Konstantin K.

An iOS developer and AI engineer who takes products from idea to millions of downloads. I built Struckd (12M+ downloads, acquired by Unity Technologies) and Daily Dozen (1M+ downloads, 4.9 rating, featured by Apple). 14+ years shipping production software. 30M+ client app downloads total.

Most developers write code. I handle the entire product lifecycle - architecture, development, App Store submission, ASO, growth, and ongoing support. You focus on business and marketing. I handle everything technical. Need someone to drop into an existing codebase and ship features? I do that just as well.

I work across two lanes - mobile and AI - and the overlap is where things get interesting:

𝗔𝗜 & 𝗠𝗟 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 - Image and video generation pipelines (Flux, ComfyUI), GPU inference deployment, LLM API integration (Claude, OpenAI), on-device ML (CoreML, Vision, YOLO8), AI agent workflows, RAG systems. I've trained and shipped custom ML models, built real-time object detection, and deployed generative AI backends on production infrastructure with Laravel and dedicated GPU servers.

𝗶𝗢𝗦 & 𝗺𝗼𝗯𝗶𝗹𝗲 - Swift, SwiftUI, SwiftData, UIKit, Combine since day one, with a large library of reusable components for fast shipping. Also Android (Kotlin, Jetpack Compose, KMP), cross-platform (React Native, Expo, Flutter), and deep work in HealthKit/medical apps, BLE hardware, fintech, AR (ARKit, SceneKit, Metal), and game dev (Unity, shipped titles at Unity Corp).

Growth is built in. I created ASOFast to solve App Store optimization at scale. I've gotten multiple apps featured by Apple and know the review process inside out.

Former CTO, Head of Mobile, and Tech Game Producer. Whether you need an AI-powered app, a standalone AI pipeline, or a polished iOS product - I ship clean, scalable work and think about the business value behind every technical decision.

Tell me what you're building, and I'll tell you exactly how I'd ship it.
