About

Engineer, manager, founder

I've spent two decades on both sides of engineering - leading teams and organizations, and writing the code myself - in startups finding their footing and in global enterprises operating at scale.

I have a strong background in AI and web applications, and a particular love for good UX.

I'm an entrepreneur at heart, and I know how to find a way through to the result.

Leadership at every scale

Engineering manager at Imperva and CA Technologies, VP R&D at Proonto, tech lead at AOL. I've built and led teams in young startups and in global enterprises.

Entrepreneurship, end to end

Founded algotext.io (acquired by Costapp) and co-founded mashlom.me. Owned the whole path: product, engineering, marketing, go-to-market and product–market fit.

AI, cloud and security

Hands-on depth in machine learning and AI, cloud infrastructure at Google Cloud, and cyber security - including published research on anomaly detection for cloud systems.

Healthcare and public impact

Built mashlom.me with a team of volunteers to give medical teams practical, everyday tools - with dedicated apps developed for five hospitals.

Experience

Where I've built and led

Two decades across management and hands-on engineering - in startups, scale-ups and global enterprises.
