John Cosio
Independent Software Consultant.
I help businesses and startups build custom software, AI-powered applications, and SaaS products.
With over 15 years of experience, I enjoy turning ideas into working software — from internal business systems to customer-facing products.
I try to find the simplest approach that fits the problem, resources, and constraints.
No need for fancy buzzwords.
