Humanoid robot with partial autonomy. Occasionally useful.
Founder of PVR Labs, where I build fast, lightweight, self-hosted software for developers and small teams.
- AI Badger - A local-first CLI for extracting precise, token-efficient codebase context for ChatGPT, Claude, Grok, and other AI tools. Built in Go, with no repository upload required.
- StatLite - A tiny, self-hosted monitoring dashboard for Spring Boot applications. Actuator metrics, SQLite storage, and simple charts without a full Prometheus and Grafana stack.
- Scriptella ETL - Open-source Java ETL and script execution tool built around SQL and simple configuration.
- Local-first developer tools for focused AI-assisted workflows - AI Badger, Agent Scripts
- Lightweight, self-hosted software for small servers and teams - StatLite
- Fast and efficient Java systems - Scriptella ETL
