Previous role

  • • Developed MES/MOM features in C# and VB (.NET): work orders, traceability, batch execution, quality checks, and shop-floor data capture.
  • • Built maintainable back-end components, SQL data models, and interfaces supporting real-time operations and auditability.
  • • Applied standards and best practices (ISA-95/ISA-88, clean architecture, testing, CI/CD) to ensure reliability and ease of change.
  • • Collaborated with operations, QA, and automation teams to translate production requirements into software that is observable, supportable, and safe to deploy.

Sobre mi

I'm a Tech Lead leading development and delivery of complex software systems for global industrial clients across Europe.

I focus on taking ownership of hard problems and earning trust — both within the team and with the clients we work with.

My interest is in where technology and business strategy meet: making sure what we build actually moves the needle for the people who use it.

Beyond the technical side, I'm involved in presales and internal training and knowledge-sharing across teams — because great technology only matters if you can communicate its value.

Currently building toward a broader leadership role.
