Ruth Aju

I'm a freelance AI Automation Engineer (RuthBuilds) based in Nigeria. I build automation systems and voice AI agents for founders, agencies, and service businesses. The kind of stuff that actually works day to day, not just in a demo.

I mostly work with n8n, additionally Make, Zapier, Retell AI, Vapi, ElevenLabs, Supabase, and the OpenAI/Anthropic APIs.

Here are some of what I've built: voice agents that handle property inquiries and bookings for real estate clients, WhatsApp and web chatbots that hand off to a human when needed, a sales call analysis system processing thousands of calls a month, Phone number geo location verification system, Event management systems, CRM/booking automations that save clients hours of manual work every week, and lots more.

I've also built n8n templates that got approved on their platform. I started out in Biochemistry, not tech, so I care a lot about things actually working properly, not just looking good on paper.

Right now I'm open to freelance and subcontract work, especially voice AI, workflow automation, and anything involving AI agents.
