FASCINATION·works — software consulting · est. 2026, shipping since 1999
Hi, I’m Marc Heiligers. Three decades of shipping code across three continents professionally. I build new things, fix old things, scale the things that need scaling, and occasionally perform last rites on the things that should have been put down years ago.
The CV, briefly
01 / Services
01
Whiteboarding system design is, frankly, the fun bit.
I’ve scaled systems, led distributed teams across time zones, built platforms from scratch, and decommissioned a few that had it coming. Whether you need a fractional CTO, an architect-on-loan, or just a senior brain in a production incident — I’ve been there.

Hands on keyboard, all the way down.
Full-stack development, legacy modernization, API design, database optimization. I write code that future developers (including me) can live with — and make the existing codebase a little less hostile on the way through.

03
Skip the demo. Ship the thing.
Agent development, MCP integration, LLM-powered tooling, and a growing collection of building blocks for running language models locally. Things that actually run, overnight, without waking anyone up.

A boutique consultancy with the reach of a much bigger one.
I’m a solo practitioner, but not a solo act. Through a trusted network of partners, I can pull together a team shaped exactly to what your project needs. Designers, developers, accessibility, deep-Ruby, JVM, you name it.
