I build self-service cloud platforms that make infrastructure delivery, reliability, and operations easier for developers.

What I'm looking for

I'm looking to build and operate cloud platforms as products, with ownership across infrastructure, developer self-service, security, observability, CI/CD, and reliable production operations.

At Exodus, I own internal platform tools end to end, from Node.js and Go development through AWS infrastructure, CI/CD, security, observability, and production support. I helped shift infrastructure delivery to developer self-service through shared Terraform modules and reviewed pull requests.

I build and operate AWS and Kubernetes platforms across EKS clusters, using Terraform, Terragrunt, Atlantis, Helm, Argo CD, Docker, and GitHub Actions. I designed an intelligent RPC proxy that sustained roughly 10K requests per second at peak with automatic failover and no gateway timeouts or user-facing failures.

I maintain monitoring for more than 200 production blockchain nodes and built an automated version-management system for 42 networks, replacing manual release tracking with automated checks, tickets, hard-fork detection, and incident alerts. I also author reusable Claude Code and Codex agent skills that let developers safely handle operational tasks themselves.

Earlier, I built reusable AWS infrastructure modules, GitOps delivery workflows, cost-optimization automation that reduced AWS spend by about 60%, and monitoring and self-healing systems. I’ve mentored DevOps engineers and enjoy improving developer experience through secure, reusable platform capabilities.
