What I'm hired for

Companies call me when the platform still works but can't keep up, when an acquisition depends on a technical story nobody has verified, or when the board wants AI and the security team is saying no. The common thread is judgment under real constraints — regulatory, commercial, and human.

Ways to work together

  • Technical due diligence for acquirers

    Platform assessment, tech-debt quantification, and integration risk before you close.

  • Fractional / interim CTO

    Senior technical leadership for PE portfolio companies and teams between CTOs.

  • AI adoption and governance for regulated companies

    Identity, isolation, audit, and approval — AI that survives a compliance review.

  • Legacy modernization assessment

    What to keep, rebuild, or retire, and in what order the business can absorb it.

  • AI-generated codebase rescue

    Structure, tests, and boundaries for a codebase a coding agent shipped fast.
