Ajharudeen Khan

I’m a Senior iOS Engineer with 10+ years building production-grade fintech and consumer applications in regulated, high-compliance environments. I specialize in mobile architecture, performance optimization, and modular system design—especially where secure, audit-ready delivery matters.

At Angel One, I lead development of core fintech features for a high-scale trading application using Swift Concurrency (Async/Await). I designed and shipped Set Exit (driving ~10% conversion uplift) and led Orderpad revamp with a Server-Driven UI architecture to simplify order flow and improve modularity and testability through Dependency Injection. I also centralized EDIS flow into a reusable module aligned with compliance requirements, while mentoring engineers and ensuring resiliency via profiling, structured error handling, unit testing, and TDD practices.

Previously, at Times Internet, I architected and owned a modular iOS SDK integrated into 20+ high-traffic consumer applications, achieving up to 96% reduction in SDK binary size. I unified ad formats into an extensible SDK architecture, improved integration effort by ~25%, and contributed to ~6% increase in advertising revenue. Earlier at Infogain, I reduced crash rates by ~90% through ARC optimization and defensive coding, and supported onboarding with SDK documentation, integration guides, and sample applications.
