I'm Thiago Henrique Pereira Freitas, a mobile architect with 13+ years of building native iOS (Swift) and Android (Kotlin) applications across fintech, payments, and proptech — delivering everything from MVPs to production apps used by 60,000+ businesses. I thrive on shaping robust mobile architectures and delivering high-quality, scalable features that meet real-world needs. I specialize in MVVM with reactive/Observable patterns and CI/CD pipelines (GitHub Actions, Fastlane, Jenkins) to enable fully automated App Store and Google Play releases. I’ve led cross-functional teams through architecture, design, implementation, and code review, improved legacy codebases, mentored engineers, and reduced crash rates through proactive monitoring (Crashlytics, store analytics) and bottleneck resolution. I also implement solid testing strategies (Unit & UI tests) and bring a full-stack mobile foundation (REST APIs, multithreading/GCD, relational databases) to the table. I’ve delivered for US-based companies remotely as a long-term contractor.…I'm Thiago Henrique Pereira Freitas, a mobile architect with 13+ years of building native iOS (Swift) and Android (Kotlin) applications across fintech, payments, and proptech — delivering everything from MVPs to production apps used by 60,000+ businesses.
