Hi, I'm Luis Ángel 👋

Backend Developer · Java & Spring Boot · Computer Engineer

About me

Backend developer focused on building clean, maintainable REST APIs. I enjoy designing systems that are easy to scale and reason about.

  • 🎓 Computer Engineer — Universidad de Guadalajara (CUCSUR)
  • 🔧 Currently deepening my knowledge in Spring Boot 3 & system design

Featured project

🏥 MediTrack — Medication Reminder System

A full-stack medication management system built around a production REST API.

Layer Tech
Backend API Java · Spring Boot 3 · JWT · Spring Data JPA · PostgreSQL
Web App HTML · CSS · Vanilla JS
Mobile App Kotlin · Retrofit · AlarmManager · WorkManager
Deploy Render (HTTPS)

Key highlights:

  • Stateless auth with JWT (access + refresh tokens) and role-based access control
  • Automatic scheduler that marks missed alarms and deactivates expired configurations
  • Android app with exact alarms, full-screen notifications and background sync every 5 min
  • Two user roles: Patient and Caregiver, with weekly adherence statistics
