Top SchoolSergei Balashov is a Senior iOS Developer with nine years in software engineering and over seven years focused on Swift-based iOS apps. Based in Lisbon, he has shipped consumer-facing products from startup marketplaces to Russia’s top e-grocery app, working across architectures like VIPER, MVVM, and SwiftUI with Coordinators. He’s comfortable both building apps end-to-end—CI/CD with fastlane, analytics integrations, App Store delivery—and contributing in large teams with Gitflow, code reviews and unit testing. Past projects span real-time features (WebSocket, WebRTC), RxSwift-driven reactive stacks, and high-cadence Agile delivery. He combines hands-on implementation with an eye for product quality and observability, having introduced analytics and testing practices at early-stage companies. Colleagues would describe him as a pragmatic engineer who bridges startup speed and production-grade discipline.
