My background

I'm a telecommunications engineer with a master's in electronic systems. I started very close to the metal, designing circuit boards and writing firmware, and worked my way up from there: microservices, real-time data platforms and cloud systems with hundreds of thousands of users.

I have worked as an employee for companies in industry, energy and education, and since 2025 as an independent consultant in phone support, online learning, restaurant software and digital agencies. I get up to speed quickly with each business because the underlying problems are similar: data that needs moving, processes that need automating and systems that cannot fail.

Today I focus on applied artificial intelligence: voice and text agents, documents, search over a company's knowledge and models on its own servers. I know AI from the inside and I know how businesses work; that double perspective is what lets me propose the most viable solution in each case, and one that keeps working after the demo ends.

How we work

  • Start small and measure

    A focused pilot with a clear goal before any large project.

  • Technical honesty

    If AI doesn't make sense for your problem, we'll tell you, even if that means the project doesn't happen.

  • Your data, under your control

    Privacy and security built in from the design stage, not bolted on at the end.

  • Maintainable systems

    Everything documented and defined as code, so it doesn't depend on a single person, not even on whoever built it.
