I build digital products and invest in things that make economic sense.

iOS developer and entrepreneur focused on scalable systems, monetization, and long-term value.

What I Do

What problems do I solve repeatedly?

Digital Product Development

  • performance at scale
  • modular, long-lived architecture
  • monetization and retention by design
  • systems that don’t collapse under growth

AI-Driven Process & Product Optimization

  • automation of decision-making and workflows
  • product-level AI integration with real user value
  • systems designed to scale without constant supervision

Business & Investing

  • Active investor in stocks and real estate
  • Decisions based on data and downside control
  • Preference for systems that work without daily attention

PROJECTS

Selected work demonstrating scale, technical depth, and business impact.

“Systems scale, motivation doesn’t.”

Return over visibility

I optimize for economic return and efficiency, not for vanity metrics or visibility that doesn't convert to value.

Monetization as a constraint

Business models should be designed into the product from day one, not added as an afterthought.

Growth exposes architecture

Weak systems collapse under pressure. I build architectures designed to handle success without breaking.

Simplicity survives

Complex products are fragile. Simple, focused tools tend to outlast trend-chasing feature bloat.

"Věřím v sílu eliminace zbytečného a zaměření na to podstatné. Skutečná hodnota vzniká tam, kde se protíná technická excellence s ekonomickou realitou."
