CLI and local API for developers.
iPhone and iPad app for credit cards, loans and pay-later wallets, built for card holders in Vietnam: shared limits counted once, due reminders, on-device import of PDF statements, SMS and screenshots, offer-aware card advice and an AI assistant that only drafts. No account, no server.
A WordPress backup, restore and migration plugin. It packages an entire site with a standalone installer, runs on a schedule, ships archives to Local, FTP, SFTP or NAS storage, and restores on a new host without WP-CLI.
A WooCommerce storefront for PC hardware and prebuilt systems, rebuilt as a custom FSE block theme with Core Web Vitals tuning, an integrated PC configurator and real-time product sync from production.
A rebuild of the iga.vn gemstone store on a custom theme and plugin: collections by stone type, Five Elements stone matching, SEO-ready product copy, and an unchanged URL structure so rankings are preserved.
AI app for laptop review content: from one product link it produces true-to-device photo sets, spell-checked Vietnamese banners and voiced review videos with real benchmarks, all callable through a REST API for the article pipeline.
WooCommerce PC configurator plugin: wide configuration table, filterable part picker, compatibility checks, PSU wattage estimate, installment calculator, A4 quotes and shareable links.
A bilingual Next.js 14 portfolio with a custom MySQL-backed CMS, plugin documentation, a plugin update server and an MCP endpoint that lets AI agents query projects and docs.
Internal software for inventory, sales, purchasing, warranty, finance and accounting: an append-only ledger that is reversed, never edited, department-scoped permissions, encrypted backups and weekly restore drills.
