Hi, I’m Aries.

Small apps, made for fun and for real life.

Brewing iOS apps since 2018

About

I’m a senior iOS engineer with 8+ years of building for iPhone — mostly in Swift, UIKit and RxSwift, with some Objective‑C kept running along the way. Right now I’m taking a breather: exploring SwiftUI and building small side projects, apps that make everyday life a little more fun.
