Top SchoolArturo Bernal is a pragmatic technical lead and senior software engineer with nearly two decades of experience building and scaling Java backends, specializing in resilient, low-latency Spring Boot services and production deployments on AWS and GCP.

As an Apache PMC and committer, he helps steer HttpComponents’ evolution—keeping APIs spec-compliant, secure, and high-performance—and contributes steady, quality-focused fixes across many flagship Apache libraries. Known for pragmatic refactoring, performance tuning, and making CI/CD “boring,” he mentors teams to ship predictable, observable systems. Based in Antwerp, he pairs deep technical craftsmanship with governance experience and an MBA-informed sense for prioritizing work that reduces operational risk.
