Project History
Offensive and Defensive Security Attack Application on RKE
A security integration application that was built on Angular. It runs in Docker with PostgreSQL as a data store and is connected to several offensive and defensive tools with an API.
I was the one-person shop for DevOps-related issues and needs. My main tasks were:
• Creating Dockerfiles.
• Developing a stable development environment for the team that runs on AWS with Terraform and Terragrunt running on RKE.
• Building all the necessary infrastructure elements, including Istio, Grafana, Prometheus, Loki, PGO, Keycloak, MinIO, Sentry, and Grafana Tempo.
• Providing Helm with Helmfile for fast stack deployment.

Web Application Environment for Residential Services
A Node.js-based application consisting of API services and three clients, including admin, back-end, and client interfaces. I was tasked with deploying the application on AWS. I utilized Amazon ECS services to manage Docker-based applications, incorporating GitHub Action workflows that include switches for deploying to various environments such as development, QA, and production. These deployments can be controlled using a permission matrix. Also, I supported them with content delivery network services on Amazon S3 and HA, including Amazon RDS for PostgreSQL as a data source.
Transforming Mobile Core Applications to Microservices
https://www.pentenetworks.com/Multiple Node.js and Java-based applications that provide a mobile core service. My responsibilities included:
• Creating cloud-based Kubernetes services, including Amazon EKS and Azure Kubernetes Service (AKS).
• Developing microservices using Docker for all applications and pipelines for development and deployment processes.
• Deploying and administrating infrastructure that included a database and system bus in Apache ZooKeeper and Kafka.
• Creating cloud-based Kubernetes services, including Amazon EKS and Azure Kubernetes Service (AKS).
• Developing microservices using Docker for all applications and pipelines for development and deployment processes.
