I build backend systems for fintech, healthcare, and SaaS products where reliability is non-negotiable. My most recent engagement was a US broker-dealer fundraising platform serving 10+ institutional clients โ€” where I owned 5+ backend subsystems end-to-end for over a year, from schema design through Azure deployment.

Give me an AI document system or automation to build โ€” Iโ€™ll ship it so it runs for you 24/7. Thatโ€™s my promise. If you invite or message me, Iโ€™ll send a short personalized Loom on how Iโ€™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. โ€ข Multi-tenant RAG SaaS โ€” org isolation, RBAC, chat with sources โ€ข AI Workflow Agent API โ€” extraction, tool calling, full step logs + cost โ€ข n8n intake โ€” document in โ†’ Agent API โ†’ Sheets + Slack โ€ข Top Rated, 100% Job Success and reply within 0โ€“4 hours โ€ข Strong overlap with EU mornings and US afternoons (UTC+3) I build custom FastAPI + Next.js systems and glue them with n8n โ€” not fragile no-code-only demos. Also strong with Flutter when you need a mobile client on top of the API โ€” secondary to AI/backend work. Not a fit if you need ML research, model training, or a cheap chatbot with no deploy plan.
