Leonard Guelmino · Korneuburg / Vienna
Paramedic instructor. Bird-ringing volunteer. ADHD brain. I’ve shipped software for all three of those worlds.
Currently: founder of mind-the-brain →
Care
Volunteer paramedic and instructor with the Austrian Red Cross.
Bird ringing
Volunteer at the banding table, ringing sessions in Illmitz.
Now
With mind-the-brain I’m building a platform that externalizes executive function: weekly planning with accountability partners, an AI assistant that catches overload before it becomes burnout, and a community that connects ADHD’ers with peers and specialists.
