## 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
