Selected Work

A small selection of products I helped build across Japan and Indonesia. My role has moved between product delivery, platform work, and the unglamorous performance problems that matter when people use the thing. The résumé has the fuller timeline.

A few things I built

  1. Living Japan apartment-search landing page

    2020–2022 · Technical lead · Inbound Platform

    Living Japan

    Architected and led a four-person team building a foreigner-friendly apartment platform; page caching, bundle work, and image compression helped bring loads below 100ms.

  2. MAPICON fire-safety inspection app landing page

    2021–2022 · Contract software engineer · OMY

    MAPICON

    Built a guided fire-safety inspection app and automated multi-page PDF reporting, reducing manual work by up to 80%.

  3. RV Japan vehicle-rental platform landing page

    2020–2022 · Software engineer and team lead · Inbound Platform

    RV Japan

    Led a two-person team in decoupling and redesigning the legacy frontend for a nationwide vehicle-rental platform.

  4. Tabiko travel concierge app landing page

    2018–2020 · Lead app developer · Fast Japan

    Tabiko

    Led the next version end-to-end—concierge chat app and web back office—raising engagement by 20% and cutting response time by more than 80%.

  5. Truck-sharing platform landing page

    2022 · Contract software engineer · Kimura Shoken

    Truck Sharing

    Redesigned key pages for a truck-sharing platform, reducing bounce rate by 24% and increasing organic average session duration fivefold.

    Original site is no longer live.

Earlier work

Older experiments, apps, and client projects. Some are obsolete, replaced, or simply from a much earlier version of me.
