Top SchoolDavid Hoerl is a seasoned Senior iOS Developer with 14 years of focused mobile experience and a broad engineering pedigree stretching from Bell Labs to startups and product companies. He repeatedly ships high-performance, graphics- and media-heavy iOS features—everything from 4K video pipelines and Core Image filters to camera-based diagnostic apps and zoomable image frameworks—while modernizing legacy codebases and introducing best practices. A long-time open-source maintainer, he has contributed deep CoreText fixes to the widely used DTCoreText project and repackaged PhotoScrollerNetwork as Swift Packages to embrace SwiftUI and Combine. Based in Matthews, NC, he blends systems-level thinking (MS in Electrical Engineering) with pragmatic app-level craftsmanship and a knack for squeezing performance out of complex UI and imaging code. Notably, he pivoted in recent years to update legacy OSS for modern iOS architectures, signaling both curiosity and a commitment to future-proofing mobile software.
