About Me

My name is Kaykay Wise. I am a Senior Full-Stack Engineer & SaaS Founder with 14 years of experience in programming and software-as-a-service. I specialize in privacy-first, local AI agent architectures, automated B2B developer utilities, and building complete products from the first line of code to paid customers.

My work spans web applications, desktop software, blockchain contracts, AI tooling, and full SaaS platforms — including payment integrations, token-based access control, and behavioral profiling systems.
