Four years of production systems and new programs

Idemitsu Kosan, a Fortune Global 500 energy company, kept bringing Craft & Logic back from 2019 through 2022 — not for a single build, but across commerce, a customer rewards product, an internal accelerator, and smart-cities advisory.

Challenge

The work was not one program. A mature commerce operation, a separate rewards experience, an innovation portfolio, and civic-technology questions each had different users, vendors, and timelines. The hard part was staying rigorous inside each of them without losing the thread of a single relationship.

Approach

  1. Treated each initiative as its own shape — commerce operations, a rewards product, an accelerator, advisory — and kept technical standards consistent across them.

  2. Extended the .NET commerce stack so merchandising, checkout, and back office could change inside enterprise constraints instead of as a one-off rewrite.

  3. Set delivery rhythms for the accelerator so new concepts were tested against real constraints, and translated smart-cities ambition into scopes that could actually be implemented.

  4. Shipped native iOS and Android apps for the rewards program so members had a production experience beside the web commerce stack.

Outcome

The relationship demonstrates repeated trust across different kinds of work: production commerce and a customer product in market, plus innovation and advisory that moved from exploration toward systems the organization could deploy. Idemitsu could point to both.
