Senior backend engineer specializing in scalable Java services and AWS infrastructure, focused on clean architecture.
SpainWhat I'm looking for
I’m a Senior Software Engineer with 10+ years in backend development, specializing in scalable Java services and cloud infrastructure. I’m passionate about clean architecture, mentoring, and building resilient systems that stand up to real-world complexity.
In Amazon’s Author Central ecosystem, I led a website revamp that simplified backend architecture and reduced technical debt. I reduced website build time by 80% using advanced WebPack configuration, redesigned onboarding authorization for stronger security and data privacy compliance, and supported teammates through design discussions and code reviews.
I also owned and improved systems that directly impact operational performance—like inventory mapping services across EU fulfillment centers and a configuration service that reduced setup time from weeks to days. I automated updates to cost-saving sourcing parameters to improve decision-making for logistics teams.
Earlier in my career, I built and automated core product workflows, including an internal loan lifecycle system with billing, interest, and overdue handling. I’ve also developed tooling for software generation from UML diagrams (producing full-stack CRUD web apps with tests and CI setup in under 30s) and delivered custom billing and deployment automation, including .NET tool support and PL/SQL modules.
