👨‍💼 About Me – Rajasimman S

Lead SRE | DevOps Architect | Cloud Native Practitioner | Platform Engineering Enthusiast | AI in DevOps Explorer

🚀 Who I Am

I'm a pragmatic and outcome-driven Cloud & DevOps Architect with over a decade of experience in building scalable, observable, and cost-efficient cloud-native platforms across AWS, GCP, and Azure. My career spans DevOps, SRE, Cloud Operations, and Platform Engineering, with a deep passion for automation, open source, and continuous learning.

Recently, I’ve been diving deep into the intersection of AI and DevOps, exploring how Generative AI and LLMs can improve engineering workflows, platform intelligence, and developer experience. My AI toolkit spans across OpenAI, Claude, Gemini, Llama 3, Ollama, AWS Bedrock, and Azure AI Foundry, which I’ve used in real-world Cloud and DevOps contexts for observability, automation, and incident response.

I've architected and delivered mission-critical infrastructure for large-scale platforms including DIKSHA, IGOT Karmayogi Bharat, and others, helping teams adopt GitOps, Kubernetes, IaC, and SRE best practices. I’ve also led successful cloud migrations, cost optimization, and DevSecOps transformations, impacting platform performance, reliability, and security.

🧩 Core Philosophy

"Design systems that don’t need babysitting."

I believe in building resilient, self-healing systems backed by automation-first thinking. Whether it’s infrastructure, CI/CD pipelines, observability, or incident response, my approach is to eliminate toil, create repeatable patterns, and empower development teams through platforms that just work.

🎯 My Strengths

✅ Cloud Strategy & Architecture – Multi-cloud experience in AWS, GCP, Azure. Infra design focused on HA, DR, cost-efficiency.
✅ SRE & Observability – Driven SLAs/SLOs, error budgets, Prometheus, Grafana, Alerting, Blackbox testing.
✅ Platform Engineering – Self-service tools using ArgoCD, Helm, GitHub Actions, internal developer portals.
✅ CI/CD Pipelines – Built secure, scalable GitHub Actions pipelines for Docker/K8s/Helm apps.
✅ AI in DevOps – Leveraging LLMs like OpenAI, Claude, Gemini, and Bedrock for intelligent automation, RCA analysis, and platform observability.
✅ Cost Optimization – Helped reduce ₹30L/month cloud spend using smart architecture and tooling.
✅ Security & Compliance – DevSecOps, secrets management, policy-as-code, container scanning.
✅ Leadership & Mentorship – Led teams across DevOps/SRE functions. Known for being hands-on, mentoring juniors, and elevating team maturity.
