Three connected apps: an admin back office for Flying For You's staff, a reporting portal for its customers, and a React Native field app. In production for over two years, still shipping.

Mission management, live GPS tracking, interactive maps, and KPI dashboards. A Python simulation API runs underneath, using French geographic and INSEE demographic data.

Google Maps could not render the vector tiles it needed, so I wrote google-maps-vector-engine and rebuilt the pipeline around it. Processing time dropped 60%.

I own CI/CD and the deploys.

Google Maps has no native support for Mapbox Vector Tiles. This renders them as PBF tiles on Google.maps Map, with fast feature lookups, click selection, and styling you can change at runtime.

MIT on npm, running in production on Flying For You.

TallyGrid is a logic puzzle game on Google Play that is really a constraint solver with a board attached.

Every generated board is proved to have exactly one solution, using an exact solution counter with constraint propagation and backtracking. A second solver works only from human deduction rules, which is how the game guarantees you never have to guess.

Difficulty scores and hints both fall out of that solver, so a hint shows you the next deduction instead of the answer.

Leaderboard is offline-first: scores queue locally and sync on the next launch.

Takes a project brief and returns a structured agile backlog: user stories, tasks, features. Editable before it goes anywhere, then one click into ClickUp.

Built the generator and the prompt logic behind it. Planning time down 50%.

Reviews GitLab merge requests over webhooks. Flags bugs, rates quality, posts the feedback back on the MR.

95% detection accuracy at hundreds of PRs a week. Prompts and token budgets tuned so big diffs get reviewed without falling out of context.
