I'm a fullstack Software Engineer with 4+ years of experience building scalable microservices, high-value solutions for the financial, insurance, and fintech industries.
I specialize in backend development with Java, Spring Boot, and WebFlux, but I also work across the stack with Angular, Python, and cloud technologies.
I’m passionate about clean architectures (DDD, Hexagonal, SOLID), writing maintainable code, and continuous learning.
Currently based in Medellín, Colombia 🇨🇴. Cat lover 🐾 and self-taught enthusiast.
