- Owned end-to-end security and reliability work on an undocumented Django production app: identified and fixed a critical flaw (inbox encryption using symmetric instead of asymmetric), and completed a stubbed password-health/breach-detection feature to production.
- Built the company's first automated test infrastructure (Pytest + Playwright/TypeScript) from scratch, covering auth, vault management, sharing, and team workflows — now being adopted for a second production project.
- Delivered full-stack improvements across security (MFA/recovery flows), data handling, and UI, working independently with no formal handover.
I'm an Informatics Engineering graduate focused on building scalable data pipelines and production-ready backend systems — with hands-on experience across the full stack from ingestion to deployment.
I design ETL workflows, transform large datasets, and build the backend systems that support them, including authentication, testing, and CI. My work spans data ingestion, transformation, and orchestration, as well as Django applications, automated testing (Pytest, Playwright), and production pull requests.
Recently, I completed the Data Engineer Professional Certification, working with tools such as Airflow and logging systems, strengthening my understanding of workflow orchestration and pipeline monitoring.
Currently working as a Software Engineering Intern at Valuedate.io, and open to Data Engineer, Software Engineer, Test Automation, and AI Engineering roles — remote worldwide or hybrid in North Portugal.
