I build web and mobile products end to end: Next.js/React and Flutter on the front end, Node.js, NestJS and Go on the back end. I’ve spent two years on FWD’s insurance platforms, and as a freelancer I’ve shipped commerce, CRM, fintech and edtech products for clients in Vietnam.
A marketplace for Ngoc Linh ginseng with garden care, consignment trading, real-time chat and QR bank-transfer payments.
An elevator sales system with role-based CRM, orders, revenue and KPI tracking, sales check-ins, and a public catalog site powered by the CMS.
A multi-channel digital lending platform: one API serves web, Flutter and Zalo Mini App, with OTP, KYC, credit assessment and an admin console with audit logs.
A booking, ordering and POS platform for ZBOX sleep-box branches: a Next.js customer website plus three Flutter apps (customer, cashier POS, manager) handle boxes, sessions, product checkout and revenue reports, and a Go backend syncs activity to the main system. Shipped to the App Store and Google Play.
A ride-booking system with a Flutter customer app including KYC, a Flutter admin app, and a NestJS content service with RS256 JWT auth, media upload and Docker deployment.
An English learning app for Vietnamese learners on web and mobile: quiz-game lessons, an AI speaking room, flashcards, placement and IELTS/TOEIC tests, study roadmaps and Free/Plus plans.
