CONTEXT
EnergyOne, an Australian publicly traded ETRM, expanded into the European market by acquiring smaller trading platforms across Europe (eZ-energy, EGSSIS) and the UK (Contigo, GMSL).
The Problem: Each deal added its own interface. enTrader, the core platform, hadn’t been rebuilt in two decades.
The impact: Onboarding a new account took weeks. Support tickets kept growing. Churn was rising, and most clients used the API instead of the UI just to avoid it.
The Mandate: The CTO brought me in directly to lead the product architecture behind the unification.
SYSTEM

Research: 14 interviews — clients and internal stakeholders — plus 3 working sessions to map friction points. Fed into a single navigation architecture, validated with product and engineering.

The architecture call: Engineering ruled out a full platform rebuild. I proposed microfrontends per platform on one shared Design System, connected through Tailwind — each platform integrates on its own timeline instead of being rebuilt from scratch.

AI pilot with BASF: In parallel, I helped lead the squad building a custom version for BASF, testing AI-assisted development (Claude Code, Windsurf) against a team working the traditional way. Six months total, two-week sprints.

IMPACT

Delivered: Full Design System and the three most complex enTrader screens, architected to extend into a multi-platform shell once EZ-energy and Eggsport come online.

Engineering velocity: The AI-assisted team ran 20% faster than the control team building the pages, navigation, and the Storybook implementation of the Design System.

At handoff: Design System and BASF build validated and handed to engineering, in staging. Production rollout and its OpEx impact land after that point — outside my window on the project.
