Summary
🤩
Rockstar🎓
Top SchoolFranklin D is a Head of Engineering based in Paris with 12 years of experience bridging academic research and production software across cryptography, genomics, HPC and ML. He holds a PhD in Computer Science and an engineering degree in Applied Mathematics, and has transitioned from postdoctoral work in bioinformatics to senior engineering roles building EVM-compatible systems and developer tools. At ConsenSys he contributed to Linea zkRollup work and on GitHub he enhanced Hyperledger Besu’s EVM tracing and debugging, showing a knack for improving observability in complex blockchain clients. He combines hands-on backend and systems engineering with research-grade rigor—applying deep learning to genetics, designing large-scale data pipelines, and leading engineering teams to productionize experimental tech. Notably, he moves fluidly between low-level JVM internals and high-performance genomic computation, making him effective at tackling both crypto and scientific computing challenges.
