FULLSTACK ENGINEER · 8+ YEARS

I build web and mobile products end-to-end.

Eight years in. Right now I'm building Tenantly, a multi-tenant website builder, for a US company. I reach for boring, proven tools over clever ones.

SELECTED WORK

Things I've built

Eight products I shipped or rebuilt. Some solo, some leading a team of four to ten.

Tenantly

Multi-tenant website builder I'm building on Laravel for a US company.

Problem: Small businesses want their own sites without touching code, and the company needed to run thousands of them from one codebase.
Approach: Building the multi-tenant Laravel backend — tenant isolation, billing, a Vue editor — with a publishing pipeline that pushes sites to the edge on Cloudflare. I picked Laravel because the team already knew it; a faster stack nobody could maintain wasn't worth it.
Result: Runs ~1,200 tenant sites today, and a new site goes live in under 30 seconds.

Steady — Habit Tracker

Solo-built React Native habit and sobriety tracker, live on the iOS App Store.

Problem: I wanted a habit and sobriety tracker that didn't feel like a to-do list. So I built one.
Approach: Designed and built the whole app solo: habit creation, streak logic, milestone badges, and auto-renewing subscriptions through Apple In-App Purchase.
Result: On the App Store with ~4,000 downloads and a paying subscriber base, all built and shipped by me.

Precinct

US voter-information platform for finding legislators, candidates, and results by precinct.

Problem: Voters can't easily find precinct-level information on legislators, ballot candidates, and election results in one place.
Approach: Maintained and extended the platform through its 2.x cycle — added SMS and email alerts for seat changes and election timers, and rebuilt the subscription tiers.
Result: Shipped a three-tier model (Free / State $9/mo / National $99/mo), migrated the infrastructure, and cleared the stability bugs across the release cycle.

Threadline CRM

Full-stack CRM with unified email and social messaging plus a companion mobile app.

Problem: Sales teams need email and social messages in one CRM, on web and on mobile.
Approach: Built it on Next.js, Supabase, and GCE; wired up Gmail and Facebook APIs for unified messaging; shipped a React Native companion app; instrumented with Segment and Sentry.
Result: Delivered the messaging and mobile features in a five-person cross-functional team.

Kaizen Sport — Eligibility Wizard

Youth-athlete eligibility tool with reporting and automated NCAA updates.

Problem: Managing youth-athlete eligibility and NCAA status meant heavy manual analysis and updates.
Approach: Led a four-dev team to re-architect the app on Next.js and Tailwind, built charting with PDF export, and added a React/Node email and SMS notification system.
Result: Cut data-analysis time by 30% and manual NCAA updates by 50%.

Wizzer Training

Training-course site rebuilt for speed with a 10-plus-person team.

Problem: A content-heavy training site was loading too slowly on web and on mobile.
Approach: Built it on React and Node.js with asset optimization, lazy loading, and code-splitting, and automated training reminders through GCP.
Result: Cut web boot time by 80% and mobile load time by 30%.

Transore Storefront

Go storefront API rewrite for a Shopify-based platform.

Problem: The storefront API was slow and had to keep up with Shopify market changes.
Approach: Rewrote the storefront API in Go, built market-insight and redirect features, and migrated the platform onto new Shopify markets.
Result: Cut loading time by about 30%.

Landing Page Service

Conversion-focused landing pages wired to ad campaigns and analytics for multiple clients.

Problem: Clients running Google and Meta ads needed fast landing pages plus the hosting and tracking to measure them.
Approach: Built and deployed landing pages across client accounts, ran the hosting and server infrastructure, and set up analytics and conversion-tracking pipelines.
Result: Shipped 20-plus campaign pages across multiple clients with end-to-end hosting and conversion tracking.

ABOUT

How I work

I'm a Vietnamese fullstack engineer, eight years in. I work remotely for a US company, building Tenantly, a multi-tenant website builder. I've shipped web and mobile apps the whole time, solo and in small teams.

I'm comfortable across the whole stack, backend and frontend, and I'll work with whatever a project already runs on. I pick boring tools on purpose. A framework the whole team already knows beats a clever one I'd have to explain at 2am. Lately a lot of the work is wiring AI APIs into products that still have to work when the API doesn't.

Based in: Vietnam
Working with: Web & mobile, backend to frontend
Open to: Senior fullstack roles, contract or full-time
Languages: Vietnamese (native), English (fluent)

HOW I CAN HELP

Three ways I get pulled in

Most work I take on looks like one of these.

Ship a new product

Empty repo to something real users can pay for. I've taken an app to the App Store solo, so I know which corners are safe to cut early and which ones page you later.

Rescue an inherited codebase

Slow, fragile, the code nobody wants to touch. I stabilize it, add the tests and instrumentation it never had, and make it safe to ship again.

Add AI to a product

Wiring LLM and other APIs into features that hold up, with fallbacks for when the API is slow, down, or just wrong. The demo is easy. The reliability is the job.

GOOD TO KNOW

The practical stuff

What recruiters and clients usually ask first.

Where are you based?

Vietnam, GMT+7. I work remotely with teams across US and EU hours.

Are you available?

Open to senior fullstack roles, contract or full-time. I reply within a day.

How do you work?

Remote and async-friendly. Happy owning a feature end-to-end or joining an existing team.

What about English?

Vietnamese is native, English is fluent. Not native, but it's never been the bottleneck.

CONTACT

Tell me what you're building.

Best for client work, contract roles, or a question about anything I've shipped. I reply within a day.
