Staff Backend Engineer building scalable, data-intensive platforms. 10+ years turning complex customer problems into reliable distributed systems.
Problem: Validators faced potential slashing penalties because their existing monitoring tools had 2+ minute data latency, leaving them blind to critical events.
Solution: I built a custom monitoring stack reducing P99 latency from 2 min to 5 sec, protecting validators from financial loss.
Tech: Go, Prometheus, Grafana, Docker
Metabase MCP Server β 23
Problem: Data teams needed AI-powered analytics without complex custom integrations.
