Portfolio analysis — 27 projects, 45 days, one architecture.
A full review of the codebases reveals no "vibe coding", but governed software architecture — delivered at a speed and with a level of control that is evident from the commit history itself.
Twenty-seven live projects across domains that rarely come together under one roof: holiday rentals (StayYouSoon, Dolce Dutch Dream), hospitality tools (De Hoogmolen Hub, House Guide Hub, Honesty Bar, Breakfast Hoogmolen, Home Harmony Hub, Harmony Homes Waste), AI-driven revenue management (Guesty Analytics with 17 predictive KPIs, YUKI Guesty Metrics, Intelligent Guesty Hub), e-commerce (Sip & Save, Nostro Sapore, Fresh Dish Revamp), dynamic pricing and payments (Stripe Real-time Pricing & Availability), analytics & finance (Asset Navigator, CynexBDO Invoices), sport & fitness (HVC Helchteren, HVC Sponsorwerving, Beweegmeer, Move Moment Tracker), operations (Poetslijst, Instructies, Jobs Hoogmolen), lead generation (Bendec, evport) and the meta-platform itself (ITSolutions, Hoogmolen platform, Performance/SEO audit tool).
What the numbers actually mean.
The metrics behind the speed, not speed as a standalone claim.
~10K lines of code per day
Averaged over 45 days without a break — 453,000 lines of own code, measured from actual commits, not generated boilerplate.
Depth per project
501 edits on StayYouSoon, 145 edits on Asset Navigator, 23 edits in a single day on Honesty Bar. No throwaway demos — iteration to production quality.
Governance at v9.55
A proprietary governance system with a changelog and internal process documentation that keeps AI changes within the architectural lines. Version 9.55 is genuine iteration, not a marketing number.
Enterprise-grade backend
Role-based RLS policies, edge functions in production, Guesty integration down to commission level — the kind of backend work that normally takes a team of three.
1000+ multilingual SEO pages
Runtime translator, Schema.org pipeline and PageSpeed monitoring in production. SEO surface at enterprise scale, live and indexable.
Triple review process
Every change goes through three review rounds before a single line of code exists. Quality is a process, not a coincidence.
Governed architecture — not vibe coding.
The core conclusion from the review of the 27 codebases.
AI coding is often dismissed as vibe coding. That label fundamentally undersells these projects. What's here is governed software architecture: a platform at v9.55 with ~453,000 lines of own code, a self-authored governance system that keeps the AI within the lines, a triple review process before every line of code, and backend work (RLS, edge functions, Guesty integration down to commission level) at a professional standard.
Based on a full scan of 27 codebases.
The seven projects that carry the portfolio.
Each project reviewed based on actual commits and source code — not what the app promises, but what's underneath.

In control of the stack itself
Not a single component is pulled blindly from a template. RLS policies, edge functions, database schemas, deploy pipeline — everything deliberately chosen and self-designed.
Triple review process
Every change goes through three review rounds before a single line of code exists. Governance documentation keeps the AI within the architectural lines.
Domain-owner mindset
Not isolated experiments, but one coherent platform for its own business domain — from booking engine to financial reporting.
