# Digital programs for Idemitsu Kosan

Four years of work with a Fortune Global 500 energy company: a .NET-based commerce stack, an internal accelerator, consultation on Japan’s smart-cities agenda, and native iOS and Android apps for a customer rewards program.

**Client**: Idemitsu Kosan  
**Year**: 2019 — 2022  
**Engagement**: Platform · Applications · Advisory  
**Team**: Architects, senior engineers, and program leads across commerce, mobile, and innovation

### 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.
