I build reliability primitives for AI coding agents.

My current focus is OpenCode: readiness checks, runtime maintenance, session review, local project memory, and multi-machine agent coordination. I spent 21 years building backend systems, data platforms, and distributed infrastructure. Now I apply that production engineering background to AI-assisted software development.

OpenCode Reliability Toolkit

Small tools that make AI coding agents more reliable in real engineering workflows.

ToolWhat it does
opencode-waitforAdds wait_for for HTTP, TCP, and command readiness checks so agents stop writing fragile sleep loops.
opencode-db-cleanSafely analyzes and vacuums bloated OpenCode SQLite databases with backups and integrity checks.
opencode-session-reflectionReviews agent sessions as engineering evidence: communication gaps, recurring failures, and reusable workflow opportunities.
opencode-plugin-memoryGives OpenCode a local, inspectable project-memory layer with selective cross-session recall.
opencode-fleetLets one master OpenCode instance coordinate multiple remote OpenCode nodes across machines.

Background

21 years in software engineering across backend infrastructure, big data, distributed systems, and AI-native applications. Earlier work included Hadoop, Spark, Flink, Hive, Kafka, and production data platforms. Recent work focuses on LLM applications, multi-agent systems, LangGraph, OpenCode, and AI-assisted engineering workflows.

OSS contributor to Byzer, Apache SeaTunnel, and Apache DolphinScheduler.
