The project index

Ideas into working systems.

Eight systems built. One in development, and three planned explorations in conversational AI, automation, and reliable agent behavior.

Every project has a walkthrough — the reasoning behind it, stage by stage, including what would have to hold true for it to work.

Developer toolingVoice AI Workflow BuilderFrom a natural-language requirement to a validated, platform-neutral automation workflow.In DevelopmentFull scope
Customer supportENTIN Bank AI Voice SupportA voice agent for a fictional Nigerian bank that handles failed transfers, card disputes and fraud — with identity checks and risk rules enforced in the workflow, not the prompt.Full scope
Reliability engineeringAgent PreflightA pre-production check for a voice agent’s webhook tools and the n8n workflows behind them. It prints what will break, and fails the build when it matters.Full scope
Reporting & QA operationsVoice Agent Reporting HubA reporting system that turns raw voice-agent call logs into client-ready weekly reports — built for a voice AI agency and used on real client accounts.Full scope
Lead qualificationOriki Homes: Real Estate Speed-to-Lead AgentAn AI assistant, Joy, who answers a Nigerian property enquiry in under a minute on WhatsApp or by live voice, qualifies the buyer against a tested scoring rubric, and alerts a human the moment a hot lead appears.Full scope
Appointment schedulingInbound AI Appointment Booking AgentAn inbound voice agent that takes the caller’s details, checks the calendar in real time, books the slot, and texts a confirmation.▶ DemoFull scope
Lead qualificationOutbound AI Lead Qualification AgentAn outbound voice agent that calls a real-estate lead, introduces the service, qualifies them on budget, timeline and property preferences, and writes every answer to a sheet.▶ DemoFull scope
Voice AIFairy Share Dental AI ReceptionistAn inbound dental receptionist that books into the practice management system — and only says “booked” after it has read the appointment back and checked every field.Full scope
Reliability engineeringVoice Agent Regression HarnessA proposed replay harness that runs recorded calls against a new agent version and blocks the release when behaviour regresses.PlannedFull scope

Voice performanceLatency & Barge-in LabA proposed measurement rig for where the seconds go in a voice turn, and how cleanly the agent handles being interrupted.PlannedFull scope
