A distributed key-value database built on the Bitcask model, with drop-in Redis client compatibility via RESP. Nodes replicate through Raft, and it ships as a Go SDK with built-in gRPC load balancing.

A minimal Go web framework built on net/http, inspired by Bottle. Middleware chaining, route groups, and zero external dependencies, small enough to read through in an afternoon.

A distributed cron scheduler with no single point of failure. Jobs route across worker nodes via Kafka instead of a single machine. A three-tier queue handles retries, and the crontab syntax is extended for cluster targeting.

A Layer 7 load balancer with multiple routing strategies. Failing backends get routed around automatically and rejoin once they're healthy again, and config changes reload live without dropping active connections.
