Hi, I’m Juan David Garzón

Backend-focused Software Engineer passionate about building reliable, scalable, and secure applications. I enjoy solving complex problems, continuously learning new technologies, and creating software that delivers real value.

About Me

I’m a backend-focused software Engineer who enjoys transforming ideas into reliable and maintainable software. I like understanding how systems work behind the scenes and building applications that are clean, scalable, and designed to solve real-world problems.

I enjoy taking on challenging problems and researching until I find the best possible solution. I’m a fast learner who adapts quickly to new technologies and environments, and I believe continuous learning is one of the most important qualities of a software engineer.

Throughout my professional experience, I’ve often taken responsibility for guiding, training, and supporting teammates. I enjoy helping others grow, taking ownership of my work, and contributing to a collaborative environment where challenges are solved together.

My backend stack includes Kotlin and Spring Boot, while I continue expanding my frontend skills with React, Next.js, and TypeScript. I’m also experienced with PostgreSQL, Docker, REST APIs, Git, and modern development workflows, and I enjoy applying secure development practices throughout the software lifecycle.

My long-term goal is to specialize in backend engineering, mobile development, DevSecOps, and AI security. I’m passionate about understanding the complete software lifecycle-from designing and developing applications to cloud deployment, and secure software practices-and I hope to contribute to the development of intelligent systems and robotics throughout my career.
