What I'm looking for

I seek senior engineering roles where I can lead cloud-native, secure full-stack development, mentor teams, modernize systems, and drive DevSecOps and agile delivery.

I am an accomplished Full Stack Java developer with 15+ years designing, developing, and maintaining scalable, secure applications across healthcare, government, insurance, and marketing industries.

I specialize in Java (Core and Spring ecosystem), building REST APIs, cloud-native microservices on AWS, and modern frontends using Angular and React. I drive CI/CD, DevSecOps practices, and production reliability through testing and monitoring.

I have led Agile teams as a Scrum Master/Agile Delivery Lead, mentored engineers, modernized legacy systems, and delivered measurable outcomes like a 60% reduction in process time through serverless workflows and significant infrastructure automation improvements.

I hold certifications including CSM, A-CSM, PSM I, SAFe Agilist, and PMP, and I focus on bridging business goals and technical implementation through servant leadership and solution-focused architecture.
