Independent AI product engineerBased in Thailand. Building everywhere.

Human instinct. Machine scale.

I’m Mack. I build AI products and native apps, and ship them: Full Circle, and ten iPhone apps on the App Store. I build the same way for founders and teams.

The AI team that
shows its work.

Full Circle gives a small online business a team of AI agents for its inbox, content and follow-ups. Every job comes back with proof: what was asked, what ran, who checked it and what it cost. Nothing goes out without your OK.

Out in the world

There’s an app for that.
Sometimes, I built it.

Ten apps, live on the App Store. Each one designed, engineered, submitted and maintained by me. Scroll the shelf.

Coming soon: Balance News, Sushi Empire and Sushi Express.

A different kind of builder

The tools keep changing.
Good judgment compounds.

I’m a software engineer with a product builder’s mindset. My work spans client projects, independent apps, and AI systems I use myself. I connect the technical possibilities to what people actually need—and take responsibility for getting it built.

Find the right problem.Make it feel simple.See it through.
Where I can help

What if
we built it?

For founders with a possibility.
For teams with a bottleneck.
For people ready to move.

Let’s find out

An idea is the beginning. I work with you to find the useful part, design the experience, and build the application around it. AI where it earns its place. Thoughtful software everywhere else.

Engineer. Maker. Curious human.

Hi, I’m Mack.

I like the space between
“what if” and “it works.”

I started in software engineering and freelance work, helping people turn ideas into websites and applications. Now I’m building with AI: products, agents, and the systems that make them useful.

The throughline is still the same. Understand the problem. Care about the experience. Build something worth using.

Based in Thailand, working with people around the world. When we work together, you work directly with me—from the first conversation to the last detail.
