Lead Product Designer & Design Manager AI-Native Product Design

I make and lead design from inside the team, not from the outside.

Thirteen years designing and improving products, six of them inside the client’s own product team: banking and insurance, legal tech and enterprise software.

    bugreports. New

    Personal product experiment · 2026
    My role: End-to-end product design and development with AI
    Deliverable: Working demo app

    A civic reporting system where a problem is filed with its evidence: a broken pavement, a street light that never comes on, a charging point out of service, a parcel that never arrived. A photo or a video, a location, thirty seconds.

    OBSS Apps

    OBSS Tech · Mar 2025 – Mar 2026
    My role: Lead Product Designer, then Senior Manager

    OBSS Ventures

    OBSS · May 2024 – Oct 2025
    My role: Lead Product Designer & Framer builder
    Deliverable: Live venture platform built in Framer

    A venture platform for OBSS Ventures: the portfolio, the investment criteria and the company stories. I designed it and built it in Framer, without a developer on the project.

    Hyve Chatbot

    OBSS · Jul 2024 – Jan 2025
    My role: Lead Product Designer
    Deliverable: Dashboard, chat and source verification screens

    A private, client-specific knowledge assistant. A chat product is easy to demo and hard to trust: the design problem was never the chat bubble, it was what the interface shows when someone needs to know where an answer came from.

    My role: Senior Product Designer

Tinkering

Built for myself, and for the company.

The only way to learn what works with AI is to build something and run it. Some of these sit inside the daily work; some are still being tried.

  • AI Automations for Brand and Marketing Building AI agents and automations for marketing processes. In development. In the works
  • 3D architectural visualisation Finding out how far AI has come in architectural and interior visualisation. Explored
  • Reading radar A skill that gathers the day’s reading around what I actually follow. In use
  • Era and Hera Two assistants: one for design and software, one for keeping track of the work. In use
  • My own plugins Packing skills so they install in a single command. In use
  • Persona agents Head of design, product manager, developer, each looking with its own eyes. In use
  • DEINS My own skill library: 15 chapters, 119 services. In use

You can write to me about the work, or about the things I make.
