About Me

Team Lead and senior developer with 7 years in enterprise software and over 15 prior years in business and customer-facing roles.

At MinIT I lead a team of 3-5 people and coordinate daily with colleagues across Europe and India, fully remote, for leasing and mobility clients: Arval, Athlon (Spain, Italy, Portugal, UK, Belgium and Sweden; now part of Arval) and Santander Leasing Sweden.

I design REST APIs to integrate systems and build CI/CD pipelines with GitHub Actions and Azure DevOps (build, Docker images and environment deployments), taking each release from hours to minutes.

My sales background gives me something uncommon in a technical profile: I understand the client's business and turn it into solutions that work.
