AI / Agentic Systems

From coding assistance to autonomous software delivery

Caio’s current focus is the evolution from simple AI coding assistance toward orchestrated agentic systems that can plan, execute, verify, document and preserve execution memory. His work explores how agents can become part of the software delivery lifecycle while still keeping human review, traceability and engineering discipline.
