Hi, I’m Jack!
I’m a software engineer at Veterans United. Since joining in 2022, I’ve worked on tools that help people navigate the home loan process, including a conversational prequalification assistant.
I like working through tricky problems with other people, helping teammates, and building things of my own. Here are a few of those.
Things I’ve built
Execution-path evaluation for tool-using agents. Checks tool selection, arguments, and execution order to help identify failures and unnecessary steps.
Source verification for generated answers. Breaks each answer into individual claims, checks them against retrieved evidence, and flags unsupported statements.
A reinforcement learning agent that learns to play Atari games from raw screen pixels and score feedback, without being given the rules. Plenty of trial and error along the way!
Away from the keyboard
Outside of work, I like making and listening to music, reading, playing basketball, and getting out for a hike.
