What I'm looking for

I'm looking for infrastructure or platform work where I can own production systems end to end, solve difficult reliability problems, build practical automation and LLM tooling, and work remotely or relocate.

At SMART, I own production infrastructure for an enterprise platform serving customers in education, manufacturing, and transportation. I operate 12 Kubernetes clusters across 45 nodes handling roughly 10K RPS at 99.85% uptime.

I've progressed from DevOps intern to Infrastructure / ML Platform Engineer, building GitOps delivery, backups, disaster recovery, on-call operations, and bare-metal deployments in customer data centers. I’ve migrated microservices from VMware to k3s, automated ArgoCD-based releases, and reduced issue resolution from months to about one week through an internal field operations platform.

I investigate production failures deeply, from authentication bypasses and silent content outages to provider-side network filtering and PostgreSQL backup failures. I turn incidents into durable fixes, alerting, runbooks, and safer operating practices.

I also built an internal LLM-powered infrastructure analytics platform across all clusters, using Kubernetes events, Prometheus metrics, Qdrant, embeddings, reranking, model fallback routing, MCP servers, and agentic workflows. Outside work, I build and publish open-source Linux and terminal tools, including SSHub, a Rust terminal UI for SSH.
