I'm an AI consultant, self-taught developer, and writer. At Cigro I turn ambiguous requirements into SRS, software, and agent-native workflows, using focused skills, layered context, explicit tool boundaries, and evaluation loops. I started my first company at 18 with no paid advertising, then moved on to AI products used in university courses and client delivery. I care most about what happens after the first impressive demo: helping another developer understand what to trust, what to review, and how to turn one successful run into a repeatable workflow.
