Founder & Senior iOS DeveloperBangkok, Thailand8+ years in iOS development
Download CVI have worked in teams of two to twenty people, remotely and on-site, and spent three years leading teams. My work covers the full product cycle: shaping requirements, designing architecture, implementing the product, building test coverage and analytics, and automating delivery through CI/CD.
I specialize in SwiftUI, Swift Concurrency, modern declarative UI, and modular architecture with Tuist and Swift Package Manager. I also have hands-on experience with image and video processing, streaming, VoIP, subscriptions, and Swift backend development with Vapor.
Today I am building Winrate, a mobile and backend trading analytics platform for cryptocurrency exchanges. I also write technical articles, speak at meetups, and explore AI-assisted development workflows.
