Senior🎓
Top SchoolBill L is a software engineer with 13 years of experience, currently focused on low-latency quantitative algorithm development at Old Mission in Chicago. He brings a strong iOS and systems background from internships at Meta/Instagram and Teladoc Health, where he engineered resilient WebRTC and media-sharing features for enterprise telehealth under high packet-loss conditions. Bill has repeatedly reduced latency and improved system efficiency—evident from Firebase redesigns that cut newsfeed refresh times and work on performance-sensitive mobile codebases. Comfortable across Swift, Objective-C, and backend integration, he blends front-end UX awareness with low-level engineering rigor. His career shows a pattern of shipping production-critical features in both consumer and mission-critical healthcare contexts, and he thrives on turning latency constraints into reliable, measurable improvements.
