I help founders and teams turn AI ideas into working products in weeks, not months. Instead of spending months experimenting with LLMs, tools, and architectures, I design and build MVPs that actually work in real business conditions. Typical results: – Working AI MVP in 2–4 weeks – Clear, scalable architecture (not a demo that breaks later) – Reduced risk before investing into full development 💡 What I do best – Turn raw AI ideas into working MVPs – Design production-ready AI architectures – Build agentic AI systems (multi-agent workflows, automation) – Develop RAG systems & knowledge-based AI – Integrate LLMs into existing products and workflows I focus on execution and outcomes — not just code. 🧠 Who I work with – Startups validating AI ideas – Founders building MVPs for investors or internal use – Teams внедряющие AI в существующие продукты – Businesses looking to automate workflows with AI 💬 Not sure where to start? I offer short consultation calls where we: – break down your idea – define architecture – identify fastest path to MVP Most of my projects start this way. ⚙️ Typical engagement – AI MVP / Proof of Concept: $1,500 – $5,000+ – Architecture & planning: via consultation – Ongoing development: after MVP validation Most of my work is fixed-scope (MVPs, PoCs). If you need someone who can not only build, but also think through your AI product — let’s talk.
