At Árvore (EdTech) I merged 800+ pull requests in 8 months, from a 17× faster report query to an AI feature that reads handwritten essays. Creator of Leaf (open-source Notion-style editor) and Rampa (open-source accessibility CLI with LLM judgment), and contributor to Hive (open-source AI coding-agent workspace). I measure before and after every change and own features from schema to UI.
