Media Buying
Your ads, placed where your customers actually look. I manage campaigns across Google, Meta, and display networks — turning ad spend into measurable revenue, not just impressions.
I'm Chris de Gruijter, a Data-Driven Digital Marketing Specialist
I turn data into decisions and campaigns into revenue. With 22 years in digital marketing — from managing MYR 150K+ monthly ad budgets for insurance giants to raising MYR 7 million for social causes — I've learned that great marketing lives at the intersection of analytical rigor and creative instinct. I build strategies grounded in real numbers, not hunches.

Conversion Optimization
More conversions from the traffic you already have. I analyze your funnel, test what works, and fix what doesn't — because driving traffic to a leaky bucket is just expensive water play.

Lead Generation
Qualified leads that actually pick up the phone. Using AI-powered targeting and proven nurture sequences, I build pipelines that fill your CRM with prospects ready to buy — not just browse.
4
Business Development
New markets, strategic partnerships, and revenue channels you haven't tapped yet. I help you identify growth opportunities and build the relationships that turn them into real business.
5
Data Analytics
Dashboards that tell you what to do, not just what happened. I turn your raw data into clear, actionable insights — so every marketing decision is backed by evidence, not guesswork.

Development & Scripting
Custom tools that save hours, not create headaches. From marketing automation scripts to full web applications, I build solutions that make your processes faster and your team more productive.
How I Configured Claude Code: Agents, Hooks, Skills, and a 4-Layer Config System
Claude Code is one of those tools that's useful out of the box, but becomes genuinely powerful once you invest a couple of hours in configuration. The defaults are fine. A well-designed config system that persists across every project, loads automatically, and keeps Claude informed about your standards, agents, and workflows — that's something different. I spent time building exactly that: a 4-layer configuration system that spans global rules, workspace-level context, agency-level context, and per-project detail. It's version-controlled, symlinked so changes propagate everywhere instantly, and includes 29 specialist sub-agents, a hooks system that auto-formats and checks code after every edit, slash command skills, and persistent memory across sessions. This post documents how the whole thing works.

How I Built a Bulletproof Vibe-Coding Environment on Linux
Vibe-coding with AI is genuinely useful. Claude, Gemini, Copilot — these tools write real code, fast. But they also introduce a threat surface that most developers aren't thinking about. The AI can suggest a package name that doesn't exist and a malicious lookalike gets installed instead (slopsquatting). An IDE extension with broad file access can read your <code>.env</code> files and exfiltrate API keys. A compromised npm install script can do damage before you've even looked at the code. I spent a few days building an environment that lets me vibe-code freely without any of those risks. This post documents exactly how it works, what it protects against, and how I use it day-to-day.
