Santhosh Thoddin Sathyamurthy

Cloud Architect | HCLTech

• Led the architecture and execution of a large-scale cloud migration, successfully transitioning 80+ microservices from OpenShift (OCP) to Google Cloud Platform (GCP), ensuring a seamless production cutover with minimal downtime.
• Currently driving application modernization initiatives by transforming legacy applications into cloud-native microservices architectures, enabling improved scalability, maintainability, deployment agility, and operational efficiency.
• Designed scalable, secure, and highly available cloud platforms on Google Kubernetes Engine (GKE), incorporating cloud-native design principles, infrastructure automation, and enterprise CI/CD practices.
• Defined migration strategies, application onboarding approach, dependency analysis, risk assessments, and rollback plans to ensure reliable and low-risk migrations.
• Collaborated with application development teams to modernize workloads, containerize applications, and adopt Kubernetes best practices for cloud-native deployments.
• Architected and implemented Infrastructure as Code (Terraform) and CI/CD pipelines using GitHub Actions, Azure DevOps, and Jenkins to standardize infrastructure provisioning and application deployments.
• Built and optimized Jenkins-based automation to provision and decommission on-demand test environments, significantly improving resource utilization and reducing cloud infrastructure costs.
• Modernized the enterprise test automation platform by migrating it to GCP, improving execution performance, scalability, reliability, and integration with CI/CD pipelines.
• Led production migration and cutover activities, coordinating with cross-functional teams including development, QA, infrastructure, networking, security, and business stakeholders to ensure successful releases and business continuity.
• Implemented monitoring and observability solutions using Prometheus, Grafana, and Splunk, enabling proactive monitoring, faster incident detection, and improved platform reliability.

• Automated the deployment and configuration of cloud-based applications, reducing deployment time by 60% and minimizing human error
• Implemented cloud-based security best practices, resulting in a 30% reduction in security incidents and ensuring compliance with industry regulations
• Collaborated with development teams to implement CI/CD pipelines, resulting in a 25% reduction in deployment time and a 15% increase in deployment frequency
• Develop and maintain scripts and tools to automate cloud-based operations
• Worked closely with development teams to improve deployment automation, release processes, operational stability, and cloud adoption across multiple application teams.
• Contributed to cloud architecture decisions, platform standardization, security best practices, and cost optimization initiatives to build scalable and resilient enterprise platforms.

• Played a major role in improving the deployment process by automating the end to end deployment of all components of application and efficiency has improved because there is less human error
• Developed shell scripts, designed and developed Urban Code for the automation of deployment process for three different applications, reducing the deployment time by more than 60%
• Played a major role in planning, designing and implementing the migration of a critical payment application from Solaris 10 to Solaris 11 OS
• Development of Control-M jobs to support the batch processing of payment applications
• Collaboration with various stake holders during the change implementations in production

• Played the lead role in managing environments for a group of critical applications for CME GROUP, an investment bank
• Managed deployment of code and patch releases into various environments (ST/SIT/UAT/QA)
• Supported Performance & Volume testing and Failover & Recovery testing
• Identified areas which required process improvement
• Automated the environment heath checks for a group of applications with the help of shell scripts, sql queries and Control-M batch jobs, which resulted in major effort savings

• Involved in gathering the requirements from the stakeholders on setting up the network for transmission of files
• Working on various tools for creating a secure environment necessary for secure transmission of files
• Testing the set up on the Test environment and implementing the same on production after successful testing

• Played a key member in managing critical applications for an investment bank (Duestsche Bank) in production
• Proactively monitored application processes, identified enhancements, root cause analysis for bug and development requirements
• Providing end user communication for critical issues like service delays/disruptions with ETAs
• Daily application health checks are performed before the start of the business day so that the application runs smoothly
• Handled user queries related to reports, batch processing (SOD/EOD Control-M jobs) and providing solutions within the specified SLAs
• Participated in deploying the code changes in production by following the run book prepared by the delivery team
• Provided operational support to end users for administration access, profiles and passwords, resulting in satisfied internal customer base
