I build and maintain n8n workflows that connect CRMs, lead sources, email, and messaging tools through REST APIs and webhooks. My work automates lead handling, from capture and enrichment through qualification and follow-up.

For client projects, I’ve developed LLM-powered workflows for lead classification, content drafting, information extraction, and customer-enquiry routing. I use structured outputs and human-review fallbacks to support reliable handoffs.

I also build AI agent systems with Python, FastAPI, and LangGraph, integrating LLM APIs with PostgreSQL-backed CRM data. In the AI-First Healthcare CRM project, I built a full-stack CRM with a seven-agent LangGraph architecture for lead and patient-enquiry handling.

I monitor executions, troubleshoot API errors, and document workflows as SOPs covering testing and maintenance. I manage delivery and QA across multiple client projects in remote settings.
