Summary
🤩
Rockstar🎓
Top SchoolÒscar Casajuana is a CTO/CEO and full-stack DevOps engineer with 16 years building web apps, microservices and SOA infrastructures from Barcelona. He co-founded Underave and led platform architecture at Cirici, designing CD pipelines and running containerized services with tools like Docker, Traefik, Consul, Vault, GitLab CI and Kubernetes while shifting teams from CakePHP sites to React-based microfrontends. Hands-on across back-end, front-end and ops, he contributes to CakePHP localization, OpenComponents and framework docs—often improving locale validation, linting and build processes. Comfortable administering Linux servers and scripting deployments, he pairs entrepreneurial initiative with deep practical experience delivering production systems and documentation. A less obvious strength: he blends product-minded design involvement with low-level validation fixes, showing both user-focus and attention to locale-specific correctness.
