Product developer based in Curitiba, Brazil. I build complete tools, from the problem to the deploy: I understand what hurts for the people using it, measure the result and ship it to production. Before writing software I spent 8 years in operations at e-commerce and logistics tech companies (Mercado Livre, MadeiraMadeira), which is where the habit of measuring everything comes from.
Free platform to plan events from start to finish: contracts with payment installments, a timeline, guest lists with Excel import, a checklist with deadlines, a quote comparison tool and a drag-and-drop seating chart. Live in production (interface in Brazilian Portuguese), with a public demo that has fictitious data and a guided tour of every feature.

Turns any song into a drum lesson for an electronic kit: separates the drums from the rest of the track, transcribes every hit with AI, finds the grooves and opens a player with a MIDI highway that scores each hit in real time. Runs 100% locally. Accuracy measured on a public benchmark (kick drum F1 of 0.93 on full songs).
