About

Profile photo

I'm an AWS Certified Solutions Architect with expertise spanning DevOps, Platform Engineering, and Site Reliability Engineering (SRE). I design and implement cloud-native solutions that are scalable, secure, and cost-optimized.

As a Platform Engineer, I build internal developer platforms that accelerate software delivery. I create self-service infrastructure, golden paths, and tooling that empowers development teams to ship faster while maintaining security and compliance.

My SRE background drives my focus on reliability and observability. I implement SLOs, error budgets, and incident management processes. I specialize in Kubernetes, Terraform, CI/CD pipelines, and Infrastructure as Code.

I'm passionate about GitOps workflows, DevSecOps, and building systems that are observable, maintainable, and resilient by design.
