What I'm looking for

I’m looking for an Agile team where I can grow into Python & AI while building reliable back-end services—REST integrations, business rules, clean code, and CI/CD—using my OutSystems strengths to deliver quality within scope and deadlines.

I’m a results-driven technology professional with 10+ years of experience in technical support and software development, delivering high-impact solutions across national and international projects. I have deep expertise in Low-Code Development with OutSystems (Mid-Level/Pleno), covering back-end logic, business rules analysis, REST API integrations, and Agile delivery via Scrum, Jira, and Azure DevOps.

I led business rules elicitation and technical documentation with technical and non-technical stakeholders, enforcing clean code practices through code reviews, branch management, and CI/CD pipelines. Today, I’m undergoing a strategic transition into Python and Artificial Intelligence—supported by recognized technical certifications—bringing a data-driven problem-solving mindset to building reliable, performance-focused systems.
