AI Solutions Architect

I design and build the systems a business actually runs on — and increasingly, the AI that runs inside them. The technology follows the problem, not the other way round.

What I do

01

AI workflows and automation

Manual processes — quoting, triage, reporting, document handling — rebuilt to run themselves, and to hand off to a person at the points where that still matters.

02

Company knowledge systems

Your documents, procedures and history made answerable, so a team asks a question instead of hunting through folders and asking whoever has been there longest.

03

Autonomous agents, integrated

Agents that do real work inside your existing systems — reading, deciding and acting through the tools your business already runs on.

04

Enterprise applications and integrations

The foundation the rest sits on: business software, APIs and integrations built to be maintained. Five years of it, mostly in the .NET ecosystem.

Projects

Most of my work runs inside companies and isn't mine to publish. I'm preparing a couple of pieces I can show — until then, the engagements above are the record.

About

I work independently with clients from Costa Rica, and I sell solutions rather than a stack. What the problem needs decides the technology: I've spent five years delivering enterprise systems — most recently logistics workflows in .NET — and I bring that engineering discipline to whatever a project actually calls for.

Lately that means AI, in two ways. I develop with AI end to end, which changes both how much one engineer can deliver and how quickly, and means I'm no longer bounded by the languages I happened to learn first. And AI can be part of the solution itself: workflows that run without anyone driving them, systems that answer questions from a company's own knowledge, agents that act inside the tools a business already uses.

To be straight about it, the AI work is where I'm investing now — built and proven on my own projects rather than shipped to a client yet. The engineering underneath it is not new; that part has five years of production behind it. If you have a process still running on spreadsheets and email, or a system that has outgrown the way it was first built, that's the conversation I want to have.

Let's talk about your project.

Tell me what you're trying to build, or what isn't working today. I'll reply with how I'd approach it — no obligation.
