Freelance AI trainer with hands-on construction and small-business expertise, evaluating AI responses against real-world costs and constraints.
What I'm looking for
As a self-employed contractor and small-business owner, I manage residential projects from customer contact through completion, estimating costs, sourcing materials, setting prices, and evaluating finished work. I draw on more than 20 years of practical construction and carpentry experience to assess whether methods and recommendations make sense in real-world conditions.
Through Branch Brook Bushcraft and my equipment and appliance resale work, I’ve researched products and markets, evaluated repair costs and resale potential, and made purchasing decisions with incomplete information. I’m seeking freelance AI training and evaluation work where I can identify errors or impractical recommendations, develop realistic business scenarios, and give clear, structured feedback.
