Resolved bugs and implemented fixes at the Apigee policy level to enhance API functionality and reliability. Developed and implemented new features in Jenkins pipelines, enabling the selection of lower environments for testing and deployment. Addressed vulnerabilities and security issues in APIs by updating or removing outdated libraries to ensure compliance and robustness. Set up CloudWatch for monitoring and alerting across all Lambda functions and API Gateway endpoints. Implemented custom CloudWatch metrics to track critical application performance indicators (e.g., memory usage, execution duration) and designed alerts to notify the team of potential performance bottlenecks or failures. Integrated advanced log monitoring using CloudWatch Logs and Splunk. Enhanced troubleshooting by setting up detailed log aggregation and analytics workflows to ensure fast root cause analysis, reducing incident response time by 40%. Incorporated full-stack observability with Dynatrace, providing end-to-end visibility into Lambda function execution, API Gateway requests, and DynamoDB interactions. Used distributed tracing and real-time monitoring to identify and fix performance bottlenecks, leading to a 25% improvement in application response time. Managed serverless application deployment using the Serverless Framework, optimizing Lambda layers and package sizes to meet AWS size limitations. Improved code deployment processes and reduced bundle size by restructuring dependencies, leading to a more efficient deployment pipeline.

Ensuring software quality through testing and code reviews. Implement automated testing frameworks for improved efficiency. Adhere to quality assurance processes. Implementing and maintaining CI/CD pipelines. Automate build, testing, and deployment processes. Setting up monitoring tools and systems to continuously track the health and performance of services running on the cloud. Configure alerts to notify for any anomalies or deviations from expected behavior, enabling proactive intervention.

Helping for software-related issues internally and externally. Collaborating with customer support teams to resolve complex problems. Ensure high levels of customer satisfaction. Proficient in creating Bash scripts to automate routine tasks and streamline operations, significantly reducing manual intervention and enhancing efficiency.

Managed enhancements, customer bugs, and Root Cause Analysis (RCA) for the Automated Maintenance Window (AMW) module within the infra-core team of the EPM application. Facilitated the integration of native cloud EPM to Oracle Cloud Infrastructure (OCI), involving tasks such as VM creation, load balancer configuration, database management, VM image updates, shape modifications, and provisioning management. Utilized a combination of Java, Terraform & shell scripting to implement infrastructure automation tasks and ensure smooth operation of the AMW module. Designing and implementing systems with built-in fault tolerance and resilience mechanisms to minimize service disruptions in case of failures or unexpected events. Actively participated in root cause analysis efforts, contributing to the development of various reports including trend reports, SAR analysis, and other required reports to enhance system reliability and performance. Employed technical skills in Terraform, Docker, Tomcat, Java, Unix, shell scripting, REST, and Git to support the infrastructure and application needs of the EPM module within the infra-core team.

Implemented various combinations of solutions, including integrating different databases with replicators, to meet specific project needs and optimize system performance. Evaluated and selected appropriate technologies and methodologies to address complex requirements, ensuring compatibility and scalability of solutions. Managed highly escalated customer issues, addressing critical concerns and resolving technical challenges to ensure customer satisfaction and maintain positive relationships. Engaged with customers proactively to understand their concerns, provide timely updates, and deliver effective solutions that meet their expectations. Leveraged expertise in Java, TCL script, Shell script, and Unix to develop and deploy solutions, automate tasks, and troubleshoot issues effectively.Utilized scripting languages and Unix-based tools to streamline processes, enhance system.
