What I'm looking for

I seek senior engineering roles building cloud-native, secure API-driven systems with AI-assisted features, collaborative Agile teams, mentorship opportunities, and strong DevOps practices.

I am a Senior Full Stack Engineer with 15+ years building robust, scalable applications across healthcare, government, insurance, and marketing.

I lead backend-heavy, API-driven architectures using Java, Spring Boot, microservices, Kafka, and modern frontend frameworks like Angular and React to deliver secure, high-performance solutions.

I design cloud-native systems on AWS and GCP, implement CI/CD, and apply AI/ML techniques for automation, semantic search, and decision support while enforcing code quality and security standards.

I mentor engineers, drive Agile delivery, modernize legacy systems, and own architecture decisions that balance scalability, compliance, and operational observability.
