Summary
🤩
Rockstar🎓
Top SchoolJoseba Ayesta is a Staff Engineer with over 20 years designing and building secure, high‑performance embedded and server-side software for demanding domains like payment processing, tolling, transit and smart cities. He blends deep Java expertise—from JVM tuning, bytecode manipulation and Java Agents to OSGi, Spring and JEE—with practical skills in DevSecOps, IAST/RASP and OWASP-driven application protection. As former CTO/Software Architect at Hdiv Security he helped create frameworks that harden web apps and REST APIs and contributed to Spring HATEOAS and OWASP projects, demonstrating a rare mix of product-minded security engineering and low-level systems craft. He’s experienced across the stack and lifecycle—CI/CD, performance tuning, stress testing and embedded hardware integration—and has led architecture for international, large-scale deployments (Metro Madrid, Sydney Harbour Bridge, Tianjin Metro, MOPAC). Based in Bilbao, he combines hands-on troubleshooting (jmap/jstack/JProfiler) with architectural leadership, often solving concurrency and resource-constrained performance problems that are easy to overlook.
