I am a Senior iOS Developer with strong experience in Swift, SwiftUI, and UIKit. I build App Store–ready iOS applications, fix critical bugs, and improve performance and UI without breaking existing functionality. I’ve worked on real production apps used by end users, helping startups and businesses turn ideas into reliable products. My experience includes Firebase, REST API integration, and clean, scalable app architecture. I focus on clear communication, maintainable code, and delivering results on time. If you’re looking for a dependable iOS developer who understands both technical quality and business needs, I’m ready to help.

Most clients come to me after a bad experience. A developer who went quiet mid-project. An agency that looked great on the call and disappeared after the deposit. Or they're posting a job and genuinely don't know how to tell who's worth trusting. I get it. Hiring a senior iOS/macOS developer or AI developer you've never met, for a product that actually matters to you, takes a leap. So here's what I can offer instead of asking you to just trust me: - a 100% Job Success Score built over real client relationships, - a 7+ month active partnership with a SaaS client where I delivered 3 production apps, - and a track record where 70%+ of projects turn into ongoing work. Not because I pitch retainers, but because the work holds up. I specialize in native iOS/macOS development and AI-powered products. I take full ownership from architecture to deployment and stay invested in whether what I build actually moves your business forward. Core technical depth: - Native iOS & macOS development (Swift, SwiftUI) - AI-powered apps and intelligent product features - Python backends, APIs, Firebase, Supabase - Audio, vision, and NLP-based AI systems - Clean architecture built for long-term maintainability and scalability If you're building something serious and need a partner who thinks about your product the way a technical co-founder would, let's talk.

Whether you’re starting from scratch or have a project that needs some love, I focus on making things work beautifully — not just technically, but for the people using them. 𝑺𝒐𝒎𝒆 𝒕𝒉𝒊𝒏𝒈𝒔 𝑰 𝒐𝒇𝒕𝒆𝒏 𝒉𝒆𝒍𝒑 𝒘𝒊𝒕𝒉: ⊛ Debugging and improving app performance ⊛ Building new iOS features from idea to App Store ⊛ Refining UI flows and small interaction details that make an app feel right ⊛ Integrating AI or CoreML features into real products I can also design simple, functional UI layouts in Figma or create app elements independently — so if your project doesn’t have a designer, I can take care of that part too. I’ve worked on everything from social apps with audio playback to live-tour guides that play music near landmarks like the Colosseum — always keeping reliability and clarity at the core. And just as much attention I pay to my bullet list symbols, I'll pay attention to your app :) If you’ve got an idea you’d like to bring to life (or an existing app that needs a fresh perspective), 𝑰’𝒅 𝒍𝒐𝒗𝒆 𝒕𝒐 𝒄𝒉𝒂𝒕 𝒂𝒏𝒅 𝒔𝒆𝒆 𝒉𝒐𝒘 𝑰 𝒄𝒂𝒏 𝒉𝒆𝒍𝒑.
