Graham Lea is a senior software engineer and technology leader with 21 years' experience building mission-critical systems across telecommunications, finance and energy. He blends hands-on Java/Kotlin backend engineering, distributed systems and database design with proven leadership—from leading multi-team engineering organisations at Tyro to founding Archium, a SaaS product that models microservice architectures using graph databases. Recently he’s focused on clean-energy software, shaping Amber’s EV-charging optimisation product that coordinates solar, batteries and pricing to turn charging into a savings (or income) opportunity. Equally comfortable shipping code, architecting event-driven systems and coaching teams, he pairs a pragmatic, customer-focused product mindset with deep technical troubleshooting and refactoring skills. Notably, his entrepreneurial work at Archium reveals an aptitude for surfacing hidden operational knowledge in complex microservice landscapes.
