Summary
🤩
Rockstar🎓
Top SchoolPaulin Todev is a Senior Software Engineer based in London with 11 years of experience building reliable back-end systems and observability tooling. Currently at Grafana Labs, he focuses on tracing and OpenTelemetry integrations, bringing pragmatic fixes that prevent panics and improve collector interoperability. Previously he spent seven years as a C++ developer at Barclays Investment Bank, honing performance-sensitive and production-grade engineering skills. Paulin is an active open-source contributor to prominent projects like Prometheus and the OpenTelemetry Collector, where his work on scrape loops, discovery, and receiver/extension robustness improves monitoring fidelity at scale. He combines a theoretical physics background from the University of Glasgow with practical DevOps experience, which surfaces in careful attention to metrics, caches, and edge-case behavior. Colleagues value him for tackling low-level stability issues that quietly make large distributed systems more dependable.
