The most amazing...
...infrastructure I have built was a Kubernetes cluster, with its Helm charts and configuration scripts and CI/CD implementation using Jenkins.
Employment
Experience
- Built a Kubernetes Cluster with CI/CD in DMZ Environment
Designed and built scalable infrastructure using Cloud-Native architecture for a large scale distributed application which is deployed on hybrid cloud systems (Private Cloud + AWS) using Kubernetes and Docker, created CI/CD pipelines with Jenkins to spin up the whole infrastructure over CloudFormation and manage deployments using CloudFormation, Ansible, and Helm.
- Established Connectivity with AWS Direct Connect
Physically connected the client’s data centers to AWS infrastructure using AWS Direct Connect and troubleshoot issues which include OSI layers 1-4, from setting up the physical connection, establishing ARP using 802.1Q VLAN encapsulation, and establishing eBGP peering relationships with AWS infrastructure.
- Built Microservices Architecture for .NET Apps Using Azure Kubernete Service (AKS)
Built an architecture for .Net Microservices for a large eCommerce platform using Azure Kubernetes Services (AKS), the project consists of an API Gateway and 5 or more (dynamic) microservices developed on .Net Core, I had to containerize the application according to the AKS ecosystem and then I designed the CI/CD pipelines using Azure DevOps to orchestrate the build and deploy process – I also consider the addition of new microservices using the Pipeline so developers can add a new service behind the API Gateway by themselves using a Pipeline in Azure DevOps.
For DevSecOps, I used VeraCode and SourceClear to scan all locally developed and third-party code, so all builds are scanned before getting to the build pipeline and there JFrog Xray was used to scan the docker containers. - Migrating from Heroku to AWS ECS
The client was using a complex application running a blend of interdependent services with different tech stack. The monthly cost was huge for the convenience of Heroku so we decided to move the application to AWS ECS Cluster with AWS Fargate, though the CI/CD part was challenging, but we managed to implement a blue/green deployment model using AWS Code Star.
