tl;dr version.

Based in Warsaw, Poland.

I have always had an entrepreneurial and curious mindset, that’s why I love coming up with digital products and constantly learning new stuff.

I started programming when I was 10. I’ve built 2D online game engines, social platforms, countless websites, business and marketing strategies...

I have worked extensively as a freelancer, collaborated with clients from many industries, and worked for agencies from different countries.

I have taken part in startup events and programs with my own startups and as a mentor to others.

I have mentored peers, educated clients, and helped companies shape and execute their goals.

“Guillermo is one of the most reliable person I have ever worked with. Apart of his technical skills as Developer and Product Engineer, he always has been involved in different topics that require soft skills (Recruitment, Technical Interviewer, Technical Challenges reviewer...). Always exceeding expectations :)”
