About Me
I am a senior iOS engineer with more than 10 years of production experience, and I currently focus on building full-stack mobile and AI-powered applications end to end. My strongest background is in native iOS development, where I work with Swift, SwiftUI, UIKit, AVFoundation, clean architecture, performance optimization, and App Store delivery.
I have expanded my work beyond mobile UI into full product ownership, including Firebase and Supabase backends, OpenAI integrations, GPU-based workflows with RunPod and Replicate, subscription systems, payment verification, and cross-platform development with Flutter and React Native. I enjoy taking products from idea and architecture through polished implementation, testing, release, debugging, and long-term iteration.
Most recently, I have worked on creator-focused social, chat, and media products, where I owned major features from architecture to release. I have built SwiftUI interfaces, integrated APIs, supported media upload and playback flows, and improved reliability in production environments with heavy video and caching demands.
Earlier in my career, I developed enterprise and business automation apps for international clients, building native iOS applications with Objective-C, UIKit, Core Data, and Apache Thrift. I also worked as a full-stack web developer on business systems using C#, ASP.NET, JavaScript, jQuery, HTML, and CSS.
I am comfortable working across the full mobile stack, including backend services, authentication, cloud functions, databases, and app monetization. I have experience shipping apps to both the App Store and Google Play, and I care deeply about production quality, maintainability, and user experience.
I work remotely and am open to relocation for the right opportunity. I bring a product-minded engineering approach, strong ownership, and a track record of delivering reliable mobile software for startups, founders, and product teams.

Independent senior mobile engineer delivering production apps for startups, founders, and product teams across iOS, Android, AI, subscription, utility, and media/video categories. Delivered end-to-end mobile products from scoping and architecture to polished UI, backend integration, testing, App Store release, and post-launch iteration. Built native iOS apps with Swift, SwiftUI, UIKit, Combine, AVFoundation, and clean architecture, with focus on performance and production quality. Integrated full-stack and AI features using Firebase, Supabase, OpenAI, Gemini, RunPod, Replicate, subscriptions, payment verification, and async media-generation workflows. Shipped and supported apps across the App Store and Google Play, including native iOS, Flutter, React Native, and Android products.
Worked on a creator-focused social networking product for link-in-bio, audience growth, analytics, monetization, and personal brand management. Owned the new chat feature from architecture to release, including SwiftUI UI, business logic, API integration, media upload support, and production polish. Helped translate product requirements into clear backend behavior and coordinated closely with a new backend engineer during implementation. Created a dedicated Mac test target with integration tests to catch API and business-logic issues earlier and reduce regressions. Improved reliability in a media-heavy social app, including video loading, caching, production stability, and behavior later used for Android chat integration.
Developed native iOS applications for enterprise and international clients, including mobile products with complex client-server workflows, local persistence, reusable UI components, and production release requirements. Built native iOS apps from scratch using Objective-C, UIKit, Core Data, Xcode, and Apache Thrift. Developed client-server mobile products for business, travel, and event-related workflows, including projects for Ural Airlines and Open Innovations Forum. Owned architecture and implementation of reusable UI components, local data handling, API integration, and production stability for enterprise mobile apps.
Worked as a full-stack web developer on business software for major clients, including Coral Travel and Luxor Group, building backend features, frontend interfaces, and database-driven internal tools. Developed backend features and business logic with C# and ASP.NET. Built frontend functionality with JavaScript, jQuery, HTML, and CSS.
