Back to original languageAbout Steven
Senior Software Engineer with ~10 years of experience in enterprise integration, backend development, and large-scale distributed systems. I specialize in designing and implementing critical integration platforms, with deep expertise in Apache Camel, Java/Spring, and hybrid on-premise/cloud architectures, connecting heterogeneous systems in some of the most demanding operational contexts.
Most recently at Rolex, I architected and operated integration systems deployed in 19 countries, processing over 10 million transactions per day, where reliability is not a luxury but a basic requirement.
Beyond the technical stack, I place great importance on pragmatic engineering: designing sustainable systems that teams can own and that solve real business problems rather than mere elegant abstractions. I work closely with architecture, product, and business teams to keep the technical vision and operational reality aligned.
Available for freelance enterprise integration missions: integration platform design, middleware migration, hybrid architecture, or DevSecOps support in complex and critical environments.
