A place for ideas about software, product, technology, and where they’re heading.
About me
I’m a product builder who likes complex systems, ambiguous problems, and getting close to the technology. I’ve always been curious across disciplines, which is probably why my path has moved through design, product, software development, and even philosophy and economics.
How I got here
I started in graphic communication design, where I learned to research and appreciate things like typography, spacing, visual balance and semiotics. From there, around 2010, I gradually moved into software, first building websites with WordPress, and then building complete web applications.
I co-founded Book&Learn in 2015. It became my first opportunity to build a product from scratch: figuring things out with limited resources, learning by doing, and eventually leading technology in a startup. In 2020, Book&Learn merged with Edvisor, giving us an exit and opening the door to a new set of challenges.
At Edvisor, I went much deeper into product, developed more technical rigor, and moved between different roles as the company and the problems changed: from delivery and product management to technical leadership and Product Engineering.
I’ve also kept a long-running interest in philosophy, economics, technology, and sociology, mostly out of curiosity.
Where I’m going
Right now, I’m spending a lot of time building with AI and trying to understand what it changes: in software, in product development, and in general in the society. I’m particularly interested in how we can navigate this shift in a way that extends what people can do rather than simply replacing what they do.
I’m also starting a Master’s degree in AI applied to finance to build a stronger technical foundation and take this work further.
