What I'm looking for

I'm open to backend, platform, full-stack, and AI engineering roles in international remote teams, where I can build automation, modernize systems, and develop scalable technical foundations.

I'm building AI agents and MCP-based automation at 4set Talent & Technology, where Claude Code workflows cut JUnit test authoring from roughly two days to half a day per module and were adopted by a 15-developer team.

I deliver Java/Spring Boot REST services with React frontends, plus C++ and gRPC integrations for third-party real-time communications engines. I also ship Docker images and GitHub Actions pipelines, owning validation, merges, and releases.

Previously, I modernized COBOL and VB6 systems into Java and HTML5/Angular at Go4IT Solutions, and helped build webmail functionality for more than 500,000 registered users at Grupo Versia.

Alongside my work, I'm developing Plan Core, a TypeScript spatial computing platform connecting physical spaces, applications, IoT, automation, and AI through an extensible domain model and geometry tooling.
