Summary of Work Experience:At the outset of my career, I gained significant expertise in cloud computing with a focus on AWS. This involved creating CentOS 7 servers, meticulously configuring software, and installing libraries, primarily within Docker containers. I leveraged Terraform for infrastructure provisioning, ensuring seamless development workflows. Additionally, I implemented data lifecycle management policies using AWS S3 to efficiently store and manage data.I adeptly utilized AWS Autoscaling groups and load balancers to guarantee optimal server performance, even under high traffic loads, contributing to the stability of the entire system.In the realm of data visualization, I orchestrated Elasticsearch and Kibana instances running within Docker containers on CentOS 7 servers. Employing Docker Compose, I orchestrated the deployment, ensuring the components worked seamlessly together. My responsibilities extended to integrating various APIs and orchestrating the data flow into Elasticsearch indices. I subsequently designed and constructed diverse data visualizations, skillfully curating dashboards for insightful data presentation.Security was a paramount concern, and I addressed it by configuring NGINX reverse proxy for passwordless authentication. Furthermore, I implemented SSL certificates and linked domain names to bolster system security.In parallel, I implemented robust Continuous Integration/Continuous Deployment (CI/CD) pipelines for Node.js applications using GitHub Actions. This streamlined the development process, facilitating automatic deployments to the production server. Any changes made to the source code were efficiently deployed to the production environment upon committing, enhancing the agility and efficiency of the development workflow.My work has consistently revolved around enhancing operational efficiency, ensuring security, and promoting seamless development and deployment practices.
