What I'm looking for

I am looking for a role that fosters innovation and allows me to lead technical teams while driving product development in a dynamic environment.

I am a full-stack engineer and technical founder with over 20 years of experience in fintech, mobile apps, cloud computing, and crypto/Web3. I have successfully built products and services from the ground up, creating viable businesses that scaled to acquisitions, such as Payvision, which was sold for $200 million. My expertise lies in developing minimum viable products, achieving product-market fit, and driving growth to millions of users, subscriptions, and transactions.

As a co-founder and CTO of multiple startups, I have led technical strategies and engaged with suppliers, customers, investors, and boards. My entrepreneurial drive has enabled me to transform ideas into successful ventures, raising over $500K and building multimillion-dollar companies. I consistently leverage AI tools to enhance productivity and deliver end-to-end solutions, from mobile apps to cloud infrastructure.
