  6. Now

01 / What we can build together

Less friction. More room for your real work.

Connect AI to your work tools

Move information between your software and AI tools to avoid entering it twice and automate repetitive tasks.

Create specialised assistants

Turn your methods and rules into assistants for specific tasks, ready to use in your everyday tools.

Build tools for your team

Identify shared needs within and across your teams’ areas of work, then build tools they can use together and reuse.

Other uses are possible.

02 / Work together

One useful step. Then the next.

  1. Understand

    I take time to understand your business, how you work and what you need.

  2. Choose

    We prioritise key uses and define the results to measure.

  3. Build

    I build the solution. Together, we test it and put it to work.

  4. Support

    I help you get comfortable using it, then maintain and improve it as your needs evolve.

Your teams understand how the solutions work, approve important actions and measure what changes.

03 / For technical teams

Better AI practices, on your own code.

Working alongside your developers on your projects, I help them improve their practices. They build and maintain their tools while I guide them.

  • Tools and boundaries

    Set up the environment, data access and project rules.

  • Development practices

    Build reusable skills to give AI tasks specific to your projects, using your methods and tools.

  • Agents and progress

    Bring specialised agents together, with your teams approving important actions and keeping costs under control.

  • Go further

    Local, cloud or hybrid AI: choose the architecture that suits your needs. Design agents that can work towards an objective, with human approval checkpoints defined together. And other solutions to implement based on your needs.

04 / A direct relationship

The person who listens is the person who builds.

Since 2010, I’ve been developing mobile apps and the tools and services around them, designing their architecture and leading teams. This experience has taught me to turn business needs into reliable solutions and keep improving them.

For over a year, I’ve been using AI to design agents and tools that I work with every day to learn, organise my ideas and carry out my projects. They help me focus on understanding needs, making design decisions, the technical work and the quality of what I build.

Like mobile development, AI fascinates me through its impact around the world, across every sector. To make the most of this technological revolution and stay in control, we need to understand how it works and adopt it in ways that suit our uses.
