I build production AI systems on the Claude API — RAG, LLM agents, a published MCP server, and an Apache-2.0 agent-identity layer — plus polished developer tools that actually feel good to use. By day I work in AR/XR sales and support at Meta. Outside of that I’m a game developer, creative technologist, writer, and relentless tinkerer.
I care about the gap between software that works and software that feels right — clean architecture, thoughtful UX, and the kind of engineering notes that explain why, not just what. Lately I write about keeping that same care when AI lets you build ten times faster, over at rnvizion.dev.
Building on top of large language models: grounded, guardrailed, and deterministic where it counts.
| Project | Description |
|---|---|
| AIII — AI Identification Initiative | Apache-2.0 reference implementation (rnv-mcp-identity) for AI agent identity — an L1–L3 identity-and-authorization layer for MCP servers; resolves or refuses, never guesses. 46 tests, property-based eval gates, runnable FastMCP demo. Sigstore-signed releases, CycloneDX SBOM, OpenSSF Baseline at 20 of 21 controls |
| Ask the Corpus | Retrieval-augmented (RAG) assistant over my published writing — sentence-transformers + ChromaDB, grounded through Claude with citations, rate-limited and cost-guarded. Refusal is enforced, not hoped for: a CI eval suite fails the build if retrieval slips, if it stops refusing what it can’t answer, or if it starts refusing what it can. Live on Hugging Face |
| RNV Publishing Agent | FastMCP server with a Claude agent loop that automates a content-publishing workflow — validates a post’s metadata, generates its card and OG image, commits and pushes, then updates the corpus behind Ask the Corpus. Refuses to publish anything that fails validation |
| rnv-color-mcp | Color-computation server on the Model Context Protocol, published to the official MCP registry and listed in awesome-mcp-servers. Ten deterministic tools (conversion, harmony, mixing, WCAG contrast, CIEDE2000); the model decides intent, the tool owns the exact value — resolves or refuses, never guesses. Also an OAuth 2.1 resource server: RFC 9728 protected-resource metadata, enforced per-tool scopes |
A suite of five professional desktop applications built with PyQt6. Each ships with full CLI support, cross-platform CI, and three theme modes (Dark / Light / Image).
| App | Description |
|---|---|
| RNV Text Transformer | 11 transformation modes, 9+ file formats, regex builder, folder watching, compare view — backed by 786 tests and ~76% coverage |
| RNV Color Palette Manager | Professional palette management with 16+ export formats, 7 mixing algorithms, and WCAG accessibility tools |
| RNV Color Picker | Screen color extraction with magnifier, WCAG contrast checker, and color harmony generation |
| RNV Icon Builder | Multi-resolution ICO creation from PNG/SVG/ICO sources with Android, iOS, and favicon export targets |
| RNV Color Mixer | Real-world paint mixing simulation in a digital palette, powered by Kubelka-Munk theory |
