Hello World, You are seeing a DevOps Engineer profile. I graduated from the University of Information Technology (Vietnam National University HCMC). I have a good base knowledge of Networking and Telecommunications. DevOps is my passion so I decided to change my career path from DotNet Software Engineer to DevOps Engineer. Currently, I'm working on a project related to mobile testing. I'm responsible for building, managing and scaling CI/CD system. In my project, I have done such things: - Implement CI (Continuous Integration) system using Jenkins especially Jenkins Pipeline. - Replace Jenkins with Travis CI because Jenkins becomes unstable and needs to self- managed nodes. - Setup, configure and manage IT infrastructure automatically by Ansible. - Implement CD (Continuous Deployment) system using Rundeck. - Work with AWS (Route 53, EC2, S3, RDS, ECS, EKS) for building the entire application ecosystem. - Work with Elastic Stack (Elasticsearch, Logstash, Kibana) for application log management. - Write custom rules for alerting critical messages within five minutes or normal messages within twelve hours from Elasticsearch. - Setup and configure Elastic APM to monitor application performance. - Work with Docker (dockerize applications, build applications from docker images). - Build API documentation by using Swagger and user documentation by using Slate. - Setup and configure reverse proxy Nginx to handle requests for ensuring the availability, scalability, confidentiality. - Work with mono-repo to centralize repositories and manage dependencies easily. - Setup and configure Metabase to analyze the company’s data. - Code scripting languages such as Bash, Python. I know that I'm just a drop in the bucket but I will do the best things to make everything gets better and stronger.
