• Designation : Snr IT Architect (AWS Cloud, SRE and Devops)
• Summary : Worked for the client who produces an electromechanical access solution. The application is running from containerized environments, such as EKS (Kubernetes), ECS along with other monolithic applications across 13 AWS accounts and 170 Servers etc.

Current project achievements and day to day roles.

• Worked as an independent Snr IT Architect in the team to towards Devops implementation, Site Reliability engineering and cloud solutions deployments.

• Architected and deployed the Jenkins and GIT and reduced the application and server maintenance time drastically.

• Architected and deployed stateless applications using the ECS, Fargate, Terraform and other AWS services. Enabled monitoring with AWS CloudWatch.

• Architected and deployed the business intelligence tool (AWS Quicksight) with the help of Terraform and other AWS services (SQS, SES, S3, Dyanamodb, Aurora, Firehose, Kinesis, Lambda etc.)

• Designed and deployed the ELK stack (Elasticsearch, Logstash, Grafana, Elastalert) for the application monitoring.

• Regularly deploying and managing the solutions based on the AWS services such as EC2, RDS, ELB, CloudWatch, CloudFormation, EKS, ECS, IAM, S3, VPC, AWS Support, ECR, SED, Certificate Manager, SNS, SQS, Lambda, System Manager etc.

• Built and provisioned 11 SaaS environments regularly with AWS and Terraform.

• Used Python, shell, Lambda and Jenkins (Groovy scripts) to automate the tasks and jobs when required.

• Scheduled an automated shutdown of AWS resources to save the cost according to the schedule using the DynamoDB and Lambda.

• Migrate the on premise the infra to AWS SaaS solutions when its required.
• Participate in the cloud partner meetings in Europe.
• Coordinate with development teams to build the pipelines to reduce the errors.
• Migrating the ELK monitoring to the Sumologic.
• Train, document and KT with other teams.

• I was member of the Devops and cloud team. My team was automating the software lifecycles of internal applications using the tools mainly GIT, Jenkins, Sonarqube, Jfrog, Ansible, Docker, AWS and Kubernetes.

Achievements under this project:

• Built the CI-CD pipeline with Jenkins, Github, SonarQube, Jfrog and Dockerhub
• Reduced the time of software life cycle with the help of the previous pipeline.
• Interacted with AWS support and migrated the applications using the containers in the EC2
• Built the Jenkins jobs that reduced the dependency over the dev team and enhanced the performance of support teams and other integration teams.
• Followed up with Dev team for building the micro services towards the containerized platforms.
• Consulted the partners for the new UI and app versions.

• This project was mainly focused on this Linux administration, cloud administration and supporting the Devops practices tools such as GIT, Jenkins, Ansible and terraform
