About

Hello! I’m Kelvin Orozco Rodríguez, a junior full-stack developer focusing on Django and Angular. I bring about 6 months of production experience at a growth-stage technology company, where I optimized backend performance and resolved critical services impacting 30+ users. I’m known for practical problem-solving, Agile collaboration, and rapid learning, delivering high-impact solutions.

I’m the National Champion of WorldSkills Costa Rica 2025, and I’ve recently mastered Flutter in two sprints, building a mobile app that integrates with the 4Geeks API and JWT authentication using Clean Architecture. I’m excited to continue growing my skills and building reliable, scalable software with a focus on quality and collaboration.
