Profile

I have 17 years of professional experience as a seasoned Cloud Application Architect based in Chennai, Tamil Nadu, India. I specialize in open-source technologies such as OpenShift, Kubernetes Engine, Quarkus, Spring Boot applications, and Docker implementations. With over eight years of experience in application modernization, I have successfully migrated more than eight applications to Amazon Web Services (AWS), enabling CloudWatch, Prometheus, and Grafana Monitoring along with alert creation. Additionally, I possess expertise in creating CI/CD pipelines using Tekton and GitLab, integrating AWS with tools like Veracode and Prisma for dynamic application security testing (DAST), static application security testing (SAST), and image vulnerability scanning. My strong background in full-stack projects allows me to provide end-to-end solutions for clients looking to transition their workloads to the cloud. Furthermore, I am proficient in Terraform scripting, Oracle, Postgres databases, Struts, AngularJS, and have hands-on experience working with both AWS and Google Cloud infrastructure. Utilized ChatGPT, Instruct Lab, Neo4j, Granite Gen AI model to facilitate the conversion of legacy banking processes to align with BIAN standards.
