I like software that is understandable, maintainable and grounded in real use cases.
Who am I
A Software Engineer focused on enterprise applications and integrations
Hi, I’m Aitzol Garro. I live in Zarautz, in the Basque Country, and I’m a Software Engineer with 8 years in tech, 6 of them building SAP Business One products and integrations with .NET, C#, TypeScript, Node.js and SQL.
Much of my professional experience has been connected to SAP Business One and the systems that integrate with it. I have worked on B2B integrations including EDI, Redsys payment flows and intercompany solutions, as well as web applications for configuring and managing these systems.
My career began in systems administration and evolved into software development. That combination has given me a practical perspective on applications, data, integrations and the infrastructure behind them.
Outside my professional work, I build personal projects with Astro, React and modern web technologies, exploring new ways to create maintainable web products and applications.

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.
