Engineering leader who makes AI safe and fast in regulated software.

I have spent my career on one problem: helping software teams ship faster without letting quality slip. AI is the newest tool I have put to work on it, in medical-device engineering where every change has to stand up to an audit.

Each step is a wider scope of work than the one before; the heights show order, not size. The bars count entries in my work record by theme, out of 295, and one entry can carry several themes. Most of the AI work dates from 2025, on top of the quality and delivery work that came first.

Problems I took on

Four problems that crossed teams and business units: what was going wrong, the call I made, and what changed.

  1. Making AI useful where mistakes are not allowed

    AI in regulated software. Philips, 2024 to now.

    Before
    Every requirement in medical-device software has to be traced to its design, tests and risks. That trace was kept by hand across many tools, and gaps surfaced late.
    The call
    Model the trace as a knowledge graph on top of the tools engineers already use. AI suggests links and flags gaps, and a person decides anything regulated.

    “Datta's communication and collaboration style is very positive and always looking for opportunities. It is simply lovely to collaborate with him. His vision is inspiring.”

    Quality Program ManagerPhilips, 2026
  2. Raising the engineering bar across a whole company

    Engineering excellence at scale. Philips, 2020 to now.

    Before
    Nearly every team had continuous integration, but fewer than a third could deploy automatically to a test environment, and about two thirds had no defined process for technical debt.
    The call
    Measure delivery and quality first, then move automated checks into developers' everyday builds and share the data openly with teams.

    “His efforts have led to significant improvements in our DORA metrics for both traditional software and SaaS projects.”

    Rob NicholsonFormer head of worldwide Software Excellence, and my managerPhilips, 2025
  3. Paying down technical debt at scale

    Cost and technical debt. Philips, 2021.

    Before
    Technical debt was adding cost and slowing delivery. One shared application codebase was about 20% duplicated code, so every fix had to be made in several places.
    The call
    Pay the debt down in measured steps inside normal delivery, on a three-year roadmap agreed with the business, instead of stopping for a rewrite.

    ~€2.1M

  4. Growing engineers, not just systems

    Hiring and growing engineers. Amazon, Philips and beyond, 2010 to now.

    Before
    Each part of the organization hired senior engineers its own way. The quality of hires varied, and interview feedback was collected inconsistently.
    The call
    Write the process down, train every interviewer before they join a panel, and bring in bar-raisers from outside the hiring team.

What it was worth

Money, time, quality and adoption, each with my part in it. Where a figure has an entry in the record, it links there.
