Senior🎓
Top SchoolJavier Sigler is a Senior Software Engineer based in Madrid with 11 years of experience building high-performance, production-grade back-end systems and cloud services. He has led large engineering efforts—owning architecture, code quality, and mentorship—for platforms managing millions of devices and dozens of microservices, and now contributes at Auth0 by Okta. Technically fluent in Java (incl. Java 8), Vert.x, Netty, gRPC, Redis, RabbitMQ and containerized deployments, he blends pragmatic engineering with SOLID-driven design to keep systems readable and maintainable. As a former Cloud Architect at BBVA Next Technologies he guided the evolution of 16+ Go microservices and defined platform strategy across on/off-prem data exchange. Javier pairs hands-on coding (from protocol-level servers to CI/tooling migrations) with team development and 24x7 production ownership, a mix that surfaces in operationally robust releases. He also draws on advanced studies in AI and computer science to inform practical architecture decisions beyond typical backend expertise.
