Summary
👤
Senior🎓
Top SchoolWilliam Afonso is a backend-focused senior software engineer based in Paris with five years of experience building robust systems for e-mobility and smart-grid domains. He has moved from research roles at EDF—where he contributed to standards work, authored an international patent, and developed embedded and simulation tools—to product-focused backend engineering at Switch and now Believ, blending deep domain knowledge of EV protocols with pragmatic architecture and DevOps practices. Comfortable with both hardware-adjacent embedded work and cloud-native backend stacks, he frames architecture decisions with benchmarks, standards and economic trade-offs. He holds advanced engineering credentials from CentraleSupélec and ESIEE Paris and has a track record of turning complex technical standards into production-ready services. An engineer who bridges research, standardization committees, and shipping product, he brings uncommon fluency in EV communications (ISO 15118, OCPP, etc.) to backend system design.
