Turning the Idea Into Reality

The biggest challenge was fragmentation. Every battery manufacturer exposed different APIs, authentication systems, telemetry structures, and control parameters. To solve this, we initiated meetings with battery manufacturers, studied their API ecosystems, and mapped operational differences between vendors. Simultaneously, we analysed AEMO market data behaviour and emerging VPP business models to understand how energy arbitrage and battery orchestration could create customer value.

I contributed to:

Product strategy and VPP feature planning

• Competitor analysis and future-market positioning

• User flow design and platform architecture thinking

• UX wireframing and dashboard experiences

• Frontend implementation and component systems

• Designing battery onboarding journeys

• Structuring scheduling and automation experiences

• Working alongside backend developers to define unified API wrappers

We created a middleware wrapper architecture that normalised multiple battery APIs into one standard internal system. This allowed the platform to support scheduling, price-based charging/discharging, remote orchestration, and future scalability without redesigning the frontend experience for every vendor.

The entire platform was designed and launched under extreme time pressure while the Australian energy market was rapidly changing. The speed of execution became one of the project’s defining achievements.

Conclusion

GEE Sync transformed GEE Energy from a traditional electricity retailer into a future-focused VPP technology player. Beyond building software, the project demonstrated how rapid research, strategic UX thinking, and collaborative execution can turn an emerging market opportunity into a scalable energy platform within just two months.
