Connor
Hallman

Three years as the primary engineer behind Vintory's data and tooling platform. Built the normalization and identity resolution system for 30M addresses and 100M owner records, replaced a failed $300K offshore effort solo in a month, and now run the platform as both lead engineer and de-facto product manager.

A VS Code extension that acts as an MCP server, exposing language server features like go-to-definition, find-all-references, and call hierarchies directly to AI tools. Instead of guessing where a function is defined, an AI can ask VS Code and get the exact answer.

Takes a Postman collection JSON and generates a complete, organized C# project with interfaces, concrete client implementations, all request/response types, and zero external dependencies. Everything runs in the browser — no user data leaves their machine.

Northrop Grumman senior design project: an agentic drone that accepts natural language commands and executes them autonomously. A locally-hosted LLM parses commands into ROS2 action sequences, RTAB-Map handles real-time SLAM, and a React dashboard provides human-in-the-loop control.

A full internal calling platform handling everything from lead import to campaign execution to post-call AI analysis. VAPI handles the actual calls; the system cycles through numbers, handles faults gracefully, and auto-terminates on configured stop conditions.

Built because every existing tool was too simplified to trust with real money. Runs a year-by-year simulation where amortization, appreciation, tax write-offs, capital improvements, and recurring expenses all interact correctly. The calculation engine is open source.
