Work Experience:

• I have Been worked as a Lambda-ENi-Management service which Developed and Managed ENI functionality for Aws lambda service by developing java application for CRUD API call for multiple regions across the internal and external AWS accounts.
• Utilizing ENIs to enable high-performance communication between instances, allowing seamless data transfer and efficient application deployments.
• Implementing network segmentation and security by attaching ENIs to specific subnets and applying Security Groups to control inbound and outbound traffic.
• Leveraging ENIs to create multi-homed instances with multiple private IP addresses, facilitating versatile networking configurations and reducing operational complexity.
• Utilizing ENIs in scenarios where advanced networking features such as Network Address Translation (NAT), VPN connections, or Elastic IP addresses are required.
• Troubleshooting and resolving connectivity issues related to ENIs, ensuring uninterrupted network access and resolving any performance bottlenecks.
• Collaborating with cross-functional teams to design and implement complex network architectures utilizing ENIs, VPCs, and other AWS networking components.
• Configuring and managing ENIs within Amazon Virtual Private Cloud (VPC) to establish secure and reliable network connections for EC2 instances.
• Support and automate monitoring for the ENI management service for customers using cloudwatch
  monitoring and scale the API requests limit per usage load metrics.
• Worked alongside customers to resolve their issues with AWS Lambda deployment, which in-turn
  increased the deployment efficiency by 10%.
• Developed and maintained CI/CD pipelines using Jenkins, automating the build, testing, and deployment processes.
• Leveraged Java programming skills to develop and optimize applications for performance and scalability.
• Collaborating with cross-functional teams to design and implement complex network architectures utilizing ENIs, VPCs, and other AWS networking components
• Troubleshooting and resolving connectivity issues related to ENIs, ensuring uninterrupted network access and resolving any performance bottlenecks.

My proficiency in managing ENIs, combined with a comprehensive understanding of AWS networking services, positions me as a valuable asset in designing, deploying, and maintaining secure and scalable cloud infrastructures.

Projects:

• Led the migration of an on-premises application to AWS, implementing a scalable architecture with EC2 instances, S3 for data storage, and RDS for database management.
• Implemented a Kubernetes cluster for a microservices-based application, utilizing deployment strategies like rolling updates and blue-green deployments.
• Automated the CI/CD process for a web application, reducing manual effort and enabling frequent releases with increased reliability.
• Designed and implemented a logging and monitoring system using CloudWatch and the ELK Stack, facilitating real-time analysis and troubleshooting.
• Participating in an on-call rotation schedule, ensuring 24/7 availability for addressing critical network incidents and troubleshooting issues related to ENIs.
• Responded promptly to alerts and notifications, investigating and resolving network connectivity problems, performance degradation, or security concerns.
• Conducted root cause analysis (RCA) and post-incident reviews to identify underlying causes and implementing preventive measures to avoid similar incidents in the future.
• Documented incidents, resolutions, and lessons learned to maintain a knowledge base and enable efficient troubleshooting for future incidents.
• Proactively monitoring network performance, conducting capacity planning, and making recommendations for scaling or optimizing ENIs to support evolving business requirements.
• Participating in change management processes, reviewing proposed network changes, and assessing potential impacts on ENIs and overall network infrastructure.
• Provided guidance and support to team members, sharing knowledge and best practices related to ENIs, network troubleshooting, and incident response.

By effectively fulfilling on-call duties for ENI management, I have contributed to maintaining reliable and secure network connectivity, minimizing downtime, and ensuring uninterrupted service availability for critical applications.

• Designed and implemented automated deployment pipelines using Jenkins and Ansible, resulting in a 50% reduction in deployment time and improved overall system reliability.
• Managed AWS infrastructure, including EC2 instances, S3 buckets, and RDS databases, using Infrastructure as Code principles with Terraform, resulting in increased scalability and reduced manual configuration efforts.
• Led the adoption of containerization using Docker and Kubernetes, reducing application deployment time by 75% and enabling easy scaling and orchestration of microservices.
• Developed and maintained monitoring and alerting systems using tools such as Prometheus and Grafana, ensuring proactive identification and resolution of performance and availability issues.
• Collaborated with development teams to improve the build process and implement automated testing using tools like JUnit and Selenium, resulting in a 40% decrease in the number of production defects.
• Implemented security controls, such as IAM policies and network security groups, to ensure compliance with industry best practices and regulatory requirements.
• Provided technical guidance and mentorship to junior team members, fostering knowledge sharing and professional growth within the team
