Pix do Casal

SaaSPaymentsMulti-tenant

Wedding gift registry platform with PIX payment integration, custom domain purchase, and multiple site templates. Couples create beautiful gift pages in minutes.

Pix do Casal was born from a real problem: traditional wedding registries are boring, rigid, and full of items nobody wants to buy. The idea was to create a platform where the couple builds their own page, picks a template, and guests make PIX payments directly toward whatever gift they choose — no middleman, no hidden fees.

Technically, we needed to solve per-user custom domains (multi-tenant), integration with the PIX instant payment system via banking API, and a template editor with real-time preview.

Split Poster

MobileiOSAndroidFreemium

iOS & Android app that splits large images into printable grid sections, exports a multi-page PDF, and handles in-app purchases via RevenueCat.

Split Poster solves a simple but frustrating problem: you have a large image (poster, map, artwork) and want to print it on regular A4 sheets to assemble on a wall. The app automatically splits it, exports a paginated PDF, and it's ready to print.

The technical challenge was on-device image processing (no server), multi-page high-quality PDF export, and implementing in-app purchases with RevenueCat for the freemium model.

E-commercePaymentsPerformance

Custom online store with custom checkout, inventory sync, and payment gateway integration — built for speed and conversion.

An online store built from scratch with total focus on conversion. The client was using a generic solution that loaded slowly and had a confusing checkout — cart abandonment was high.

We rewrote from scratch: single-page checkout, direct Stripe integration (no redirects), real-time inventory sync with the client's ERP, and a mobile-first interface that loads in under 1 second.
