Rockstar🎓
Top SchoolAndrej Mihajlov is a seasoned software leader with 15 years of hands-on experience building cross-platform VPNs, mobile apps, and web frontends, currently serving as Head of VPN Engineering in the United States. He blends deep iOS expertise (Objective-C, Swift, network extensions) with systems-level Rust work and TypeScript-driven front-end engineering, having shipped production WireGuard integrations and a Rust VPN service used across desktop and mobile. His background includes building an iOS app from scratch at Mullvad, architecting a multi-process Rust/Tauri VPN MVP, and leading teams to rapid delivery while hiring and mentoring engineers. An active open-source contributor, he has improved widely used repos like flow-typed, DefinitelyTyped and Konva, and made substantive contributions to wireguard-apple and WireGuardKit. Notably, his early indie work on HTML5 children’s games evolved into a small game engine solving aggressive caching and rendering challenges—evidence of both product focus and low-level performance instincts.
