I am a software developer, sailing around the world.

About Me

About Me

Over the past 8 years, I've immersed myself in the world of software development, crafting interactive websites, intuitive mobile applications, and innovative data processing solutions. Yet, it's not just my code that defines me – it's my deep commitment to a sustainable future.


Aligned with my values, I live aboard my sailboat, navigating the oceans while staying connected to the digital world. This approach enables me to minimize my ecological impact while working on projects that truly matter. I believe that only software that promotes responsible usage, delivers value to customer and avoids overconsumption deserves to be created.


Passionate about the social impact of technology, I seek collaborations with like-minded individuals. If you share my vision of software development that prioritizes quality over quantity, I would be delighted to connect.


Join me on this journey where responsible software development meets a sustainable lifestyle, for a more thoughtful and eco-conscious digital future.
