Building Pigui — a B2B platform for brands and retail stores
I build and ship product end to end — backend, infrastructure and the boring parts in between.
Most of my work lives in Pigui, a B2B platform for brands and retail stores: catalogs, store and branch data, a lead engine, and billing. Alongside it I run CIV Bienestar, a Flutter + FastAPI ecosystem deployed on Cloud Run.
Day to day that means Python and FastAPI, Flutter and Dart, Postgres and PostGIS, Google Cloud Run, and whatever else the problem needs — including a native macOS app in SwiftUI when I got tired of browser speed tests.
