I have around 12 years of experience in software development, and in my past work experiences, I have participated in the development of financial technology, real-time trading platforms, accounting systems, and gaming platforms.I was using C# and ASP.NET Core, and I have experience in Linux, Docker containerization, and Kubernetes (K8S). I use tools like Dockerfile, GitLab CI, Azure DevOps, Jenkinsfile, or Ansible Playbooks along with shell scripts or python scripts to deploy containerized applications to AWS EKS or GKE clusters. I am skilled in developing distributed backend API services and using service events to reduce dependencies among various API or worker services.Due to business requirements, I have also integrated with API services from different vendors, such as using sockets to interface with AS400 systems or US stock brokers for real-time trading services.For testing purposes in some system integrations, I have written fake services using Node.js Express or Python FastAPI to build test data and provide testing services for system integration testing.I have experience using cloud services as follows: I am most familiar with AWS and have complete experience in packaging applications and automating deployment to AWS EKS. I have also used GCP and Alibaba Cloud to a limited extent. To gain practical experience in CI/CD and cloud environment deployment, I have set up a Linode LKE (K8S) cluster on my private Linode server and automated deployment of my ASP.NET Core application to Linode K8S through GitLab CI. I also created an Nginx ingress reverse proxy on Linode and deployed MySQL, Elasticsearch, Redis, and RabbitMQ services to Linode K8S pods. I also established a jumper server, firewall, and ELK log and monitoring mechanisms for API services in this private Linode environment.I am currently maintaining an open-minded attitude and actively seeking my next opportunity in software development.My primary focus for job opportunities is in C# and ASP.NET Core backend development, but I am also very interested in exploring opportunities to develop backend services using Python or Node.js.If my experience is of interest to you, please feel free to contact me at any time.
