Driving Innovation and Growth
for Tech Ventures
Fractional CTO
I help startups and scale-ups turn ambitious software ideas into scalable businesses. Whether it’s building an MVP, managing engineering teams, or integrating artificial intelligence, I provide expert guidance to avoid costly mistakes and accelerate growth.
Many tech founders struggle with costly mistakes, overspending on development, accumulating technical debt, and misalignment between business and engineering. Without the right expertise, they risk building software that doesn’t scale, hiring the wrong people, or making decisions that become expensive to fix later.
With two decades in software engineering and one as a CTO, I’ve built, scaled, and led technology teams. I specialize in SaaS and artificial intelligence, helping startups navigate technical and strategic challenges. I have founded and scaled multiple startups, including one successful exit. I know how difficult it is to balance fast execution with long-term scalability, and how poor technical decisions can hold back an otherwise great ventures.
Unlike traditional consultants who mostly produce abstract strategy papers, I pass on real-world experience gained from building and growing companies myself and hands-on building software for many years. I help founders avoid common pitfalls, so they can focus on scaling their business instead of fixing preventable problems.

Why Work With Me?
As an entrepreneur, your most valuable resource is often time. There is enough venture capital on the market, employees can be hired and know-how can be acquired. But no one can give you back the time you lose when making the wrong decisions. A bad piece of software architecture, vacant key positions or an unrealistic strategy can set you back years and put the success of your venture at risk. Large corporations work with consulting firms, but startups and scale-ups are often left to their own devices. My service consults with SMEs, helping them to maintain their laser focus and build a sustainable competitive advantage.
