AI that actually ships.

I'm Loic, a full-stack engineer with 24 years of code behind me. I build AI automations and internal tools that save your team hours every week, delivered in weeks, at a fixed price.

Everyone talks about AI. Few teams actually use it.

You know AI could save your team time. But demos don't run your business, and hiring a full-time AI engineer takes months. Meanwhile, your people still copy data between tools, answer the same questions, and process documents by hand.

I close that gap. I find the work that eats your team's hours, then build the automation that removes it. Not a prototype: a working system, connected to the tools you already use.

Outcomes, not hours.

You pay for a result at a price agreed upfront.

Senior from day one.

No juniors, no hand-offs. You work directly with the engineer who builds it.

Built to last.

Clean code, documented, and yours to keep.

Three ways to work together

from $1,500/month

Fractional AI Engineer

A senior engineer on your team, without the hire. A fixed block of hours each month to improve what we built, add new automations and keep everything running.

  • Need more? 30 hours for $2,800/month
  • Monthly roadmap call
  • Priority support
  • Cancel anytime with 30 days' notice

audit from $400

App Rescue

Built your app with AI tools and now it's stuck? Bugs, security holes, slow pages, code nobody understands. I audit it, tell you exactly what's wrong, and fix it at a fixed quote.

  • Written audit within 5 days
  • Prioritized fix list with prices
  • Audit fee deducted if you go ahead with the fix

Things I've built

Demos coming soon. Ask me about past projects on our call.

Loic Ernult

Hi, I'm Loic.

I wrote my first line of code at 6. Twenty-four years later, I still haven't found a problem I didn't want to take apart. I've built across the whole stack: frontends, APIs, databases, infrastructure, and now AI systems that tie them together.

I started Lumizon to do the work I enjoy most: taking a messy, manual process and turning it into software that just runs. I work remotely from Asia with clients worldwide, which means your problem often gets solved while you sleep.

Questions

What if AI isn't the right fix for my problem?

Then I'll tell you on the first call. Sometimes a simple script or a better tool setup beats AI, and I'll recommend that instead.

Who owns the code?

You do, fully, once the project is paid. No lock-in.

What about my data and privacy?

I use your accounts and keys where possible, so your data stays in systems you control. Happy to sign an NDA before we start.

How do payments work?

50% to start, 50% on handover for Sprints. Monthly plans are billed at the start of each month. Invoices come from LUMIZON Ltd. (Hong Kong), payable by bank transfer.

What does it cost to run afterwards?

Usually a few dollars to a few hundred a month in AI and hosting fees, paid directly by you. I estimate this in the proposal.

Can you work with my existing developers?

Yes. I can build alongside your team, hand over cleanly, or review AI-generated code they've written.

What would you automate first?

Tell me the task your team hates most. In 30 minutes, I'll tell you whether it can be automated, roughly how long it takes, and what it costs. Free, no obligation.
