Alber Cuenca

I’m a Backend Software Engineer with 2+ years of experience designing and building scalable, high-performance systems using Java and Spring Boot. I focus on REST APIs, distributed systems, and event-driven architectures, and I improve performance through caching, indexing, and asynchronous processing while prioritizing reliability with automated testing using JUnit and Mockito.

In my projects, I’ve built and maintained backend systems that measurably reduce latency and execution time, including API response time improvements of up to 35% and PostgreSQL execution time reductions of up to 40%. I also bring strong delivery and operations experience—designing CI/CD pipelines with GitHub Actions, deploying on AWS (EC2, S3), containerizing with Docker, and using logging and metrics for monitoring and observability in production.
