I turn operational problems into working software. Six years in production across water utilities, energy, healthcare and telecom, building Python data pipelines, ArcGIS Enterprise dashboards, FastAPI and Node.js services and React/Next.js apps. On the side, I design brands and online stores end to end.
- Aegea (via Bizpoke). Geospatial analyses behind water and sewer expansion studies for one of the largest sanitation groups in Brazil, plus the data model and dashboards of its landfill biogas operation. A reusable GeoPandas tool I built cut a recurring workflow from 3+ hours to about 20 minutes.
- Miau Atelier. A cat furniture brand I created and run for the US market: brand identity, Shopify store with Stripe, Python automation over the Shopify Admin GraphQL API and an AI pipeline for editorial product photography. Case study
- Independent projects. Brand identity, e-commerce and custom software for clients in Brazil and abroad.
