If you invite or message me, I’ll send a short personalized Loom on how I’d approach your exact workflow.
I help businesses stop manual document work and ship production AI systems: multi-tenant knowledge apps, invoice/document agents with audit trails, and n8n workflows that write to Sheets, Slack, or your tools.
• Multi-tenant RAG SaaS — org isolation, RBAC, chat with sources
• AI Workflow Agent API — extraction, tool calling, full step logs + cost
• n8n intake — document in → Agent API → Sheets + Slack
• Top Rated, 100% Job Success and reply within 0–4 hours
• Strong overlap with EU mornings and US afternoons (UTC+3)
I build custom FastAPI + Next.js systems and glue them with n8n — not fragile no-code-only demos.
Also strong with Flutter when you need a mobile client on top of the API — secondary to AI/backend work.
Not a fit if you need ML research, model training, or a cheap chatbot with no deploy plan.
