Ifiok Columba

I’m Ifiok Columba, an entry-level AI Automation Engineer focused on building practical, end-to-end systems with n8n and modern LLM tooling. Over the past few months, I’ve designed and shipped multiple automations—ranging from an agent that books and manages consultations via natural conversation to pipelines for lead scoring/routing, invoice extraction, and anomaly detection.

I’m especially interested in grounded AI: I build RAG support bots that retrieve from real documentation and respond only when the answer is supported. I typically own the whole stack—from ingestion and storage (PostgreSQL/Supabase, including pgvector) to orchestration and integrations (Telegram, Gmail, Google Calendar, Google Sheets, Slack)—and I emphasize reliability by enforcing critical rules in the data layer so the system is structurally correct, not just “model-reliable.”
