PROFILE
Vlad Krinitsyn
Worked on the celestiaorg/celestia-app repository to deliver cross-cutting improvements in observability, performance, and cloud deployment. Enhanced the monitoring stack by integrating Pyroscope for continuous profiling, adding OpenTelemetry instrumentation, and developing Grafana dashboards with label sanitization for granular filtering. Improved fibre network throughput and data-plane efficiency by introducing asynchronous transaction confirmations and optimizing storage with direct Pebble API usage. Upgraded cloud readiness through Ubuntu 24.04 support, AWS EC2 provider integration, and presigned S3 payload URLs. Addressed deployment reliability by refining tarball packaging and stabilizing CI tests. Utilized Go, Docker, and AWS SDK to streamline backend and DevOps workflows.

Apr 1, 2026Month: 2026-04 – Delivered cross-cutting improvements across observability, performance, and cloud readiness. Key features include an enhanced observability stack (Pyroscope integration, OpenTelemetry instrumentation, Grafana dashboards) with label sanitization; major fibre network and data-plane throughput improvements; expanded profiling visibility with Go runtime metrics; store/encoding optimizations via direct Pebble API and value separation; and cloud/platform readiness (Ubuntu 24.04 upgrade, AWS EC2 provider, presigned payload URLs) along with reliability fixes for tarball deployments and CI tests. These efforts reduce latency, improve troubleshooting, accelerate data uploads, and simplify multi-provider deployments, delivering business value in reliability, performance, and operational insight.
