Work history

Staff Infrastructure Engineer | Glia

Tallinn, Estonia | July 2024 — Present

Cost Engineering & Observability Architecture: Collaborated with product and platform teams to architect a next-generation logging platform by migrating from Elasticsearch to Quickwit (Rust-based search). Designed an async ingestion pipeline via AWS Lambda, achieving a fully stateless runtime on EKS and 100% write durability during traffic spikes. Reduced annual infrastructure costs by 60% while scaling the system to petabyte-level retention.
Kubernetes Networking (Telecom/VoIP): Led the design and implementation of a Kubernetes-native networking solution for SIP signaling and WebRTC media workloads.
- Partnered with platform and telecom teams to implement a custom Multus CNI integration, provisioning direct public identities for pods and achieving zero port translation (NAT-less) connectivity for Kamailio nodes.
- Standardized the implementation to maintain Developer Experience, allowing teams to deploy complex telecom stacks using standard K8s primitives without managing low-level networking.
VPN Cost Optimization: Designed a Site-to-Site VPN solution using vSRX and BGP with AWS Transit Gateway for high availability, replacing AWS Managed VPN and reducing costs from $10k+/month to $1k/month.
Capacity Planning & Cross-functional Collaboration: Led load-testing initiatives to benchmark system limits, optimizing database subsystems to enable 3x growth in enterprise customer onboarding. Worked closely with Customer Success to resolve production audio issues, demonstrating effective cross-functional problem-solving.
