Built it with AI? I'll get it to launch.

AI built your app in a weekend.Now every change breaks something else.

I'm the senior engineer who takes your AI-built app the rest of the way. I audit it, fix the architecture, build it out, and leave your team able to run it.

From vibe-coded to launch-ready.

A senior human who takes it all the way

Twenty years shipping production software. When an AI-built app stalls, the cause is rarely one bug. It is the architecture, the data, the security, and the people and process around it. I work across all of it and stay hands-on, building with AI under senior judgment.

  • Senior and hands-on.

    Two decades in production. I architect and build it hands-on, AI-assisted, and the fix holds.

  • Full stack, past the code.

    The technical work, and also the people, the systems, and the compliance that turn a prototype into a real product.

  • You keep the keys.

    Once the base is solid, I show your team how to build with AI well, so you own it rather than depend on me.

Start where you are

  • Audit

    Is it safe to launch? A production-readiness audit of your AI-built app, across security, data, and architecture. You get a plain report and a ranked fix plan.

  • Rescue

    Make it production-grade. I fix the architecture and rebuild the weak parts, so it stops breaking every time you touch it and it can take real users and real payments.

  • Fractional

    Stay on and level up the team. Once the base is solid, I work alongside you as a fractional technical lead and coach your team to build with AI without recreating the mess.

Beyond the app work, I also build and run websites for established businesses whose site is starting to fall behind as the way people search keeps changing.

With AI now spinning apps within minutes, whoever figures out distribution will own the game.

Three years all-in on AI-assisted engineering.

That’s a two-year head start on the mainstream. In the 2025 Stack Overflow survey, only 31% of developers were using AI agents.

recommendations

  • The build was a huge success and was completed in less than 8 months. The deployment and data-transition was performed without any issues and we went live during the busiest period of the year.

    Marius Du Toit — Founder at Mantisse Software

  • Alex is a supremely talented software engineer. He sees the big picture, unlike most people I've worked with - leadership included. Vision. Strategy. Team dynamics. P&L.

built around what couldn't move

A merchant-facing payment layer built on infrastructure that was already running and couldn't be changed. An existing switch, thousands of terminals in the field, and a PCI surface to keep small. The goal was to introduce a new, improved architecture without anyone noticing the transition.

the humans behind the systems

A spin-and-win campaign for a major South African telco, built in three weeks for millions of subscribers and live for five years. The integrations were the easy part. The real challenge was connecting the people behind the systems...
