The person behind the work

Engineering depth. Human perspective.

I'm Antonio, a senior software engineer and independent consultant. My work spans AI, backend systems, cloud platforms, and industrial automation. I enjoy untangling hard problems, making sound technical choices, and helping teams deliver with confidence.

My stack. I build across the whole stack, end to end. My deepest expertise is in Elixir, Go, and TypeScript, and I'm very proficient in plenty of others.

Languages open doors. I work in English, German, French, Italian, and Croatian. That helps me connect people within a business and across organisations, and turn different perspectives into shared progress.

Industry experience

Years spent in the field, not just on paper.

Many years of hands-on experience, from industrial automation through AI-native software. I have shipped real systems, led teams through difficult rebuilds, and delivered results that hold up in production.
