I like software that is understandable, maintainable and grounded in real use cases.
About
A fullstack engineer shaped by systems, enterprise software and curiosity
Hi, I’m Aitzol Garro. I am based in Zarautz, in the Basque Country, and I currently work full-time at Seidor building applications in the SAP Business One ecosystem.
My path started in systems administration and evolved into multiplatform development. That combination gives me a practical view of software: backend logic, architecture, deployment and maintainability all belong to the same conversation.
Alongside enterprise work, I keep building personal projects to explore mobile product development, self-hosting and hybrid architectures involving Solidity and Web3.

My trajectory, represented as a Git repository
This is the most representative way to explain my path: education as the foundation branch, work as the main line, and current Web3 learning as an active exploratory branch. Each commit can be expanded for more detail.

How I work
A short human summary
I enjoy building software that feels solid under the surface. I’m less interested in chasing noise, and more interested in designing systems that are clear, useful and maintainable.
That usually means balancing technical structure with practical delivery: understandable code, coherent interfaces, and architecture decisions that serve the product instead of complicating it.
My systems background makes me think beyond code: deployment, reliability and lifecycle matter too.
I enjoy projects where architecture decisions support both technical quality and product clarity.
