Backend & business logic first
I build applications around real workflows: data, rules, integrations and maintainable backend architecture.
Fullstack engineer · backend, systems and product-minded development
I build robust software systems for real business use cases.
Fullstack engineer with 6+ years in enterprise environments around SAP Business One. I focus on backend development, system architecture and applications that have to work with real users, real data and real constraints.

Fullstack engineer with systems background
.NET / C# JavaScript SQL Infrastructure Solidity
I care about clarity, maintainability and building systems that make sense technically and from a product perspective.
What I bring
Technical depth with a clear product and delivery mindset
I am strongest when a project needs solid backend thinking, pragmatic architecture decisions and attention to the operational side of software.
Infrastructure-aware development
My systems administration background helps me design with deployment, reliability and operations in mind.
Exploring hybrid product ideas
I am currently experimenting with mobile + Web3 architectures without losing focus on practical product design.

About me
A technical profile shaped by systems, enterprise software and curiosity
I am based in Zarautz, in the Basque Country. I started from systems administration, moved into multiplatform development and today work as a fulltime software developer at Seidor.
That path gave me a practical view of software: architecture, backend logic, infrastructure, deployment and long-term maintainability all matter together.
Outside of day-to-day enterprise work, I like building personal projects that let me explore product design, mobile interaction and emerging technologies such as Solidity and Web3.
How I work
- • I prefer clear systems over flashy complexity.
- • I value maintainable code and understandable interfaces.
- • I like projects where technical decisions are tied to real product needs.
Next step
I am especially interested in work where backend architecture, product thinking and modern delivery practices come together.
