About

I'm a software engineer with a B.S. in Computer Science from Southern Methodist University.

I have 3+ years of experience building integrations at DocJuris, SQL and Python analytics used by the C-suite at Caliber Collision, and full-stack web apps like Pokeboard.net.

I'm based in Houston and looking for on-site or hybrid software roles.

Self-hosted

Self-hosted AI assistant on a home server cluster. RAG memory with hybrid keyword + vector search (SQLite FTS5, sqlite-vec, nomic-embed) exposed via an MCP server; agent router with approval-gated tool calls; eval harness that raised routing accuracy from 42% to 95%+.

Piper architecture A user request goes to an agent router, then an approval gate, then tools. The tools call an MCP server, which runs hybrid keyword and vector search over a SQLite memory store. An eval harness tests the router and raised routing accuracy from 42% to over 95%.
