About Alberto

I'm a Senior Backend Developer specialized in building scalable systems in Go and Rust for high-traffic platforms.


At WebBeds, I work on backend services supporting a platform that processes 8.5B+ search requests and 9.9M bookings annually.

Previously, I built key modules for Esfera, a healthcare platform serving 350,000+ users across the Region of Murcia for the Murcian Health Service.

My focus areas include distributed systems, microservices, cloud infrastructure (AWS), and observability (Grafana, Prometheus, Datadog), with experience across HealthTech, Marketplace, Digital Marketing, and e-Commerce.


I enjoy working in fast-paced, remote, multicultural teams, and I'm always interested in connecting with other backend/infra engineers.
