About

I don’t just “work in DevOps.” I solve the gap between development and operations by building systems that are fast, reliable, and scalable. With 3 years of experience, I specialize in automating infrastructure and CI/CD pipelines so teams can ship faster without breaking production. 🚀 What I bring: • Build and optimize CI/CD pipelines (Jenkins, Azure DevOps) • Design scalable cloud infrastructure on AWS Infrastructure as Code using Terraform Containerization & orchestration using Docker & Kubernetes • Improving system reliability and reducing deployment failures 📉 Impact I focus on: • Faster deployments • Fewer production issues • Scalable and cost-efficient systems 🛠 Tech Stack: AWS | Terraform | Kubernetes | Docker | Jenkins | Azure DevOps | Python 🔥 Currently Exploring: AI + DevOps (log analysis, intelligent monitoring) Building smarter, self-healing systems If you're looking for someone who can automate, optimize, and scale your infrastructure, let’s connect > rohanbhowmik001@gmail.com
