A full social + competitive platform for padel, designed, built, and shipped solo.
Overview
SMASH is a mobile app that brings padel culture into one place — a short-video feed, player matchmaking, ELO rankings, leagues, and tournaments. I took it from a blank Flutter project to a live, monetized app on the App Store, owning the entire product: design, engineering, backend, subscriptions, and App Store launch.
My role
Solo founder & full-stack mobile developer — product, UI/UX, iOS engineering, backend, and release management.
What I built
Short-video feed with autoplay, likes, comments, sharing, and moderation
Matchmaking — find games by level, format (1v1/2v2/4v4), and city
ELO ranking system with server-side calculation and city/level filters
Leagues & tournaments — round-robin fixtures, live standings, auto-crowned winners
Pro subscription — RevenueCat + StoreKit 2, region-localized pricing, "organize = Pro" model
Full ES/EN localization
Tech stack
Flutter · Dart · Firebase (Auth, Firestore, Storage, Cloud Functions) · RevenueCat · StoreKit 2 · Riverpod
Highlights
Shipped end-to-end solo — from architecture to App Store approval
Designed a clean, editorial design system (custom glassmorphism, motion, type)
Implemented auto-renewable subscriptions and passed full App Store review
Built a self-reinforcing product loop: find a match → play → rank → compete
Perfect
Thanks!

I am gathering cool references for my own work as a Motion Designer, and this one caught my eye this week.
Day 3 of 60-days-collecting-awesome-motion-design-references
I love the way this is designed, based on abstract shapes and concepts with a coding visual language that we are all already familiar with. This is a great reference in this modern era where we deal more and more with products and services that live on the internet, not on a physical product.
This animation was created by Odd Fellows in collaboration with Figma.
60 days of references is a serious commitment. Curious, are you mostly drawn to the same visual language each time, or does it shift a lot depending on the day?
