The most amazing...
...artifact I've built is a process for creating custom AMI, provisioning ASG, deploying the code, and refreshing it with new EC2 when the golden AMI is released.
Work Experience
Principal Consultant
Indian MNC
- Architected solutions based on the hybrid cloud architecture between AWS public cloud and client on-premise systems. Assessed, designed, executed, and consulted on cloud migration and application modernization.
- Wrote the HLD for the overall migration to AWS, collaborating with the client's cloud architects on the proposed network architecture, high availability, disaster recovery solution, Amazon EKS provisioning, and ASG creation.
- Created custom AMI by automating the manual steps followed to configure the VMs for on-premises, including server provisioning and code deployment.
- Refractured the back-end microservice codebase to make it EKS-ready. Understanding the VM configuration and capacity with the help of AWS Application Discovery Service and AWS Migration Hub, I exposed the workload (EC2 and EKS) using ALB and NLB.
- Architected various solutions for security and compliance, like firewall rules using NACL and security groups and creating routable and non-routable private and public subnets under VPC, WAF for ALB, and network policy inside Amazon EKS.
- Created POCs for migration-related requirements like Amazon MSK Serverless and NGINX Ingress solutions. I also worked on monitoring solutions.
- Created an AWS FIS stress test using Chaos Mesh for the pods deployed in Amazon EKS.
Technology Architect
Cognizant
- Assessed, designed, and executed application modernization and infrastructure transformation using the cloud.
- Architected solutions based on the hybrid cloud architecture between AWS public cloud, AWS Outposts, and client on-premise systems.
- Provisioned the resources like Amazon EC2, RDS, PostgreSQL, Lambda, NACL, security groups, etc.
- Designed and implemented message transformation into HTTP, SOAP-based messages using the WIFE parser. Deployed the solution as a Spring Boot application inside Amazon EKS.
- Refactored the Mule components into microservices, deployed those as Spring Boot applications inside AWS EKS, and exposed those using Kong Ingress Controller.
- Derived various integration data models based on BIAN and IBM Information FrameWork (IFW).
Associate Information Technology Consultant
Tata Consultancy Services
- Integrated cloud-based systems like SFDC and legacy mainframe applications developed in Unisure and HPS via WebSphere MQ and WebSphere Message Broker.
- Implemented SOA as part of the client's digital initiative with integrations between Adobe CQ5, Salesforce, and third-party vendor applications like CBIS and ARC using WebSphere MQ and WebSphere Message Broker.
- Troubleshot integration-related issues like certificate exchange and firewall network trafficking with different third parties. Implemented services and exposed them in the ESB layer.
- Maintained the existing application code, conducting deployments in production and nonproduction servers.
- Coordinated the release deployments with the process owner for issue resolution, fixed defects, and performed unit testing.
Senior Developer
Veloz Software Solutions
- Analyzed and implemented the requirements within the project after getting them from the onsite coordinator.
- Wrote adaptors to fetch data from queues, topics, and subscribers of JCAPS.
- Performed dashboard feature enhancements after studying the JCAPS internal processes.
Module Lead
Tathya
- Learned the entire process and preparation of the module.
- Created reports for different custom requirements.
- Customized existing modules to match different subsidiary requirements.
Experience
eCommerce Workload Migration into AWS
• Automated the entire server creation process in AWS, including custom AMI creation with Hashicorp Packer and PowerShell, ASG creation, workload exposition using Terraform, etc.
• Deployed the codebase into the ASG using Jenkins and AWSCodeDeploy deployment agent.
• Refreshed the ASG EC2 instances as and when the client released a new custom AMI.
• Created AWS EKS and its various components (like CNI, Fluent Bit, the Dynatrace Operator, Calico, etc.) using Terraform and Helm.
• Installed the NGINX Ingress Controller.
• Exposed the Kubernetes services via ALB outside the AWS EKS so that the front-end application and other business partners can consume the services.
• Reconfigured the existing Jenkins pipelines to AWS EKS for code deployment.
MT101 STP Solution
• Created the Spring Boot-based microservice service and deployed it in AWS EKS.
• Created the AWS EKS in AWS Outposts infrastructure.
• Created a VPC interface and gateway endpoints to connect to the various components from AWS EKS.
Kong Installation and POC
Monitoring Solution Installation for Apache Kafka
• Installed AWS-managed Prometheus and managed Grafana.
• Configured Amazon Managed Grafana for federated user access and dashboard creation.
• Created Terraform scripts and deployed them using a Jenkins pipeline for the production and non-production environments.
Custom Developer Portal for APIs
Hosted a Dining-related Web Application in AWS
• Created ECS Fargate clusters using CloudFormation and Azure DevOps pipelines.
• Deployed the codebase into ECS clusters using the Azure DevOps pipeline.
• Configured Dynatrace OneAgent to send the metrics to Dynatrace Managed clusters installed into a different VPC and a different account.
• Configured Splunk to send the application logs deployed in ECS.
• Configured Elasticsearch to share the logs and metrics to Elastic using Filebeat and Metricbeat.
