About Theodore

I am a Fractional CTO with 15 years of experience helping startups, corporates, and public organizations turn complex ideas into market-ready products.

My focus is on AI solutions, rapid MVP delivery, and secure data practices balancing innovation with compliance.

I've led projects across healthcare, finance, and the public sector — including cybersecurity initiatives and public-sector digital products — where regulatory compliance, privacy, and reliability were critical. My strength lies in bridging strategy and execution: from defining product architecture to leading cross-functional teams and ensuring solutions are built fast, securely, and at scale.

Typical projects I support include:
  • Designing and delivering AI pilots and MVPs in weeks, not months.
  • Building secure architectures for regulated industries.
  • Leading digital transformation initiatives in startups and enterprises.
  • Providing executive-level guidance and hands-on expertise to public-sector digital services.
Clients choose me when they need more than development — they need a trusted technology partner who delivers executive-level guidance with hands-on expertise to get things built and shipped.

Based between Singapore and Paris, available remotely across Europe and Asia (UK, Benelux).
