Summary
I build AI workflows in n8n with OpenAI and Claude APIs and connect them to CRMs
through REST APIs and webhooks. My workflows run in production for real clients, with
error handling, retries and a human approval step where it matters. Before automation I
worked as a developer and in technical support.
Skills
n8n: complex scenarios, webhooks, JSON processing, API integrations, error handling,
retries with backoff
LLM: OpenAI API, Anthropic Claude API, prompt engineering, classification, structured
output, Claude Code
Integrations: REST API, JSON, XML, HubSpot, Attio, Lemlist, Slack, Google Workspace,
WhatsApp (TimelinesAI), Aircall, Fireflies
Programming: Python, JavaScript, SQL, PostgreSQL, Supabase
Tools: Make, Git, GitHub, Linux, Postman
Experience
AI Automation Engineer, Freelance | Remote | Jan 2026 to Present
Built n8n workflows for B2B clients where an LLM classifies incoming replies, the CRM
gets the contact and deal, and the team gets a Slack alert.
AI marks new deals as suggested and the team approves or rejects them before
anything changes.
Built LLM scoring of website visitors from scraped website and LinkedIn data, with
structured output and fallbacks when data is missing.
Added caching, retries with backoff, deduplication and guards for empty data to keep
API costs and errors down.
