I designed the backend for Investment Tracker, a multi-broker investment platform, using Next.js, TypeScript, and PostgreSQL. I implemented role-based Row Level Security and built 540 automated tests with Vitest and Playwright.
For Code Duel, I designed a modular Java and Spring Boot backend with isolated code execution in Docker containers. I also implemented real-time communication with WebSocket, JWT authentication, and matchmaking.
I designed Aula AlDía as a multi-tenant education platform using Django and Django REST Framework, with tenant-level data isolation and configurable plan quotas. Its React frontend included layered route guards and token renewal designed to prevent duplicate requests.
In my IT Technical Support role, I resolved weekly support incidents, managed access through Active Directory, and developed and maintained internal web portals. I’m studying Systems Engineering at Universidad de Santander and have also built a Java process scheduler using Clean Architecture, JUnit, and performance benchmarks.
