What I'm looking for

I seek a cloud-first, security-conscious team role where I can lead full-stack microservice development, optimize performance, and mentor others while delivering scalable, compliant systems.

I am a Senior Java Full Stack developer with 5+ years delivering scalable, secure enterprise solutions across healthcare, finance, and telecom. I specialize in Spring Boot microservices, cloud-native architectures (AWS, Azure, GCP), and front-end frameworks like React and Angular.

My experience includes building OAuth2-secured REST APIs, event-driven pipelines with Kafka and RabbitMQ, and automating infrastructure with Terraform, CloudFormation, Kubernetes, and CI/CD (Jenkins, GitHub Actions). I have improved ETL and data workflows using Python, Spark, and Airflow, reducing processing times and improving operational efficiency.

I thrive in Agile teams, mentor peers, and focus on reliability, performance, and compliance (HIPAA, PCI, OWASP). I deliver end-to-end solutions from UX to backend, ensuring secure, maintainable, and high-performance systems.
