Sami is a full-stack builder who ships AI and automation systems end to end — data model, backend, interface, and the AI layer that ties them together. The parts most teams split between four people, he does himself. A background in content creation and visual design means he judges the output the way the end user would, not just whether the pipeline ran without errors. He builds in public and would rather show a working version than describe one.
