Rafael
Escaleira
I help teams turn mobile complexity into simple, testable, scalable software. Currently leading AI adoption in engineering workflows at Globo.
Builder by instinct, engineer by choice
I'm Rafael Escaleira, an iOS Specialist based in Brazil. I design and ship native Apple products that scale — from clean architecture to polished interfaces.
Education
BTech, Computer Systems Analysis
BSc, Computer Engineering
Working principles
Ship first, polish after
Working software beats perfect branches. I ship small, learn fast, and refine with real usage.
AI writes fast. I decide slow
AI accelerates the craft; human judgment owns the consequences. Every line gets reviewed.
Design is engineering
Spacing, motion, and typography are technical decisions. A beautiful UI is a well-architected one.
Native first, always
Apple's APIs come before abstractions. No cross-platform shortcuts when the product deserves native.
What I do best
A decade of focused practice across the full iOS stack — from pixels to pipelines.
iOS / Swift / SwiftUI
Deep expertise building native iOS products with Swift, SwiftUI, and UIKit.
Clean Architecture
MVVM, Clean Architecture, SOLID, and separation of concerns.
Swift Package Manager
Modular codebases with SPM, internal packages, and versioned releases.
Modularization
Feature modules, core layers, and clear contracts that reduce cognitive load.
Testing & TDD
Unit tests, snapshot tests, and TDD discipline for confident shipping.
CI / CD
GitHub Actions, Fastlane, TestFlight automation with minimal friction.
Design Systems
Tokens, components, and design-engineering alignment between Figma and code.
Performance
Memory profiling, lazy loading, concurrency optimization, smooth scroll.
AI-Augmented Workflows
Using AI for documentation, code review, test generation, and standardization.
Technical Leadership
Code review, mentoring, standards, and cross-team alignment.
Where code meets orbit
Every product I ship sits at the center of a constellation: native craft, architecture, automation, and AI. This is how I think about building software.
Native first, orbit always
I do not treat mobile as a delivery channel. I treat it as a craft. Each skill in this orbit is a layer of the stack I work on daily at Globo and in my side projects.
Globo / Cartola FC
Currently leading iOS development for Cartola FC, the largest fantasy football game in Brazil — where performance, reliability, and native craft matter at scale.
Cartola FC
Globo · iOS Specialist · Present
Cartola FC is more than a game — it is a national ritual during the Brazilian football season. As an iOS Specialist at Globo, I work on the architecture, performance, and user experience of an app used by millions of fans every round. The challenge is not just shipping features; it is keeping a massive codebase healthy, fast, and ready for spikes of traffic right after each match.
Personal work
Side projects where I explore new ideas, tools, and craft without delivery pressure.
