Experience

Node.js on AWS with CI/CD

I was involved in developing a Node.js three-tier application sample that was deployed on the Amazon EKS service, utilizing a Relational Database Service (RDS) back-end.

All updates were seamlessly pushed through Jenkins pipelines.

Containerized App on K8s

Microservices application using Kafka cluster for messaging. The application runs on OKE (a managed Kubernetes service in the cloud) and uses Istio as a service mesh.

CI/CD is performed with Spinnaker. My role in the project was to design the architecture and integrate the application with the OCI cloud environment (configure native cloud Load Balancer service as K8s ingress service and design application persistence on cloud storage).

REST API with Python and Flask

https://github.com/radudobrinescu/flask-aws-devops
I was involved in developing a Python application that exposed REST APIs. The application was successfully deployed on AWS, and the entire infrastructure on AWS was automatically provisioned using Ansible.
