I'm a passionate software engineer who loves technology, software, and backend development. I specialize in building robust backend systems using Java, Spring Boot, and PostgreSQL.
I'm currently building BeeL. — the Verifactu invoicing API for platforms, marketplaces, and multi-NIF SaaS. Think "the Stripe of Verifactu": you POST an invoice and we handle the hash chaining, signing, and AEAT submission so no one else has to.
Currently building: BeeL. — API-first Verifactu invoicing infrastructure.
- 🔭 Working with: Spring Boot, PostgreSQL, TypeScript & AWS.
