When I'm Not Coding

I consider my pursuit of excellence to be my strongest skill. I believe in reaching the highest possible level in everything I do - not just in my professional work, but in all aspects of my life. This dedication to continuous improvement and mastery drives me in both my career and personal interests.

🎮

Gaming

Passionate about competitive shooter games like Valorant, Counter Strike, and Marvel Rivals. In 2022, I was part of an amateur Valorant team that won 2 competitive cups, teaching me teamwork and performance under pressure.

🐕

Dog Training

Training my Border Collie mix, Hermes, is incredibly rewarding. His intelligence pushes me to be the best tutor, turning every mistake into learning. I aspire to test our partnership with a BH test in IGP sport.

🎵

Music

Started learning electric guitar at 16 because I love challenges. My journey focuses on covering songs from Metallica, Pantera, and Guns N' Roses while continuously improving my skills.

⌨️

Keyboards

During lockdown, I started custom keyboards, exploring switches, keycaps, and layouts. Currently using a Corne keyboard with Dvorak layout to avoid strain injuries.

🍳

Cooking

Growing up with exceptional cooks set my taste standards high. When cooking for myself, I had to learn properly. Cooking is like programming - experimenting and iterating. My specialty is Chilean empanadas.

Coffee

My favorite drink is the latte, and I'm passionate about latte art. During lockdown, I dove into coffee culture, focusing on perfecting milk steaming techniques and creating beautiful patterns in my cups.
