Challenge

Enterprise digital work was split across a mature commerce footprint, a separate rewards experience, and forward-looking civic-innovation questions. Each thread had different vendors, timelines, and stakeholders — without a shared technical narrative tying day-to-day delivery to longer-term bets.

Approach

  1. Extended and hardened the .NET e‑commerce layer so merchandising, checkout, and back-office operations could evolve without constant firefighting.

  2. Stood up accelerator-style structures and delivery rhythms so new concepts could be tested with realistic technical constraints instead of one-off prototypes.

  3. Advised on Japan Smart Cities–aligned initiatives where policy, data, and partner ecosystems intersect — translating ambition into implementable scopes.

  4. Shipped native iOS and Android applications for the rewards program so members had a consistent, store-quality experience next to the web stack.
