CrystalExpress iOS SDK

High-Performance iOS Ad SDK for Mobile Video Monetization

At Intowow, I led the development of iOS CrystalExpress, a lightweight SDK built to deliver native video ads instantly and at scale. The SDK was optimized for performance and seamless UX, powering monetization for major mobile publishers.

Key Highlights

• Engineered and launched the SDK from scratch within 3 months to meet key client deadlines

• Delivered over X m HD video ads per day with near-zero latency

• Boosted ad click-through rates by xx% through smart caching and rendering optimization

• Successfully integrated with Taiwan’s #1 news app, serving millions of users daily

This project gave me hands-on experience balancing system performance, mobile UX, and business outcomes under aggressive timelines.
