PROFILE
Mikhail
Over three months, To Myrrc developed and enhanced core backend features for the neondatabase/neon and neondatabase/autoscaling repositories, focusing on observability, reliability, and API quality. They delivered a PostgreSQL max_connections monitoring metric using Libsonnet and SQL, enabling improved capacity planning. For autoscaling, they implemented Prometheus-based VM network traffic metrics with iptables integration, increasing the accuracy of external network observability. In July, To introduced lifecycle and failover improvements to the Local File Cache, reinforced replica promotion logic, and automated OpenAPI linting for API consistency. Their work leveraged Go, Rust, and Kubernetes, demonstrating depth in distributed systems, monitoring, and API development.
