ChainAPI

Full-stack developer. Got frustrated with AI giving inconsistent code output on every run. Spent months figuring out why — turned out to be structure, not the model. Built a system of structured JSON schemas for Claude's tool_use and OpenAI's function_calling APIs that produce 90-95% consistent parse rates. Just launched my first product: 33 of these schemas covering backend, frontend, and integrations. Building in public here.
