I’m Abby Henríquez Tejera, a Senior Full-Stack Engineer & Systems Architect based in Dublin, Ireland with 15+ years building distributed systems, cloud-native infrastructure, and scalable web applications. My focus spans Ruby, Scala, Java, JavaScript/TypeScript, Linux systems, containerisation, and microservices, and I thrive in fast-paced environments where robust architectures and maintainable code matter. As a former Engineering VP who stays hands-on, I enjoy shaping technical strategy, mentoring teams, and delivering both greenfield solutions and complex migrations from monoliths to microservices for high-traffic contexts. I’m comfortable bridging core platform concerns with delivery, balancing feature velocity with reliability, and evangelizing cloud-native best practices across teams.
