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.

Projects
- NAGORI — PS1/PSP Emulator — shipped solo to the App Store: ~12k lines of Swift/SwiftUI, Metal renderer, gamepad-adaptive UI, StoreKit subscriptions, 6 localizations. Optimized two C/C++ emulation cores at source level — 1,217 lines of ARM64/NEON across 30 files (SIMD interpreter paths, hand-written vertex decoders, restructured instruction dispatch) — cutting CPU cost of demanding PSP scenes from 50–70% down to 27–39% of a core, measured on device with Instruments incl. thermal-state tracking. Diagnosed and fixed upstream open-source defects (init crash, cache-invalidation bug); patches prepared for contribution. Links: App Store
- Synery — AI companion on Telegram (Founding Engineer / Tech Lead), 0 → 2,000+ paying-capable users in 4 months. .NET 10 / PostgreSQL backend with an agentic LLM pipeline (Semantic Kernel, tool calling, long-term user memory) and a custom lifecycle-scenario engine; React 19 admin panel with segment query builder and broadcasts; Telegram Mini App billing, subscription payments, PostHog analytics, one-command deploy infrastructure.
- Kinovecher — Telegram bot + Mini App + web video streaming platform (Python/FastAPI, aiogram 3, PostgreSQL, React 19 + TS; solo, in production). Reverse-engineered a closed AJAX API and defeated three layers of bot protection: ASN-level banning (403 for every datacenter network — mapped clean vs. banned ASNs, migrated hosts, kept a proxy path behind an env flag), an Anubis proof-of-work gateway (<2 ms), and obfuscated stream URLs with IP-bound tokens expiring daily — resolved server-side at playback time, with parallel Range probes filtering out dead CDN edges. Series with voiceover/season/episode selection and cross-device resume (HMAC-validated Telegram initData / Login Widget). Links: Website
