Anderson Vanzo

Building high-performance apps with React Native and Expo

hello there, my name is Anderson, and I'm a senior mobile developer with over 5 years of experience

> about me

I started my career in 2021, working as a full-stack developer at a software agency called "D3T Inovação Tecnológica", where I worked with Laravel and Vue.js building mostly e-commerce sites. three or four months in, I was moved to a mobile project with React Native, and that's when the passion hit and I decided to focus my career on it

my experience so far leans heavily into the "Native" part of React Native, I've built several SDK bridges for different POS vendors (such as PagSeguro and Zoop) and a fully native screen for "blazingly fast" performance in video calls with the Twilio SDK

I also have a lot of experience working with offline-first apps, using the best tool for each case (which usually ends up being SQLite)

> projects

in my personal projects I tend to do things differently from what I do at work, in the past that meant native apps with Kotlin or Swift, but now I'm mostly interested in more "low-level" things, so I'm building a lot with Zig and C

I basically only started saving my personal projects to GitHub recently, so there's not much to show, I built the older ones in a weekend and then forgot about them whether I finished them or not

Zig CHIP-8 Emulator

this is a work-in-progress, and the name says it all: I'm creating an emulator/interpreter for games written for CHIP-8

Zig Invaders

this is the first thing I ever built with Zig, it's basically a simple clone of Space Invaders
it only has one level, and I don't know, maybe I'll add more levels someday
