The Daily Rhythm
When does power move? The duck curve, the daily spread, negative prices, capture price, volatility.
Software products,
shipped end to end.
Twenty years putting AR and planning software on factory floors, now in two products built with Claude.
Nine plain questions about European power, answered by 41 views computed in advance from open data on a fixed schedule. An assistant on every view answers questions about its charts.

the assistant · a suggested question, answered from the view's own figures
What's on the Grid
Generation mix, carbon intensity, residual load, the midday ramp-down, and when gas sets the price.
Geography of Price
Where power flows and why prices split, in Germany, France, the Nordics and the UK.
When the Grid is Tested
Dunkelflaute, batteries large and commercial, adequacy, and how far the day-ahead forecasts miss.
The Bill
What flexibility is worth, and how a megawatt-hour becomes your monthly bill.
The Charge
Where Europe's cars and first electric trucks plug in, what a charge costs, and how much of the network is built.
The Load
Data centres, a flat line for a decade until AI: what they draw, what a token costs in energy, and who gets connected.
The Build-out
What gets built, and how fast: solar and wind capacity, how much of the year it runs, and how much energy arrives as electricity.
Country by Country
Fourteen power systems, each with its own fuels, price zones and answer to the same problem.
One number for the business: 100 points across quality, value and moat. Around it, a score-free read on sentiment, IPOs and events. Each score shows its working: the figures behind every pillar, and how complete the data is. It is retired for now; the screenshots show it as it last ran.

I describe what I want and answer the questions that sharpen it. Claude writes the spec, and when I say go, a crew of agents builds it issue by issue. A second model reviews every pull request and merges what passes. I say go once more to release it.
From intent to production
Spec
Claude questions me, then writes the spec and issues. I say go.
Dispatch
A script with no model starts workers as issues unblock
Build
Sonnet workers in parallel, one worktree each, tests first
Review
A fresh Opus session merges or sends the work back
Release
CI tags, deploys and checks the live site. I say go.
One kit, one server
A shared kit puts the same skills, hooks and release workflow into every repo, and a drift check catches local edits. Every session runs on one home server, and I steer them from a laptop, a tablet or my phone. Opus writes the spec, reviews and judges; Sonnet workers write the code.
A task manager watches every run, and what it can't settle gets parked with a reason. An LLM council of four models checks the spec and risky merges. Progress lives on GitHub: each milestone closes when it's done, and a live board shows every issue.
Behind it, a testing gate on every session: failing-first tests, pre-commit hooks, detect-secrets. Wattlas alone carries over 5,600 tests.
Two pipelines
Releases: one word, five jobs
My go opens a release PR. Its merge starts one workflow that tags the commit, publishes the notes, deploys, smoke-checks the live site and closes the milestone. No session pushes a tag.
go → tag → release → deploy → smoke check → milestone
Wattlas: a cron, a commit, a redeploy
A scheduled job reruns the Python pipeline on the 1st and 15th at 05:17 UTC, commits only the JSON that changed, and the static site redeploys. Each open data feed is isolated and fails open.
open APIs → pipeline → data/*.json → redeploy
The two products above are the current chapter. Before them came augmented reality out of a research lab and into car plants, a German company to run, and the work I do now: leading a consulting team at Dassault Systèmes that connects manufacturing planning to what happens on the line.
It is told as six frames on a wall. Each one is faint pencil until you open it, then it inks itself in. The sixth is blank: you write the next one, and it arrives in my inbox with your line already in it.
Six frames
The lab years
Weimar, Bordeaux, Tokyo. How should people handle 3D content without a mouse? Five papers and a doctorate later, factories wanted the answer.
From prototype to product
Paris. Leading R&D at Diota, turning AR tracking research into something that survives factory light and moving parts.
Running the business
Stuttgart. Taking over the German company: P&L, hiring, and learning exactly what a business case must look like before anyone signs.
Where planning meets the floor
Dassault Systèmes. Leading the DELMIA Augmented Experience consulting team, connecting the digital twin to the people doing the work.
The independent practice
The two products above, designed, built and shipped end to end, with AI doing the typing and a human keeping the gates.
The next frame
Empty on purpose. Write one line into it and it becomes the start of a conversation.
