What I'm looking for

I want to build and scale iOS products end-to-end—shipping Swift/SwiftUI apps with strong API/payment integrations, real-time features, and measurable performance improvements, while maintaining smooth App Store delivery and fast, reliable releases.

I’m a results-driven Senior iOS Developer with 4+ years of experience building scalable, high-performance mobile applications using Swift, SwiftUI, and UIKit. I’ve delivered production-grade apps serving 100K+ users by architecting robust mobile solutions, integrating REST APIs, and optimizing app performance to ship on tight deadlines.

In my work, I’ve developed and deployed iOS RESTful APIs and payment systems (Stripe, Apple Pay), improving transaction success rates, and I built real-time features (chat and audio/video calls) using Agora SDK. I also integrated Firebase and AWS with CI/CD, reduced app latency by ~25% through strong REST API integration, and ensured App Store compliance—reducing the rejection rate to near zero.
