About

Professional summary

I am a Platform Engineer with over three years of experience building internal developer platforms, Kubernetes infrastructure, and cloud-native tooling on AWS.

I specialize in enabling self-service infrastructure provisioning through Crossplane, Backstage, Kubernetes operators, Infrastructure as Code, and GitOps workflows. My work focuses on reducing developer friction while improving platform reliability and scalability.

I have designed and maintained CI/CD systems using Jenkins, Argo CD, Flux, Docker, and Amazon EKS. I also have hands-on experience provisioning cloud infrastructure with Terraform and managing server configuration through Ansible.

I work extensively with observability platforms, including Grafana, Loki, Tempo, Cortex, and OpenSearch. I have operated logging and monitoring systems supporting hundreds of Kubernetes and ECS services at scale.

My primary programming language is Golang, which I use for platform automation, Kubernetes operators, CLI tools, and distributed systems projects. I also work with Python, C++, SQL, Bash, React.js, Node.js, and FastAPI.

I am passionate about distributed systems, Linux internals, container runtimes, and creating reliable developer experiences through scalable platform engineering practices.

Career history

Platform Engineer Plivo

Designed and implemented Infrastructure as Code using Crossplane Composite Resources and Compositions, enabling self-service AWS infrastructure provisioning for more than 10 internal services. Reduced provisioning time from hours to under 10 minutes.

Contributed controller-level enhancements to the open-source Crossplane AWS provider and developed Backstage plugins plus a companion CLI for self-service infrastructure, ECS service, and CI/CD pipeline provisioning. Operated the OpenSearch logging platform for more than 100 Kubernetes services and 300 ECS services, including cluster upgrades and Lambda-based ingestion pipelines processing millions of daily log events. Maintained in-house Kubernetes operators and the Backstage-based internal developer platform.

DevOps Engineer Brane Enterprises

Architected and maintained CI/CD pipelines using Git, Jenkins, Docker, Argo CD, and Flux to deploy applications reliably to Amazon EKS. Built multi-architecture Docker images for AMD64 and ARM64 workloads, enabling migration to ARM-based nodes and reducing Kubernetes cluster costs by 40%.

Maintained an observability stack based on Grafana, Loki, Tempo, and Cortex, implementing monitoring and alerting for Amazon EKS and EC2 workloads. Provisioned AWS infrastructure with Terraform, enforced server configuration through Ansible playbooks, and supported migration of development workloads from AWS to Nutanix, delivering approximately 50% cost savings.
