What's Sam like to work with?

Direct, fast, and hands-on across product, design, engineering, and go-to-market — which usually means fewer handoffs and shorter loops. UK-based, remote-friendly, prefers small teams where decisions ship.

Is Sam free for a project?

Currently yes — open for senior individual contributor roles, founding-engineer positions, or fractional CTO work. Email sameterpik@gmail.com or use the contact form at erpik.com.

Purple Luna

Purple Luna — An AI receptionist that runs the front desk for appointment businesses — on WhatsApp. Purple Luna spent years as a digital agency, building websites, products and digital experiences for small service businesses one bespoke project at a time. Good work — but it only ever reached the clients who could afford a custom build. Then AI changed what a small team could ship, so we did the obvious thing: we took everything we'd learned about serving these businesses and turned it into a product. Luna is an AI receptionist that answers your business's WhatsApp — the channel your customers already use — books appointments, takes deposits, and runs the front desk 24/7, in your own voice. The agency built one great experience at a time. Luna gives every salon, dental practice, clinic and gym the same thing, switched on in an afternoon.
