Software Engineer

I build interactive software and the systems behind it. Most recently at Asset Guardian, where I built their training software and led the US project team.

Interactive training software

Asset Guardian makes version control software for industrial automation. I turned their written manuals into step-by-step lessons for plant operators. Each one walks through the program and shows exactly where to click. Lessons run on a practice copy built from screenshots, so trainees can't change live data.

In 2025 I led the US project team, which meant cloud setup, security, and planning the work.

Doors

A first-person puzzle game I built on my own, from design doc to release. You spawn clones that copy your movements and use them to get through 50 rooms. It launched on Steam and itch.io.

Tiger's Tale

A location-based AR app about RIT's history in downtown Rochester. I joined partway through on a stack I hadn't used. I built the map system that unlocks a story when you reach a historic site.

About

I like building things people use every day and then watching them use it. That's usually where I find out what needs fixing.
