About

I’m Gabriel Alves, an Informatics Engineering graduate who enjoys end-to-end development across full-stack, backend systems, and data engineering. I’m comfortable taking projects from an undocumented codebase to a merged, tested, and production-deployed feature, with strong priorities around quality, security, optimization, clean code, and delivery speed.

During my SEIT internship and related work, I built and shipped a privacy-first desktop app, helped fix and validate production security issues, and created automated test infrastructure from scratch using Pytest and Playwright (including TypeScript-based utilities). I also contributed to data and machine learning pipelines such as a customer churn prediction workflow, and I enjoy using tools like Copilot, Claude, and Cursor as a support layer while relying on my understanding of the codebase to deliver reliable results.

Work experience

SEIT Intern | Fullstack Engineer (and Data Engineer focus) · ValueDate.ioJun 2026 – Sep 2026 · 4 mos

Owned end-to-end security and reliability improvements on a production Django app with a fully documented, production-deployed feature. Identified and fixed a critical flaw in box encryption by correcting the use of symmetric vs asymmetric encryption. Completed a stubbed password health/breach-detection feature and shipped it to production. Built the company’s first automated test infrastructure from scratch (Pytest + Playwright/TypeScript), defining a reusable testing methodology and structure reused across two production projects. Improved security and reliability (including MFA/recovery flows), backend logic, data handling, and UI/UX, including delivering a reactive filter redesign that removed full page reloads, with handover and team enablement by running walkthroughs for continued adoption.

SEIT Intern (Full Stack / Backend / Data Engineering) · SEITJun 2024 – Sep 2026 · 2 yrs 4 mos

Owned end-to-end security and reliability work on an undocumented Django production app. Identified and fixed a critical issue related to box encryption using symmetric instead of asymmetric cryptography, and completed a stubbed password health/breach-detection feature to production. Built the company’s first automated testing infrastructure from scratch (Pytest + Playwright with TypeScript), defining a reusable testing methodology and structure adopted across two production projects. Delivered full-stack improvements across security (MFA/recovery flows), backend logic, data handling, and UI/UX, including proposing and driving a reactive filter redesign to remove full page reloads; worked independently and delivered clean handover.
