I build resilient platforms for millions of users on cloud, on-prem, kubernetes.

Message

At Inkitt, I own reliability and infrastructure for a publishing platform spanning four Kubernetes clusters, 1,000+ VMs, and 120+ databases across GCP and Hetzner. I migrated a 150 TB ClickHouse cluster with zero downtime and data loss, reduced infrastructure costs by about $50k annually, and helped maintain 99.9% uptime.

Previously at Coffee Meets Bagel, I supported a global dating platform serving 10M+ users, rebuilt AWS infrastructure after a security incident within one week, and introduced GitOps, observability, and structured incident-response practices. I also built Django and FastAPI services and led the move from VM-based services to Kubernetes.

I bring 9+ years of experience building large-scale platforms, from a 3,000+ VM PaaS at Ringier Axel Springer Polska to LLM-driven operational automation. I focus on practical reliability through SLI/SLOs, infrastructure as code, strong observability, and resilient incident response.
