Summary
Product-minded Senior Native iOS Engineer and AI-Native Developer with 6 years of end-to-end delivery (idea → UX → architecture → implementation → release). Shipped 16+ own apps to the App Store and delivered multiple commercial products for iOS/iPadOS/macOS/watchOS. Designs and ships autonomous AI pipelines that dramatically accelerate development and automate business processes — with a focus on ROI and Time-to-Market. Strong in building high-performance, reliable, real-time apps and in AI-driven automation of release, localization, and content workflows.
Core strengths
- Scale & reliability: high-load products, performance tuning (Instruments), crash-free improvement 80% → 99.9%, clean architecture (SwiftUI/UIKit, Combine/RxSwift).
- Real-time & integrations: WebSockets, complex networking, external APIs (incl. Binance API / market data), offline-first & sync patterns.
- Release & growth automation: internal tooling around App Store Connect API (auth, metadata export/import, app/version management, localization + screenshots upload), fastlane workflows.
- Localization engineering: codebase string search, automated key generation, updates to localization files, refactoring hardcoded strings to localized APIs.
- Deep platform work: Metal shaders, camera/editing pipelines, .pkpass tooling with on-device signing (OpenSSL in Swift).
- Leadership: led teams up to 6 engineers, mentoring, cross-functional coordination (iOS / backend / design), delivery ownership.
- AI & Automation: designed autonomous AI agents on n8n + Claude, cutting internal product Time-to-Market by 3×. Built a Threads social-media scraper (n8n + custom JS) with automated video generation. Uses ComfyUI with fine-tuned models for content-factory video production. Orchestration: n8n, CrewAI. LLM environments: Codex, Claude Code, Antigravity.
