I build AI systems and data platforms. 25 years across GIS, software engineering, cloud infrastructure, and applied AI — now shipping Dhi and LLM Governance Engine.
AI-powered fill-in-the-middle autocomplete for VS Code
PII firewall and YAML policy engine that stops sensitive data before it reaches any LLM
How to build a VS Code chat panel with server-sent event streaming, prioritized context-slot assembly, hybrid RAG retrieval, and a three-process webview architecture — no API keys, all open-source models.
How I added RAGAS-based faithfulness and context-utilization scoring to an open-source LLM governance engine — plus a post-response governance rule that catches hallucinations after the model has already started streaming.
How I built an open-source PII firewall and governance policy engine for LLMs in a weekend — blocks sensitive data before it reaches GPT-4o, with YAML rules, audit trail, and webhook alerts.
How to add full repository intelligence to an AI IDE: multi-language Tree-sitter chunking (Go, Rust, Java, JavaScript), BM25 hybrid search with RRF, .gitignore-aware file discovery, and new /index-dir and /search API endpoints.
Deep technical posts — building in public, shipping open source, and lessons from production AI systems.
