Taking new projects

Websites, automation and custom tools for small businesses.

I'm Vu, a Senior Software Engineer in Seattle with 10+ years of building for the web, and your site handyman. I build websites that bring in customers, automate the busywork that eats your week, and make custom Chrome extensions and web apps, from big builds to small fixes. I work with businesses anywhere in the US over Zoom and email, in English or Vietnamese.

What I can do for you

If you've ever thought "there has to be an easier way to do this," that's usually where I come in.

Websites

A fast, good-looking site that works on phones, shows up on Google, and turns visitors into calls and bookings.

  • New sites and redesigns
  • Booking, menus, quote forms
  • Google Business & SEO basics

Automation

If you do it by hand every week, it can probably run itself, with you approving the steps that matter.

  • Invoices and billing runs
  • Spreadsheets and reports
  • Data entry between tools

Chrome extensions

Custom tools that live in your team's browser and add the buttons your software is missing.

  • Private tools for your team
  • Public Web Store extensions
  • Updates to existing extensions

Web apps

Customer portals, internal dashboards and MVPs, from first sketch to launch, with code you own.

  • Accounts and payments
  • Admin dashboards
  • AI features, done carefully

Automation & apps

Web app · Supabase, Postgres, works on phones

Order management for a home kitchen

A family catering business ran on one overgrown Google Sheet. Now an order takes a few taps, the 70-dish menu with photos goes out to customers as a link, and receipts, customer history, expenses and monthly profit are always at hand. Bilingual (Vietnamese and English), multi-account from day one, and backed by 52 automated tests.

Automation · runs every month

Rental billing on autopilot

A monthly chore that used to take hours: pull four utility bills, split them between two units, post the charges, update the ledger and message the tenants. Now it runs by itself on the 10th, and I approve four checkpoints along the way. The same pattern works for invoicing, reporting and data entry in any small business.

Web app · Next.js, Postgres, installable on phones

AI chat app with subscriptions

A complete product, not a demo: sign-up and login, a chat that remembers context, paid plans with checkout and cancellation, data export and account deletion, an admin console, and safety rules that route people in crisis to real help. It's backed by 64 automated tests.

How it works

Simple, from first call to launch

Build with weekly demos

Launch and handover

About

One engineer, start to finish

After graduating from the University of Washington, I've worked as a Senior Software Engineer at a tech company in Seattle. I handle work up and down the stack to build web applications with a world-class user experience.

Outside of work, I build things. Since 2015 that's been Chrome extensions, Android apps, a real-time chat app, browser games, and lately AI tools and automations. My own rental business runs on software I wrote.

When you hire me, you get the same engineer and the same standards, and you talk directly to the person writing your code. No account managers, no hand-offs. I'm based in Seattle and work with businesses anywhere in the US, in English or Vietnamese.

FAQ

Common questions

I'm not in Seattle. Can we still work together?

Yes. I work with businesses anywhere in the US. We meet on Zoom, and everything else happens over email.

Can we talk in Vietnamese?

Yes. I speak both Vietnamese and English, so we can meet, write the quote and build your site in whichever you prefer, or in both.

Who owns the website or code when we're done?

You do. The code, the domain and the accounts are in your name. I hand over everything with short docs so anyone can maintain it later.

What if I'm not sure what I need?

That's what the free call is for. Describe the manual version: the clicking, the copying, the spreadsheet. I'll tell you honestly whether it's worth building, and roughly what it would cost.

How does payment work?

Payment is split into milestones that we agree on in the written quote, so you never pay for work you haven't seen.

What happens after launch?

You can call me when you need something, at $100/hr, or pick a monthly care plan from $150/mo that covers updates, fixes and small changes.
