+- **Infinity Interactive** (2013–2026) — More than ten years, starting as a developer and growing into VP of Technology. Shaped technical strategy across dozens of client engagements, built and led a talented team, and learned more about myself as both an engineer and a leader than I thought I had left to learn.
