About

I'm a DevOps and Platform Engineer who keeps complex delivery systems running smoothly, securely, and at scale. I help teams ship faster by building reliable CI/CD pipelines, automating infrastructure, and reducing the operational toil that slows engineering down. In my current role as a Systems and Security Engineer at DeepDrishti.ai, I design and maintain Jenkins and GitLab CI/CD workflows, write automation in Python, Bash, and Groovy, and support Linux-based production environments by troubleshooting deployments, services, and runtime issues. I work across AWS (EC2, EKS, VPC, IAM, S3, RDS, CloudWatch) to support secure, scalable cloud infrastructure, and use Docker, Kubernetes, kubectl, and kustomize for containerized application delivery. I bring strong observability and reliability experience using Grafana, Prometheus, Splunk, and ELK Stack, helping teams catch issues early, improve alert quality, and resolve incidents faster through root cause analysis. I also implement secure-by-design practices with Vault for secrets management, Nginx for ingress and reverse proxy configuration, and ongoing vulnerability and patch management. What sets me apart is my ability to bridge development, infrastructure, and security: I don't just keep systems running, I make them safer, more automated, and easier for developers to work with. I'm a TryHackMe Top 1% ranked security practitioner, and I write technical articles on Medium covering DevOps, cloud security, and infrastructure topics. I'm actively growing toward Cloud Security, DevSecOps, and Platform Engineering roles, and I'm always open to connecting with teams solving interesting problems in reliability, automation, and secure infrastructure.
