Work Experience

I’m a software engineer who likes the awkward bit between “this is broken” and a change that genuinely works. Since 2016 I’ve worked in Tokyo and London, on web, mobile, games and field-service teams, from junior developer to principal engineer. Here’s every job so far, with a sketch of what each one looked like.

Every job so far

  1. – PresentContractRemote

    Centrica

    Principal Software Engineer

    UK energy company. I work on the tools its field engineers rely on every day.

    • Helping decide what to build and what to replace, which means leadership calls, vendor meetings and presenting the options to managers.
    • Hands-on lead of the engineering squad: I take the hardest problems myself, then turn the fix into a pattern the team can follow.
    • Tracked down why complaints about offline syncing kept coming back. There were several separate causes, not one, so we agreed a ranked list of fixes as a team.
    • Broke a large, fragile survey script into small tested pieces and rolled it out in phases, with a single switch to go back.
    • TypeScript
    • React
    • Dynamics 365
    • Power Platform

    • Spent a lot of time in kick-off meetings turning business requirements into features, then followed the developers through the build.
    • Set up the testing approach with Vitest and Playwright, and sat on a few hiring panels.
    • Used Cursor and Claude Code in my day-to-day development, with the company’s blessing.

    • Led a proof-of-concept mobile app that brought several services gas engineers use into one place, behind a single sign-on.

  14. Until

    Before code

    From Naples to Tokyo, the long way round

    Not a straight line, and not planned.

    • Went to a technical high school in Italy with a computer science track. A couple of years later I did a semester of CS at university, and quit.
    • Studied Asian studies at L’Orientale in Naples instead, with an exchange year in Tokyo.
    • In Japan, after a few random jobs, I ended up as a recruiter for a tech company. Some of the developers I talked to had no degree.
    • I hadn’t known that was possible. So I taught myself, and in 2016 got my first developer job.

    • English
    • Japanese
