Idea on Monday. Live next month.

A restaurant tracked hours on a slow Android app — the round time picker, painful mid-service; card tips split by hand; salaries estimated by gut feel.

Big-button clock-in, front-of-house tip distribution to the cent (largest remainder), closures draft→validated→paid→locked. Then a multi-vertical HR suite: 8 industries, a French labour-law engine (paid leave, overtime, compliance alerts), graphical dashboards, scheduled payroll email (Cron). Multi-tenant, per-establishment private scope. Cloudflare Workers + D1 + Drizzle + R2 + Hono, React 19.

Live at clock.mindvisionstudio.com — in production, 8 business verticals, French labour-law engine, 1,405 passing tests. Cloudflare edge, GDPR (former-employee anonymization).

Couples discover each other's real preferences slowly — over years, or after conflicts. No intentional space to accelerate mutual knowledge before those situations arise.

Real-time quiz engine (WebSocket state machine + offline sync), 17 Docker services, React 18 + Capacitor monorepo (iOS/Android/Web, 95% shared code), Stripe, OpenAI insights. 117K lines TS, 98 DB tables, 376 endpoints.

Live at halvyn.app — gamified couple experience across 9 languages and 3 platforms, edge-delivered via Cloudflare Workers.

Weekend city trips are affordable — but guides dump 400 POIs with no logic. No itinerary that respects geography and must-sees without zigzagging across the city all day.

Static-first platform on Cloudflare edge — 2,997 curated itineraries (999 × 3 locales EN/FR/ES), ~17,900 geolocated stops, AI semantic search (Workers AI + Vectorize), 3D WebGL globe, zero-JS by default for SEO. 257KB total bundle.

Live at shortstayguide.com — 333 cities (incl. 22 French: Paris, Lyon, Marseille, Nice, Toulouse, Bordeaux, Nantes, Strasbourg, Cannes, Aix, Avignon, Reims, Lille, Montpellier, Annecy, Chamonix, Saint-Malo, Rennes, La Rochelle, Biarritz, Carcassonne, Colmar), 5 continents, full EN/FR/ES trilingual parity, real-time weather, GDPR-compliant monetization.

Apple Magic Keyboard on Windows — layout doesn't match, modifiers reversed. Free solutions exist but are buried and incomplete. Paid tools (€20–30/yr) add FN + Touch ID remap via custom firmware — overkill just to get a working layout.

Dual distribution channel. (1) Native Tauri/Rust app (NSIS/MSI x64) that compiles keyboard DLLs at build time, installs them to System32, remaps modifiers via registry, with post-install Health Check + Bluetooth Pairing Assistant + F12 remap. (2) Public Svelte 5 site on Cloudflare Workers — interactive preview + 12 downloadable ZIPs (6 layouts × 2 archs cross-compile) on R2. Monorepo workspaces with shared `KeyboardVisual` component across desktop and web. EN/FR i18n on both.

V0.4.0 production — free, open-source. 6 layouts × 2 archs = 12 DLLs, 78 tests, 0 TS errors, 0 clippy warnings. Site live on magicwindows.mindvisionstudio.com, downloads on dl.mindvisionstudio.com (R2). 140 commits, 12,663 source LOC.

Anthropic shipped Claude Buddy in April 2026 — a terminal tamagotchi natively integrated in Claude Code. It generates a deterministic creature per user but ships no leveling, progression, or evolution. The community asks for it on GitHub; no one delivers.

Local-first RPG progression layer wrapping Buddy: 5 official Claude Code hooks mutate a file-locked JSON state (atomic + Windows EPERM retry) that derives XP / 6 phases / 46 medal achievements. 19 original ASCII species generated deterministically from seed, or shows Buddy if detected. Custom OTel collector + mobile PWA web view. Zero telemetry, trademark-clean.

Shipped on npm as @mindvisionstudio/petforge — launched in 2 days (9 releases), iterated to v3.7.8 / 124 commits. 500+ tests passing, 0 TS errors, ~10.6K TS lines, ~216 KB bundle. Apache 2.0 on GitHub.

Existing digital business cards are either heavy (CRM/scanner/teams apps like Azzapp) or ugly (basic generators with flat templates). None deliver the "premium" rendering that truly feels like its owner — 3D flip, parallax, holo, real visual identity. And none offer a lightweight mini-site for proximity businesses (restaurants, beauty, retail) who just want to share menu/hours/reservation via QR without installing a full app.

Personal V1 MVP as MindVision Card → pivot to multi-user SaaS in Phase 2-4 → rebrand to Bizleen + Business tier in Phase 5. Lucia v3-style custom auth (argon2id + AUTH_PEPPER), Cloudflare D1 + R2 + Workers Standard ($5/mo), Resend emails, Stripe 3 tiers (Free / Pro €9/yr / Business €19/yr) with founder pricing. 60+ SSR routes, 33 migrations, 11 components. Canonical CardPreview with container queries (cqi) for identical thumbnail 240px and fullscreen 440px rendering. 8 themes + 20 Vecteezy Pro boomerang-encoded video backgrounds. Business mini-site: photos, menus, hours, reservation link, analytics. France GDPR-grade by design.

Live on bizleen.com — anyone creates their card in 3 minutes, free, GDPR-compliant. Pro unlocks logo without branding, Business unlocks the full mini-site. 14 simultaneous cards on the landing with zero GPU flicker (non-obvious backdrop-filter vs video decoding diagnosis). Debounced live handle availability + suggestions, anti-enumeration forgot password, GDPR JSON exports, cascade account deletion, Stripe customer portal for subscription management.

An IS-governance audit is 76,000 words of analysis, 64 scored risks and 4 costed target architectures — usually locked in a PDF nobody opens. The Liora Cyber Admin project deserved better than a dead dossier.

The DATASC.SEA dossier delivered as a product: AMDEC risk explorer (sort / filter / severity), a global selector that switches 4 costed target architectures (CAPEX / OPEX / 5-yr TCO), 29 dual-reading blueprints, static ⌘K search (Pagefind), Mermaid diagrams. Server-side PIN lock (HMAC-SHA256 cookie, KV anti-brute-force), zero runtime dependency. Static Astro + Cloudflare.

Live at gouvernance.mindvisionstudio.com (PIN-protected) — a consulting audit turned into an interactive, secured command center. Reusable "audit-as-a-site" template: one dedicated space per engagement.
