I help startups and product teams build polished, production-ready mobile apps - from idea and MVP to App Store / Google Play release, backend integration, AI workflows, and long-term maintenance. My strongest background is native iOS development: Swift, SwiftUI, UIKit, Combine, performance optimization, clean architecture, and pixel-perfect UI implementation. I've spent years building real production apps with video, chat, media upload, feeds, payments, subscriptions, Firebase, push notifications, and complex custom interfaces. Today I also build AI-powered mobile apps end-to-end. That includes mobile app development, backend architecture, API orchestration, async job systems, and integration with AI / GPU providers such as RunPod, Replicate, OpenAI, Gemini, and custom ComfyUI workflows. I have also published my own apps on both the App Store and Google Play, so I understand product development not only from the engineering side, but also from the founder/product side: release requirements, store review, monetization, UX decisions, iteration, and production issues. What I can help you build Native iOS apps with Swift, SwiftUI, UIKit, Combine AI-powered mobile apps for image, video, music, chat, and automation Full-stack mobile products using Firebase, Supabase, APIs, and serverless functions RunPod / Replicate GPU pipelines for long-running AI tasks LLM features using OpenAI, Gemini, structured outputs, tools, and automation workflows Cross-platform apps with Flutter or React Native when speed matters Native Android features when the product needs Android support App Store and Google Play release, subscriptions, payments, push notifications Video-heavy apps with caching, processing, playback, and performance optimization Existing app modernization, refactoring, bug fixing, and long-term maintenance Recent relevant work LinkMe - media-heavy social app. Took ownership of a new chat feature from start to finish, including SwiftUI UI, business logic, API integration, media upload support, and production polish. Helped a new backend developer with product/business logic, created a dedicated Mac test target with integration tests to catch issues early, and supported the flow later used for Android chat integration. DanceMe - AI video generation app built from start to finish: native iOS, Firebase backend, App Check security, App Store payment verification, RunPod serverless GPU jobs, and a custom workflow based on open-source video models(Wan2.2, SCAIL). Cosplay AI - Flutter-based AI photo app published on both the App Store and Google Play, using Firebase backend and RunPod as the GPU provider for AI image generation(Z-Image, Qwen-Image-Edit). SongClip - React Native AI music and video generation app using Firebase backend and RunPod GPU infrastructure for long-running music/video generation jobs(ACE-Step, Qwen3 , LTX). Combine Videos - complex native iOS video editing app with a highly custom SwiftUI + UIKit interface, native video editing workflows, performance-sensitive media processing, and Metal usage. Video Matching, Grabglide - mobile products involving media, matching, custom UI, and production delivery How I work I'm not just looking to 'complete tickets'. I care about the product, architecture, user experience, release quality, and long-term maintainability. I use modern AI development tools like Codex and Claude Code to move faster, but I rely on senior engineering judgment to keep the codebase clean, stable, and production-ready. My usual process is: Understand the product goal and technical risks Build a clean foundation and reusable architecture Ship fast iterations without sacrificing maintainability Test, polish, release, and support the product after launch I prefer long-term collaboration, but I can also help with MVPs, AI integrations, app store launches, production fixes, and technical rescue work. If you need a senior mobile engineer who can own both the app experience and the AI/backend integration behind it, I can help.
