AI agents infra / MCP / RAG / multi-agent memory / orchestration
I architect and ship production systems: websites, platforms, Telegram bots, integrations. 13 years of engineering, 50+ projects shipped, clients in 12+ countries.
What's different is how I build now. I don't "use ChatGPT": I orchestrate a fleet of AI agents across multiple models and build their tooling myself - RAG over the codebase, memory of past decisions, architecture-aware navigation. My agents don't guess, and don't break what already works.
What I build for clients, I built for myself first and run on it daily. For you that's startup speed at production quality.
• AI agents - agentic systems, orchestration, MCP integrations
• RAG - semantic search over your data, code, documentation
• B2B SaaS - architecture, turnkey builds, CTO-as-a-service
• Automation - Telegram bots, mini apps, internal tooling
• Full-stack - TypeScript, Next.js, Node.js, Mongo/Postgres
• Web3 (8+ years) - Solidity, DeFi, NFT

I’m a senior backend and systems engineer with strong experience in AI integrations, blockchain infrastructure, automation, and complex API-driven platforms.
I focus on building reliable, production-ready systems — not just prototypes. My work includes AI-powered applications, custom agent runtimes, backend architecture, blockchain and Web3 integrations, trading and market-making systems, automation platforms, scraping pipelines, and custom internal tools.
My background includes building custom crypto market-making infrastructure, working on EVM blockchain setup and configuration, delivering off-chain and on-chain trading solutions, and leading technical execution across backend-heavy projects. I’m comfortable owning architecture, implementation, integrations, and the practical decisions needed to turn an idea into a working product.
Core areas I work in:
- AI and OpenAI/LLM integrations
- Backend systems and API architecture
- Python, Node.js, automation, and infrastructure logic
- Blockchain, Web3, and smart contract-connected platforms
- Trading systems, bots, and exchange integrations
- Data extraction and workflow automation
I work best with clients who need a developer that can understand the real problem quickly, recommend the right technical approach, and execute with minimal hand-holding.
