How I can help

My software solutions

I specialize in delivering high-quality software solutions across embedded, backend, and frontend environments, tailored to various domains. While I'm proficient in multiple programming languages, including C++, C#, Java, Kotlin, Rust, and Python, I'm adaptable and ready to work with whatever technology best suits your needs.

Software development

I build high-quality software products, working as an  engineer, architect, and tech-lead. Whatever role is needed to get the job done.


I love helping others get the best out of themselves. Whether it's individual coaching, mentoring, or training an entire group. I offer a set of fixed training programs as well as tailored courses to fit your needs.

20 years of experience in the software industry

I've worked with clients in various industries, including printing, semiconductors, automotive, and home automation. Interestingly, I don't have a strong preference for any specific domain. As long as it involves software engineering, and people.

Curious about the possibilities?

Let's get in touch to see how I can help you.
