Senior iOS engineer helping teams build and ship production-ready apps.
Robert Harrison
Senior iOS Engineer • 15+ Years Experience
Former GoPro 15+ Years Mobile Architecture Fintech Health & Fitness Photo & Video
I design and build production-ready mobile apps, owning the process end-to-end, from architecture through launch and iteration.
Deep experience with video playback, editing pipelines, HLS streaming, and performance-critical systems.
Improve performance, reduce crashes, and simplify complex codebases so products can grow reliably.
Whether working solo or embedded with a team, I help make the right decisions, and implement them.
Define the problem, constraints, and what actually matters, before writing code.
Simple, scalable systems built for real-world use, not over-engineered abstractions.
Tight build → test → iterate loops to maintain momentum and reduce risk.
Clear async updates and focused discussions, no unnecessary meetings.
From early decisions to App Store launch, I stay involved until it’s working.
Real-world projects across media, fintech, and health. Focused on performance, reliability, and shipping high-quality apps.
