Front-end engineering for teams that ship experiments.

Hello! I’m Pascal, a front-end developer and CRO specialist from Enschede. I’m the guy you need to make your website interact, perform, and convert better — through precise experimentation and performance engineering that actually moves the needle.

It’s my pride and passion.

What I do

I specialise in high-velocity experimentation platforms — GrowthBook (the foundation of the Mintminds Toolbox), Optimizely, Convert, and Cloudflare’s edge stack. Building testing architectures that scale isn’t just about handling traffic — it’s about making the next ten experiments cheaper than the last. Frameworks where behavioural insight and technical performance work together to drive genuine conversion improvements.

Where I spend my time

A/B Testing at Scale

33 live items across 6 Mintminds client brands, all running through the in-house GrowthBook Toolbox — live Chrome-extension preview, automated scaffolding, CI-grade dependency auditing.

Front-End Performance

Conversion is a performance discipline. Mutation observers that beat FOUC, intersection observers for honest viewport tracking, critical-path JS shaved until experiments stop hurting Core Web Vitals.

Tooling That Compounds

Twenty-three years of writing the unglamorous helpers that make the next ten experiments cheaper than the last: globals detection, smarter logging, bulletproof DOM injection, dependency guardians.

Tools I've built

All tools

In-house dev tooling that makes the work cheaper and faster. Some live inside the Mintminds GrowthBook Toolbox; some are stand-alone helpers.

GrowthBook Toolbox

Multi-client experimentation platform — 6 active clients, 33 live items, semantic-architecture v2.8 with QA tooling, Jira scaffolding, and CI-grade dependency auditing.

Read the deep-dive

Dev Panel

Inside the Toolbox. Force Variation banner, runtime profiler with DOM before/after snapshots, dark/light tracer, four debug modes from quiet to verbose.

Covered in the Toolbox deep-dive

RequestLite

Manifest V3 Chrome extension. Redirects production script URLs to localhost; live-reloads tabs over WebSocket. Production-data dev with seconds-not-minutes feedback.

Dep Guardian

Weekly npm audit. Patches auto-applied; minor releases reviewed by an LLM against release notes; majors always prompt. Zero extra API cost — reuses the existing CLI session.
