António worked on the NIAEFEUP/enei and NIAEFEUP/nitsig repositories, delivering features that improved reliability, data integrity, and developer experience. He expanded backend and admin panel capabilities using TypeScript, JavaScript, and AdminJS, introducing license management, relational data models, and enhanced referral metrics. António established reproducible development environments with Nix Flakes and streamlined onboarding through consistent tooling. His frontend contributions included a dynamic tab navigation system in React, improving UI navigability. He also maintained repository hygiene by standardizing configuration files and lockfile formatting. Across both projects, António demonstrated depth in backend, frontend, and DevOps, focusing on maintainability and scalable data handling.

May 2025 — NIAEFEUP/nitsig: Delivered a non-functional cleanup to the flake.lock lock file to enforce formatting consistency, without changing behavior or dependencies. The change reduces future churn, simplifies diffs, and improves maintainability. Demonstrated disciplined version control practices and attention to detail in repository hygiene.
