- Took ownership of the DevOps implementation for the project, mentoring a junior engineer, reviewing work, and setting technical direction while coordinating closely with project stakeholders. - Collaborated with dev team to migrate the development environment from Rancher 1.6 (Cattle) to Rancher 2.3 (Kubernetes), delivering more robust deployment capabilities and tighter access control. - Designed and implemented secrets management using SOPS integrated with AWS KMS, enabling encrypted configuration in Git and secure decryption during deployment via IAM-controlled access. - Established and enforced modern CI/CD standards across all microservices by implementing a common Jenkinsfile. - Drove operational efficiency using automated EC2 provisioning self-service portal (Jenkins/Boto/AWS CLI) for development team. - Proactive cost optimization through AWS infrastructure management activities (unassigned resources, tagging). - Streamlined branch naming conventions, repository management and port management. - Set up health and system metrics monitoring for Spring Boot services using Prometheus - Cloudera administration (Set up new cluster, troubleshooting issues, cluster monitoring). - Set up tooling infrastructure (GitLab, Rancher, RancherOS, Kubernetes and GlusterFS). - Provisioned and managed AWS infrastructure using Terraform with S3/DynamoDB as remote backend. - Automated startup of Appian components (Appian Service Manager, Search Server, Data Server and JBoss server) using Python. - Deployment automation using Python on AWS EC2 (Windows) & on-premise instances.

- Served as the technical lead within a 6-member team, mentoring junior engineers and guiding architectural and implementation decisions, while reporting into an engineering manager. - Established a dedicated Git repository to manage all build and deployment scripts, migrating them from unversioned Jenkins job configurations. - Achieved substantial workflow efficiency and standardization by developing a robust shell script that orchestrated the build and deployment of over 60+ components via Jenkins. - Executed the complex, large-scale migration of all repositories from Git (Gitolite) to GitLab, ensuring zero data loss and minimum downtime. - Secured and scaled artifact management by executing a major Artifactory upgrade and migrating Maven repositories to a new, high-performance hardware platform, concurrently integrating secure LDAP-based authentication for centralized access control. - Implemented automated daily Git merge activity in Jenkins.

- Enhanced script maintainability and ease of updates by converting several legacy Windows batch scripts to Perl. - Optimized build performance by componentizing and parallelizing a monolithic build, reducing build time significantly (80%) and enabling users to resume from a specific stage instead of starting afresh. - Provided build and deployment troubleshooting support.

- Streamlining build & deployment activities by defining and implementing formal processes and standards across the team. - Built the foundational automation capability using Hudson, streamlining the development lifecycle. - Managed the end-to-end lifecycle of Development and QA environments, including MySQL database administration (creation, backup). - Provided critical build and deployment issue resolution support. - Developed automation using Windows batch scripts to address flaky network issues for remote server synchronization (xdelta).

- Played a foundational role in defining the organization's initial Release and Configuration Management (CM) processes and standards. - Successfully set up and administered CVS and CVSNT from scratch as open-source version control alternatives to Rational Synergy (erstwhile CM Synergy). - Automated regular deployment activities to SIT, QA, and Production environments using shell scripts, improving repeatability and reducing errors. - Managed the release lifecycle (creation, maintenance, baseline) and provided basic administration for Weblogic server and legacy CM tools (Rational Synergy, Rational Change).
