PhysiqueAtlas

Sole developer — schema, RLS, Edge Functions, web app, mobile app, billing

A coaching platform for contest prep — so a coach stops running the most precise sport in fitness out of WhatsApp and a spreadsheet.

Gym Progression

Sole developer — Flutter app, local persistence, release pipeline

Focus Modes

Sole developer, building with Claude Code as a pair — feasibility research, zen-rule engine, Quick Settings tile, widget, schedules, and release

iPhone-style Focus modes for Android 15+. Each mode is a real system Do Not Disturb rule, switched from a Quick Settings tile, a widget or a schedule.

Built — internal infrastructure & unreleased

Reusable starters, multi-agent delivery tooling, client architectures, and private builds.

Architecture diagram: client requests flow from a read-only inbox through intake tickets, scoping and the 4 Gates (spec, plan, TDD, fresh-context review) to launch, enforced by agent hooks, build gates and Belgian compliance checks, on top of site-starter.

webdev-kit & site-starter

Sole architect & author — starter template, 8 shared agent skills, hooks, evals, quote engine

A zero-JS static site starter paired with a cross-agent plugin suite that turns intake, scoping, 4-Gate TDD, Belgian legal compliance, and fresh-context reviews into deterministic infrastructure.

Architecture diagram: NL and EN copy in YAML and Markdown passes a Zod copy guard, builds with Astro 7 and ships to Cloudflare Workers. Below it, three decisions: a Stage 1 to Stage 2 toggle in YAML, a build-time ban on protected Belgian titles, and PhysiqueAtlas mobile screens rebuilt in HTML and CSS with zero framework JS.

Bilingual Coaching & Connection Site

Sole designer & developer — bilingual architecture, compliance guardrails, PhysiqueAtlas showcase

A bilingual (NL/EN) editorial site and PhysiqueAtlas showcase for a Belgian strength, nutrition, and mental performance coach — engineered to flip from a non-commercial connection card to a WER-compliant Eenmanszaak through config, not a second branch.

062026Built — internal infrastructure & unreleased

MacroTrack

Sole developer — schema, Edge Functions, app, iOS submission

An AI meal tracker built around one idea — you should be able to say what you ate and be done. Speech or free text, no search box, no portion guessing.

Architecture diagram: Claude Code hands a task to the local-agent-mcp server, which runs an Ollama model on your own machine behind three guardrails — path resolution, a three-turn cap, and a command allowlist.
072026Built — internal infrastructure & unreleased

local-agent-mcp

Sole author — design, implementation, tests

An MCP server that lets Claude Code hand work to a model on your own machine — and a sandbox tight enough that letting it is reasonable.

  • MCP
  • Ollama
