Projects
Systems built for real clients.

Tax integration between Shopify and CloudInvoice
A TypeScript Worker that turns every paid order into a tax document in CloudInvoice, with idempotency, on-demand customer and product creation, and stock deduction.

WhatsApp automation for a CRM, with AI doing the classification
A Python script that reads conversations through the Evolution API, classifies them with the Anthropic API and feeds the CRM on its own every morning, with database and processing on the machine itself.

Made-to-measure product configurator
Formula-based pricing on the product page, a variant created on the fly through the API so the item goes through the store's normal checkout, and shipping quoted live at the carrier.

Multi-tenant SaaS for websites
A FastAPI platform where each client has an isolated site, catalogue and admin panel, with regression tests making sure one tenant never sees another.

Website with its own admin panel and continuous deployment
Astro generating static pages, a PHP/MySQL API with a React admin panel, and publishing that triggers the build on its own through GitHub Actions.

Qualifying a lead base from open data
Brazil's public company registry processed in Python until it became a useful list. Along the way, the discovery that the data did not serve the use I had imagined for it.
