TECHNICAL SKILLS: 1. Linux Fundamentals & Scripting: I was tasked to manage Linux-based servers. Knowledge of file systems, permissions, networking, and basic command-line operations . Scripting languages, such as Bash, Python was used for automating the tasks. 2. Version Control Systems Proficiency in Git and platforms like GitHub, and Bitbucket is foundational for code collaboration, branching strategies, and managing infrastructure as code. 3. CI/CD Pipeline Management Understanding and implementing Continuous Integration and Continuous Deployment using Jenkins: 4. Patching and Installation of software on multiple servers using Ansible. Other task used with Ansible : - Used to maintain desired states of systems across environments. 5. Worked on the side project in our team in the building of Docker Images, testing and deploying the images from the Dev. Environment to the Testing Environment before deployment after effective approval. Tool used: DOCKER SOFT SKILLS: 1. Collaboration & Communication (GitHub - Used to manage source code and track changes. These tools enable collaboration, branching, and pull requests in development workflows.) : I have worked closely with software developers, testers, security teams, and product managers. 2. Problem-Solving Critical thinking and the ability to troubleshoot infrastructure, deployment, or application issues . 3. Adaptability Open to continuous learning and quick to adapt to new tools and methodologies. 4. Attention to Detail: Have had to handle the Configuration of files, CI/CD scripts, and cloud infrastructure setups which could disrupt systems if not handled with care in collaboration with my team members. And made sure each step implemented was documented for further use if needed. Environment : Gits and GitHub, Jenkins, Docker, Ansible. / AWS (EC2, S3, IAM, ELB, VPC), Bash , Basic Python Knowledge.
