I've built and maintained live n8n pipelines for CMI Kolkata that script, voice, render, and publish short-form video using LLMs. I handle scheduled jobs, webhooks, Google and Meta OAuth, error recovery, and execution monitoring.

I also built Saathi, an eldercare voice check-in system using n8n, Vapi, Twilio, and Supabase. It creates personalised call scripts, processes end-of-call mood and medication data, flags distress, and sends urgent or routine WhatsApp messages.

For automated video publishing, I've connected Groq, OpenAI, Gemini, Shotstack, YouTube API, Gmail, and external research APIs into end-to-end workflows. I built multi-provider variants to manage cost and avoid dependency on a single LLM provider.

My developer background means I debug APIs and data structures, not just workflow nodes. I write JavaScript, TypeScript, and Python for custom logic, and I build with reliability through retries, monitoring, documentation, and structured error handling.
