Need an AI agent that works reliably in production—not another fragile demo? I’m a Top Rated AI Agent & RAG Engineer with 100% Job Success, $20K+ earned, and 29 completed and ongoing Upwork jobs. I build production AI agents, RAG knowledge systems, MCP tools, Telegram bots, workflow automation, and scalable Python/FastAPI backends. I help businesses turn manual processes or vague AI ideas into systems that can run unattended, call APIs and tools, validate outputs, recover from failures, and hand work back to a human when needed. Recent product work: • Halgo — an AI tutor workspace that indexes learning content and generates personalised homework. • mySkua — a Telegram growth and analytics platform supporting around 4.7K users, with attribution, segmentation, campaigns, broadcasts, and analytics. • Production automation projects involving browser workflows, structured data extraction, APIs, document processing, and internal AI tools. What I can build: • AI agents and multi-agent workflows • RAG systems, vector search, and knowledge bases • MCP servers and agent-facing tools • LLM integrations using OpenAI, Claude, and OpenRouter • Python/FastAPI APIs and backend services • n8n, Make, CRM, and workflow automation • Telegram bots and Mini Apps • Browser automation, OCR, and structured document extraction Typical stack: Python, FastAPI, OpenAI, Claude, MCP, LangGraph, LangChain, PostgreSQL, Redis, Docker, Playwright, vector databases, REST APIs, webhooks, n8n, and Telegram API. Production reliability is part of the build: structured outputs, JSON Schema validation, retries, fallbacks, logging, monitoring, permission boundaries, human handoff, and maintainable architecture. Send me your current workflow, data sources, and desired result. I’ll help identify the fastest practical first version and the risks worth solving early.
