What I'm looking for

I am looking for a role that fosters innovation, collaboration, and continuous learning in a supportive environment.

I am an experienced Senior Java Backend Engineer with over 18 years in software development, specializing in creating secure, scalable, and high-performance backend systems. My expertise lies in modernizing complex systems and building REST APIs using Java, Spring Boot, and cloud-native architecture on AWS, particularly within regulated financial services. I am passionate about test-driven development and clean code, and I thrive in collaborative, Agile environments.

Throughout my career, I have successfully designed and implemented cloud-native backend services, led teams through architectural transitions, and mentored junior engineers. My recent role at Capital One involved architecting a modern REST API framework and contributing to the migration of legacy systems to cloud-native architectures. I take pride in my ability to collaborate directly with product stakeholders and drive projects to successful completion while maintaining a focus on quality and performance.
