The person behind the product mindset, code and curiosity.
I'm Jona, a software developer in Chile with over 8 years of experience, focused on mobile/web and on building clear, useful and well-crafted products.
I'm Jona, a software developer in Chile with over 8 years of experience, focused on mobile/web and on building clear, useful and well-crafted products.
I genuinely enjoy programming, solve problems and keep learning. I am always curious about how things work and interact, because that is usually where better solutions start to appear.
Outside of code, I recharge through video games, music, drums, anime, films and photography. All of that also shapes how I think about rhythm, detail and experience.
Professional track in constant evolution.
