With over 10 years of experience, I have designed, developed, and optimized scalable applications across healthcare, finance, and retail industries. I specialize in Java 21, Python, Spring Boot 3.x, PySpark, Hadoop, and JavaScript frameworks, delivering high-performance, secure, and scalable solutions At Cardinal Health, I led the development of a next-generation inventory management system, leveraging Java 21’s virtual threads for high-concurrency processing and OpenShift for containerized microservices. My work involved optimizing real-time data processing using PySpark, Hadoop, and Snowflake, ensuring seamless transaction validation and fraud detection. At Bank of America, I developed secure banking applications, integrating GraphQL APIs, Spring Boot 3.x microservices, and Kafka-based event-driven architectures for reliable financial data handling. I also implemented Python-based ETL pipelines to enhance reporting and compliance processes. At Target, I enhanced e-commerce platforms by integrating React, Angular, and Node.js, improving user experience and performance. I also worked on WebSphere Commerce and ATG-based solutions, optimizing backend services for high-traffic retail operations. I excel in microservices, API development, containerization with OpenShift, cloud solutions (AWS, Azure, GCP), Terraform-based IaC, and CI/CD automation, ensuring security, scalability, and efficiency in modern enterprise applications.
