This is me: Crafting next-gen systems for a connected tomorrow.

With 20+ years in software engineering and a solid foundation in tech leadership, I create next-gen systems for our accelerated culture. I focus on scalable architecture, automation, and elegant developer experiences.

I believe AI is the defining technology of our time. It’s not a trend, it’s the new infrastructure. I help companies embed intelligence into their products and processes, turning data into decisions and software into strategy.

Elixir is my tool of choice when it comes to building resilient, scalable, and maintainable systems. Its elegance, fault-tolerance, and focus on concurrency make it the ideal language for the future-facing infrastructures I design.

When I’m not building systems, I tell visual stories through photography and lead immersive tabletop adventures, where world-building, strategy, and narrative come together. Creativity fuels everything I do, from imagined realms to real-world code.
