Professional profile

Software developer with more than 15 years of experience across mobile, web, and applied AI.

My experience started long before my first job: at age 12 I was already programming in Basic and Pascal, then in C and Assembly. At 20 I developed an operating system kernel based on what I learned from Andrew S. Tanenbaum. Today I work in applied research with LLMs, agents, and AI tools, alongside mobile and web development to take solutions from prototype to production.
