Nancy Goyal

I’m a seasoned Lead iOS Developer and Senior Software Engineer with 10+ years of experience and 8.5+ years specializing in native iOS development—Swift, UIKit, MVVM/VIPER—and high-security multimedia applications for 40M+ users.

I’ve led cross-functional teams of 5+ developers, shaping architecture decisions, mentoring engineers, and delivering scalable iOS solutions. In production, I’ve reduced piracy by 90% and crash rates by 40% through stronger security controls and rigorous performance work.

I build and harden video-based experiences using Apple FairPlay DRM, PallyCon SDK, CloudFront Signed Cookies, HLS streaming, AVFoundation, and layered protections like jailbreak/frida detection and anti-screen recording/mirroring. I also drive stability improvements by resolving complex memory leaks and multithreading issues with Instruments, bringing crashes from 2% to 0.2%.

I apply Clean Architecture practices with SOLID principles, Dependency Injection, and system design/OOD, while keeping delivery dependable via CI/CD, release management, Agile/Scrum, and thorough code quality & review. I’ve also driven SwiftUI adoption (widgets and new feature screens) and delivered secure capabilities like PiP, background playback, and secure offline downloads, while previously contributing as a .NET developer on RESTful services.
