About Me

I'm Jacobus — an engineering leader transitioning from senior product engineer into coaching and leadership. I work with engineers 1-on-1, improve team processes, and still build tools and systems hands-on — from AI-powered knowledge graphs to autonomous build workflows.

I'm a follower of Jesus, a father, a husband, and a creative maker who builds indie games and software for the joy of it.

What Drives Me

My work is grounded in a conviction that building well is an act of stewardship. I follow Jesus, and that shapes how I approach craft, people, and purpose.
