Summary
Bruno Koga is a Senior iOS Staff Software Engineer with 13 years of experience building high-quality, secure mobile apps and leading engineering teams from startup to scale. Based in Amsterdam, he has been the driving force behind Siilo’s iOS product since its inception, implementing core features like end-to-end encrypted messaging, secure local storage, and audio/video calling used daily by hundreds of thousands of healthcare professionals. He combines deep Swift expertise (RxSwift, Combine, UIKit, SwiftUI) with hands-on experience in encryption (NaCl) and low-level networking to architect resilient, privacy-first systems. At Doctolib he now steers technical direction and cross-team coordination for the Siilo app, while mentoring engineers and shaping hiring and onboarding processes. Known for turning first-principles engineering into product-ready features, he also brings a history of international consultancy and developer education from roles at CI&T and other fast-moving teams. Quietly obsessive about craftsmanship, he often surfaces elegant, system-level improvements others miss.
