Freelance Developer & Creative Technologist, stefancg

As a Netherlands-based Freelance Developer & Creative Technologist, I do not simply write code; I architect digital products that solve complex business problems.

In a digital ecosystem saturated with templates and generic solutions, true differentiation requires a convergence of disciplines. I bridge the gap between the rigorous logic of software engineering and the emotive power of high-fidelity visual art.

Whether optimizing render pipelines for the Flutter Impeller Engine to ensure 60fps performance  or designing Retrieval-Augmented Generation (RAG) systems that turn raw data into actionable business intelligence , my work is defined by precision, scalability, and impact.

The StefanCG Promise:

  • Performance First: Leveraging the latest rendering technologies for zero-latency interactions.

  • Visual Fidelity: Studio-grade 3D visualization using Unreal Engine 5.

  • Strategic Insight: CTO-level perspective on product lifecycle and scalability.
