PROFESSIONAL SUMMARY

I'm a passionate Java Developer who loves building scalable, high-performance applications across IT, banking. With expertise in Spring Boot, Hibernate, and Jakarta EE, I specialize in designing micro services architectures on AWS and Azure, ensuring systems are efficient, secure, and future-ready. I enjoy working with RESTful APIs and GraphQL, especially when it comes to enhancing EHR/EMR interoperability using FHIR, HL7, and DICOM—helping healthcare systems exchange data seamlessly. I’ve also built real-time data streaming solutions with Apache Kafka and NiFi and optimized ETL workflows and database performance across PostgreSQL, MySQL, MongoDB, and Azure SQL. Security is a top priority in everything I build. From OAuth 2.0, JWT, and RBAC to encryption protocols, I ensure compliance with HIPAA, PCI-DSS, and SOC 2 standards. I also have hands-on experience with Docker, Kubernetes, and CI/CD automation using Jenkins, GitHub Actions, and Azure DevOps, streamlining deployments for smoother, more reliable releases. Beyond coding, I love solving complex challenges, collaborating with cross-functional teams, and turning raw data into actionable insights with Power BI, Tableau, and AWS QuickSight. I thrive in Agile environments, always eager to learn, adapt, and build impactful software solutions that make a difference.
