Senior Software Engineer · Mobile & Front-end
I build the apps that live in people’s pockets.
I’m Bruno Amorim, a software engineer from Campinas, Brazil, currently on the front-end team at OpenXpace AI. Over the last five years I’ve shipped products end to end: an airline’s digital account, a white-label platform behind 40+ banks, a student bank — and, after hours, my own products: igreja.studio, a white-label for churches, and QWIP, a SaaS for gas stations, designed and built entirely by me.

Real-time 3D · WebGL
Turn the knobs.
How I split my time, as a piece of studio hardware. Nothing here is a downloaded model: the case, the knobs and every marking on the panel are drawn in code. Drag a knob up or down.
Own products
Built after hours, owned end to end — design, code, infra and the store listing. Every decision here is mine.
01 · FloatTube · own product
FloatTube
A YouTube mini player for the Mac that stays put while your desktops slide.
Chrome's picture-in-picture window jumps every time you switch desktops on a Mac. FloatTube replaces it: a menu-bar app in Swift and AppKit that plays the video in a floating player living in its own WindowServer Space — so it doesn't move a pixel during the Space animation — plus a Chrome extension that hands the video over when you leave the tab and back when you return.

Don't Idle
A native macOS app that keeps your Mac — and your status — awake.
A menu-bar utility that nudges the pointer when you step away, so your Mac stays awake and your chat status stays active — on a schedule, and easy on the battery. Built in SwiftUI and shipped as a notarized Developer ID app with a self-update flow and three languages.

03 · igreja.studio · own product
IEQ MVA
A whole church in one app — the flagship of igreja.studio, my white-label for churches.
IEQ MVA is the first church running on igreja.studio, the white-label platform I built for churches. No decision here belonged to anyone else: requirements with the church, every screen in Figma, Expo app, NestJS API, Azure infrastructure and both stores.

04 · QWIP · own product
QWIP
A whole gas station operation, readable from a phone.
My own SaaS: a multi-tenant financial management platform for gas stations. Reports, indicators and asset tracking — one NestJS backend, a Next.js web app and an Expo app, all built and shipped by me.

Company work
What I built inside product teams — from a 40-brand white-label to digital banks in production.
01 · Gol Linhas Aéreas · via MB Labs
PaGol
The digital account that turns balance into miles — and miles into travel.
Gol Airlines’ digital account, where your balance earns miles every business day. I worked on the border between native and React Native: critical modules in Swift/UIKit wired into a shared RN codebase.

- UIKit
- React Native
- TypeScript
02 · MB Labs
Bankeiro
One codebase. Forty-plus banks.
The white-label banking platform behind 40+ brands — PaGol, Localiza, Syngenta and others. I owned the front-end side: architecture, standards, code review and the pipeline that shipped dozens of apps to the stores.
- Next.js
- React Native
- TypeScript
- Node.js
- AWS
- Fastlane
03 · B.uni
b.Uni
The digital bank that fits a student’s life.
A digital bank focused on university students. I was the engineer responsible for both ends of the product: the React Native app and the React internet banking.
- React Native
- React
- TypeScript
- Redux
What I stand for
Detail is a requirement
Empty states, haptics, the way a receipt slides in. Nobody writes these in a ticket — users feel all of them. I treat polish as part of “done”, not as a luxury for later.
Performance is UX
An app that stutters is an app you don’t trust. I profile before I guess, and I optimize for the entry-level Android in someone’s pocket, not for the simulator on my Mac.
Design is a decision, not decoration
I open Figma before the editor. When I built a product alone, every screen was drawn, discussed and validated before a single component existed — because changing pixels is cheap, changing shipped flows is not.
Own it to the store shelf
My job doesn’t end at the pull request. Signing certificates, store listings, Apple review answers, CI/CD — shipping is part of engineering, and I’ve done it for dozens of apps.
