QuantumEye — a computer-vision platform for retail loss prevention, deployed across UK retailers. Plus a steady stream of smaller experiments collected at erpik.com/lab: AI tools, agents, music, scripts.

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 — Product design and technology consultancy for teams that ship. Most consultancies are paid to deliver decks. Most product teams are paid to deliver products. There's a gap between strategy and execution that gets papered over with handoffs. Purple Luna is what happens when you refuse to do that — when you write the strategy, the design, and the production code yourself, and the founder who hired you ships next quarter instead of next year.
