Pejman Azizi

I lead the technical side at Hand On Web — voice AI (ElevenLabs + Retell + Vapi + Synthflow), retrieval-augmented chatbots, and the n8n automation stacks we build for UK clients. Before joining, I spent years shipping production systems and learnt the hard way that the hardest part of enterprise AI is not the model — it is the 47 edge cases, the GDPR policy, the human hand-off, the monitoring when it breaks at 2am. I write here about the trade-offs behind the glossy demos: what actually works for a 4-chair dental practice, what fails in a Scouse accent, why your Zapier bill will double this year, and how to keep a voice agent from hallucinating a price.
