About Me
Hi, I'm Alejandro
Software developer — Java microservices & APIs
I'm a passionate software developer focused on building open source tools and sharing knowledge with the community.
I'm Alejandro, a software developer from Castellón, Spain. Since 2024 I've built and maintained Spring Boot microservices — modeling databases, documenting APIs, and working directly with clients. Outside of work I build open source projects — from native Android apps to developer tools — and share what I learn as a tech content creator. I speak Spanish (native) and English (C1), and I believe open software makes the whole community better: every project I publish is an invitation to collaborate, learn, and build together.
