Full-stack developer from Portugal

I build quiet web products and practical business tools.

I'm a full-stack developer at Bomsite and a software development student based in Portugal. I work across Next.js, C#, ASP.NET, SQL Server, and product interfaces, building internal platforms, integrations, dashboards, and small personal tools like Luma.

Current direction
Minimal interfaces, useful systems, and reliable execution.

Work

Business apps, PHC workflows, dashboards, and integrations.

Product

Luma and small tools built around clear, practical use.

Taste

Calm visuals, precise copy, strong hierarchy, no noise.
