About Me

Hi, I’m John-Alvin, a Full Stack Developer specializing in Ruby on Rails. Coding truly fuels my soul, and the thrill of continuous learning is absolutely addictive! Driven and constantly seeking to deepen my knowledge, I thrive on embracing new challenges. My interest in cybersecurity, particularly penetration testing, informs my approach to building more robust and secure applications that solve real-world problems.

I value clear communication and actively seek opportunities to share insights and connect with fellow developers. Explore my projects on GitHub and follow my programming adventures and learning experiences on my blog. Beyond professional development, my hobby in game development broadens my creative problem-solving skills.

When not coding, you’ll find me engrossed in a good book 📚 or exploring new recipes in the kitchen 🔪.
