Paulo Coutinho
I'm a product-minded engineer and technical leader focused on mobile, architecture, and execution. I work hands-on across the full lifecycle of digital products—from technical direction to delivery—with strong experience in iOS and Android using Swift and Kotlin, and C++ when native performance, low-level control, or tighter platform integration matter. My work extends beyond the app layer into APIs, infrastructure, integrations, performance, and distribution—the technical foundation required to ship and sustain real products at scale.
As Co-founder of Ubook, I led mobile, architecture, and performance across one of Brazil's leading audiobook and spoken-audio platforms. I was directly involved in building the product from its early stages through growth, international expansion, and a funding round that helped scale the business. It was a hands-on experience in building a real product company—balancing technical quality, product evolution, scale, retention, and long-term execution.
I also maintain open source libraries and long-term engineering projects with the same discipline I apply to production systems: clear architecture, sustainable maintenance, and practical performance. My work spans native stacks, web tooling, and AI-adjacent systems, always with a focus on reliability, longevity, and engineering clarity.
Alongside product and platform work, I build and publish my own apps and games under my own name, with full ownership across architecture, development, and distribution. That independent work reflects a core strength in how I operate: the ability to build, lead, and ship software end to end—with autonomy, product judgment, and strong technical depth.
At a glance
- Leadership: I co-founded Ubook, a leading audiobook and spoken-audio platform in Brazil, with hands-on ownership of mobile, architecture, and performance from early product through scale and international expansion.
- Open source: I maintain libraries and tooling across native stacks, web, AI-adjacent systems, and Godot at the same standard as production work: clear architecture, practical performance, and changes teams can sustain over years.
- Teaching: On Udemy I teach native Android and iOS development with a shared C++ core across both platforms.
