Yurii H.

I’m a Senior AI/ML & Mobile Engineer with 14+ years of software engineering experience, specializing in AI-powered applications, LLM/RAG systems, AI agents, and mobile development. I combine deep production experience in mobile development with hands-on experience building AI solutions using Python, PyTorch, LangChain, LangGraph, vector databases, and LLM APIs. What I can help you build • AI-powered mobile applications • LLM-powered applications and intelligent assistants • RAG systems with vector databases and retrieval pipelines • AI agents and agentic workflows with LangGraph and LangChain • OpenAI and other LLM API integrations • Python-based AI/ML backends and APIs • AI integrations into existing mobile applications • Production-ready mobile applications • AI prototypes and MVPs from concept to production My technical background AI / ML: Python, PyTorch, Machine Learning, Deep Learning, Computer Vision, LLMs, Prompt Engineering Generative AI: RAG, LangChain, LangGraph, AI Agents, Vector Databases, Embeddings, Retrieval & Reranking, LLM Evaluation Mobile: iOS, Android, React Native Backend / Integration: REST APIs, Python, FastAPI, PostgreSQL, Vector Databases, OpenAI APIs I have extensive experience delivering software end-to-end — from architecture and implementation to testing, performance optimization, deployment, and production support. My background in mobile engineering allows me to build not only the AI backend, but also integrate AI capabilities into real production mobile products. If you need someone who understands both AI engineering and production mobile development, I can help turn your idea into a working product.
