Hi, I'm Mayco Faciolo, a
React Native Engineer|
from Córdoba, Argentina. I build mobile and web products that feel premium: React Native, Expo, Next.js and TypeScript, with the discipline of a tech lead and the obsession of a designer.

Apps I've shipped recently
Real products, not tutorials. Scroll through each one: the phone follows you and every point shows the screen it talks about.
GlassDex
Solo build · shipped to TestFlight · 2026
A Liquid-Glass Pokédex that works with airplane mode on.
Fan-made Pokédex for iOS 26, Android and web. Real Liquid Glass surfaces with expo-glass-effect, native UITabBarController tabs, and a persisted TanStack Query cache so everything you have seen once keeps working offline.
Client-side search by name or number, type filters that combine, generation filter, and glass cards tinted by the primary type. No spinner after the first load.
02
Detail pages with a parallax hero
Floating artwork, tap to flip shiny, the Pokémon’s cry on open, and a segmented About / Stats / Evolution / Moves layout that stays readable on small screens.
03
Stats that move
Animated stat bars, a radar chart drawn with react-native-svg, and defensive matchups computed from PokeAPI damage relations.
04
Evolution chains with conditions
Branching chains like Eevee, with the trigger for each step: stones, friendship, time of day, trades.
05
Team builder
Six slots, average-stat radar and the weaknesses and resistances your whole team shares, recomputed as you swap members.
06
Who’s that Pokémon?
Silhouette quiz with confetti, streaks and persisted accuracy. Filter by generation to make it harder.
07
Offline first, by design
TanStack Query persisted to AsyncStorage, expo-image disk cache for artwork, and downloadable per-generation packs from Settings.
Bastante intenso, la verdad. Me cuesta desconectar.

Tiene sentido que te cueste, después de un día así. Probemos algo corto: ¿qué es lo primero que notás en el cuerpo cuando pensás en mañana?
El pecho apretado, y la cabeza que no para.
Gracias por ponerle palabras. Vamos a soltar un poco eso: inhalá cuatro segundos, sostené cuatro, y

Invoice approvals for an accounting ERP, built like production.
