Erd

Python engineer with 4+ years of hands-on experience building backends, automation pipelines, and intelligent bots. What I deliver: • AI Agents & LLM Integration: Autonomous agents with tool calling (MCP), RAG knowledge bases, and workflow automation using OpenAI, Claude, Gemini, and DeepSeek. • Telegram Bots: High-load bots with payment processing, CRM sync, database architecture, and custom AI chat assistants. • Data Scraping & Mining: Resilient scrapers for e-commerce, directories, and protected endpoints with clean structured export to Excel, Google Sheets, or PostgreSQL. • API Development: High-performance REST APIs built with FastAPI, Flask, and PostgreSQL, packaged in Docker for one-command deployment. I write clean, documented code and provide complete setup instructions. If any issue arises within the agreed scope, I fix it promptly at no extra charge. Open for fixed-price gigs and hourly milestones with crypto escrow.
