🌍Top Rated Plus on Upwork - 27,622+ hours 🧠 Helping founders turn apps into AI-native products 🚀 15+ years shipping high-performance apps 📱 Built AI agents, automation systems & intelligent platforms ⚡ From scratch → scale → optimization About Me: I’m a senior mobile engineer with 15+ years of hands-on experience building high-performance iOS, Android, and cross-platform applications. Over the last several years, I’ve expanded deeply into AI-native systems including AI agents, LLM orchestration, generative AI infrastructure, and automated workflows. I don’t just integrate AI APIs — I design intelligent systems that reason, automate, and deliver measurable product value. I build apps designed from scratch, rescue unstable codebases, architect scalable systems, and implement advanced AI capabilities that transform standard apps into intelligent platforms. ⸻ 💡 Core Expertise Mobile Engineering • Native iOS (Swift / Objective-C) • Native Android (Kotlin / Java) • Cross-platform: Flutter, React Native, Unity (C#), Solar2D • Scalable architecture design (modular, MVVM, clean architecture) • Performance optimization & legacy refactoring AI Engineering & Intelligent Systems • AI Agents (task-driven, tool-using, memory-enabled architectures) • Multi-step LLM orchestration • Retrieval-Augmented Generation (RAG) pipelines • Embeddings, vector databases, semantic search • Prompt engineering & evaluation frameworks • Fine-tuning & structured output systems • Voice AI & multimodal pipelines (text, image, audio) AI Integrations • OpenAI APIs (GPT-4/5, Assistants, Realtime, Vision) • Image generation & avatar systems • AI-powered personalization engines • Conversational assistants embedded inside mobile apps • Streaming LLM responses & low-latency architectures Automation & Workflow Engineering • n8n workflow automation (AI-triggered pipelines, webhook systems, SaaS integrations) • API orchestration between AI models, CRMs, databases, and third-party tools • Event-driven backend logic • Automated content pipelines (generation → moderation → publishing) Backend & Infrastructure • Firebase, Supabase, AWS • Node.js APIs, REST, WebSockets • Real-time chat & streaming systems • Secure authentication & encryption layers • Subscription logic & monetization architecture Advanced Device Integrations • NFC ticketing & Wallet integrations • Bluetooth & IoT device communication • Smart TV remote control systems • Apple Watch extensions • Background processing & low-level OS integrations ⸻ ✨ AI & Product Highlights • AI Artist Pro — Subscription-based iOS app for generating AI art, avatars, and stylistic transformations using structured prompt pipelines. • Built AI-powered story engines, doodle generators, and educational assistants embedded inside consumer applications. • Designed AI-driven onboarding systems that adapt user flows based on behavioral signals. • Implemented voice-to-text → LLM → structured output pipelines for health and productivity apps. • Integrated GPT-based domain assistants across education, creative tools, and lifestyle products. • Developed automation workflows using n8n to connect AI models with CRM systems, content pipelines, and analytics platforms. ⸻ 🧩 Technical Stack Languages: Swift, Objective-C, Kotlin, Java, C#, JavaScript, Lua Tools: Xcode, Android Studio, Unity, VS Code Data & APIs: Core Data, SQLite, JSON/XML, REST, WebSockets DevOps: CI/CD, TestFlight, App Store & Play Store deployment Project Management: Git, Jira, Trello, Notion, Agile AI Tooling: Embeddings, vector stores, structured outputs, evaluation loops ⸻ 🚀 What You Can Expect • Senior-level architectural thinking • Clean, maintainable, production-grade code • AI systems designed for reliability, not demos • Clear communication and structured execution • Strong product intuition beyond pure engineering • Ownership mentality from concept to deployment I treat engineering as a craft. Architecture matters. Clean abstractions matter. User experience matters. I move quickly without sacrificing structure, and I focus on building intelligent systems that scale — not experimental features that break in production. If you’re building AI-native products, mobile-first platforms, or intelligent automation systems, I can help you design and execute them properly.
