Available to hire
I have been developing computer software for more than 25 years and I still have fun every day. The fascination for computers and microelectronic systems has driven me since my childhood. I learn new technologies and ideas as a self-taught and pragmatic professional, embracing challenges with curiosity and practical mindset.
I am passionate about building robust software solutions that work across platforms, mentoring teams, and continuously improving processes to deliver value. I enjoy taking ownership, driving architecture decisions, and collaborating with cross-functional teams to create tangible outcomes.
