🚀 iOS Developer | 6+ Yrs | Built for Scale, Designed for Users
🎯 Swift • Objective-C • Clean Architecture • UX-Obsessed
I don’t just build apps — I craft mobile experiences that perform, scale, and convert. With over 5 years of hands-on iOS development experience and 2 years at a fast-paced social media company, I know what it takes to ship apps that stand out in crowded markets.
Former mid-senior iOS developer at Data Wow, I’ve led feature-rich app launches from scratch, optimized legacy codebases, and collaborated cross-functionally to deliver seamless, high-impact mobile products.
What You Get:
✅ Clean, maintainable code (Swift / Objective-C)
✅ Deep focus on UX & performance
✅ End-to-end delivery (from prototyping to App Store)
✅ Fast, clear communication with zero guesswork
I'm now looking for full-time roles (remote/hybrid) where I can grow, build meaningful products, and contribute to companies that value excellence. Open to relocation for the right opportunity. My personal goal? Level up professionally while easing the financial weight off my family.
