Christiaan Roos - Systems architect and co-founder
Christiaan Roos
Systems architect, financial econometrician and co-founder of Goldflux.
Christiaan designs data, risk and AI systems for organisations where decisions need to remain explainable, testable and workable in practice.
Professional focus
Systems where calculation, decisions and control meet
For more than fifteen years, Christiaan has worked where quantitative models, technology and operational delivery come together. His experience spans banking, insurance and other regulated environments.
Architecture and integration He designs systems that connect data, calculation logic and workflows without hiding the assumptions that make them work.
Risk and financial models His work includes IFRS 17, IFRS 9, Solvency II and Basel III, as well as model validation, reporting and scenario-based analysis.
Data, AI and automation He applies AI where it improves analysis, documentation or repeatable work, with clear inputs, validation and human oversight.
Delivery across disciplines Christiaan works between policy, actuarial teams, IT and business stakeholders to turn complex requirements into implementable systems.
How he works
Technology is useful only if people can understand and operate it
- Make decisions traceable
- Inputs, assumptions and transformations need to be visible enough to review when a result is questioned.
- Validate before scaling
- A contained implementation with automated checks provides a stronger foundation than broad automation without evidence.
- Translate across disciplines
- Technical design must remain meaningful to the people accountable for policy, models, operations and delivery.
- Keep scope honest
- Clear boundaries, ownership and fallback behaviour make a system easier to improve without creating hidden risk.
Selected experience
From quantitative models to integrated systems
Experience across financial reporting, risk, data and delivery in regulated environments.
At Goldflux
Turn complex questions into manageable systems
At Goldflux, Christiaan brings this background into work on strategy, systems and ventures around technology, decision-making and long-term value.
Start with the underlying decision The first question is usually not which tool to use, but which decision, process or source of uncertainty needs to become clearer.
Build on what already works A useful system connects to real data, existing workflows and the people responsible for the outcome.
Design for controlled implementation The Goldflux approach combines a practical pilot with explicit criteria for quality, control and ownership.
Keep the long term in view Systems need to remain maintainable as teams, regulations and priorities change. That is why implementation starts with structure rather than scale.
