What I'm looking for

I'm seeking a role that values collaboration, innovation, and continuous learning.

I'm a seasoned full-stack software engineer with more than twenty years of hands-on experience across the full software development lifecycle (SDLC). My expertise lies in designing and building scalable Java/Spring Boot microservices, REST APIs, and Angular-based web applications in cloud environments, particularly AWS. I have a proven track record of leading technical initiatives, mentoring team members, and collaborating across departments to deliver business-critical solutions.

In my most recent role at Shutterfly Business Solutions, I developed and maintained scalable Java Spring Boot microservices supporting enterprise clients, enhancing system scalability and resilience through AWS migration. I engineered Kafka stream integrations for event-driven processing and designed an internal reporting tool that significantly improved operational visibility. My previous experience includes leading modernization efforts at Lincoln Financial Group, where I refactored a large monolithic Java web app into microservices, resulting in improved performance and reduced costs.
