Problem Solver First

Beyond specific technologies and software, I consider myself a 'problem solver' first and foremost. I aim to focus my solutions on achieving tangible outcomes and real-world value. At the same time, coding is my greatest hobby; I frequently work on personal projects driven by a curiosity to research and explore new tools. In my portfolio, you will find a blend of both facets. Furthermore, whenever possible, I will create technical blog posts detailing my projects at a low level, complete with code snippets. Ultimately, I build solutions that matter while continually exploring the technology I am passionate about.

Who I Am

I'm a simple person who likes to stay active and curious. I really enjoy sports and going to the gym, and I consider myself a lifelong amateur because I'm always trying new disciplines. Over the years I've practiced activities like climbing, boxing, taekwondo, kickboxing, and rugby, among others, always with the idea of learning something new and staying active. I'm also a bit of a movie lover and I rarely miss the chance to watch a film at the cinema. Programming is another important part of my life: it's not only my job but also a hobby that I often pursue outside working hours, experimenting with ideas, personal projects, and learning new things. And of course, I also enjoy anime; maybe a bit of a cliché in my field, but I guess I'm a product of my environment.
