Hi! I’m a Cloud & DevOps Engineer with a mix of hands-on experience from India and Germany. I’ve spent the last few years working with AWS, Linux, Docker, Terraform, and CI/CD tools to help teams deploy faster, run more reliably, and keep their infrastructure simple and clean. I like breaking down problems and fixing things quickly. Whether it’s a small script, a Dockerfile issue, a server that doesn’t start, or a full AWS setup, I aim to make everything easy to understand and smooth to use. Here’s where I can help you right away: • Set up and manage AWS services (EC2, S3, IAM, CloudWatch, RDS, VPC) • Write clean Terraform modules and automate infrastructure • Build or fix CI/CD pipelines using GitHub Actions or Jenkins • Containerize apps with Docker and troubleshoot deployment issues • Improve security, monitoring, alerts, and cost control • Handle Linux server tasks, permissions, networking, cron jobs • Take on small quick fixes if you need fast, affordable help Recent project: I built and deployed a full lead-generation web app (Renevatec) on AWS using EC2, S3, Docker, Terraform, and GitHub Actions. The setup cut deployment time, made rollouts consistent, and reduced manual work. I’m easy to work with, clear in my communication, and always aim for practical, reliable solutions.
