Software developer and founder of Vantura Studios. I turn real business problems into products, internal tools, data systems and AI workflows.
Discuss a projectProduct ownership
From concept and architecture to implementation, launch, iteration and continued technical ownership.
Business + engineering
Commercial workflows, data, product thinking and hands-on software development in one profile.
Selected work
Proof, not a logo wall.
Public products where possible, transparent NDA cases where necessary, and purpose-built demos where the underlying craft matters more than a client name.

Confidential enterprise work
Screenshots, data and implementation details are intentionally not published. The value of the work can still be described without exposing confidential information.
Real business software does not always belong in a public gallery.
I have developed internal reporting, forecasting, calculation and decision-support systems for a major German media company. The projects combine complex business logic, operational data and iterative stakeholder requirements.
Management reporting & dashboards
Forecasting and variance analysis
Custom calculation logic
KPI and benchmark systems
Data integration & transformation
Internal business applications
Stakeholder-driven iteration

How I think about the work
Data → Logic → Decision
The interface is only the final layer. The real work is translating processes, rules and imperfect data into something dependable enough to use every day.

Lab / experiments
The part that can get weird.
Vantura stays clear and business-focused. The portfolio lab is where motion, interaction, prototypes and technical experiments can deliberately go further.

Arsenal
Broad by design.
The useful combination is not one framework. It is being able to move from business problem to data, product, interface, integration and delivery.
