About this gig

Need production-grade AI automations or stateful multi-agent systems built for real-world reliability?

I am an AI Automation Engineer with a proven track record of shipping end-to-end production systems for international companies and NGOs. I transform complex business logic into fail-safe, scalable AI workflows.


What I Build & Automate:

  • n8n & Workflow Systems: Autonomous business process automation, CRM sync, API integrations, and error-handled webhooks.
  • LangGraph Multi-Agent Systems: Stateful, complex multi-agent architectures for high-level decision-making and tool use.
  • Production RAG & Document Intelligence: Conversational internal document search, invoice parsing, and knowledge bases using OpenAI, Gemini, & Supabase.
  • Custom API & Database Integration: Connecting LLMs seamlessly into your existing stack, internal APIs, Slack, or Gmail.

Why Work With Me?

  • Enterprise-Grade Quality: Clean, modular code designed with Human-In-The-Loop (HITL) checks and error alerts.
  • Full Technical Handoff: You receive complete SOP documentation, node-level guides, and walk-through support.

Lets turn your operational bottlenecks into intelligent, automated systems. Message me before placing an order
