ORLANDO, FL // SENIOR SOFTWARE ENGINEER
Connor
Hallman
I build enterpise-grade systems end-to-end, from database to deployment, across whatever domain the problem lives in. I have six years of production engineering experience across data pipelines, SaaS products, internal tools, and open source.
At Vintory I replaced a failed $300K offshore effort solo in a month, normalized 100M+ owner records with custom identity resolution, and now run the platform as both lead engineer and de-facto product manager.
Vintory
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, and now run the development team as both lead engineer and de-facto product manager.

BifrostMCP
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.

Optimizing Levenshstein for Fuzzy Name Matching
Myers bit-parallel gave a 10x speedup over naive Levenshtein. Here's how a handful of cheap pruning tricks pushed it another 5x.
How Postgres CTIDs Gave Me a 30x Speedup on Processing 200 Million Rows
Indexes don't solve everything at scale. A story of how I cut 3-days worth of execution time down to a few hours by exploiting PostgreSQL's physical row addresses for cache-friendly sequential reads.
