Integration & Automation Engineer · n8n, REST APIs, LLM workflows

Integration and automation engineer with a founder's track record. I build the connective tissue between business systems — CRMs, booking platforms, payment providers, messaging bots — and automate the processes that run on top of them.

WHAT I DO
• Design and ship integrations over REST APIs and webhooks — idempotency, error handling, production diagnostics
• Build automation in n8n: triggers, data routing, scheduled pipelines, error branches
• Embed LLMs into business processes (Claude API, OpenAI API): structured output, classification, text generation
• Migrate data between live systems without losses — moved 50,000+ client records

SELECTED WORK
• Founder and technical lead of a CRM with online booking for beauty salons. 20+ client companies, 50,000+ end customers. The integration passed review and is published in the partner marketplace of a major CRM platform.
• Built a promo-campaign platform with four game mechanics, QR/link launches, contact capture and Telegram notifications.
• Ran international payments and currency exchange: 500+ clients, $20–50k monthly turnover, KYC/AML procedures, routing across country and bank restrictions.
