PROFILE

Fielding Johnston

Fielding contributed to the nesaorg/nesa repository by developing and documenting features centered on Equivariant Encryption (EE) for privacy-preserving machine learning. Over three months, Fielding built a demo integrating DistilBERT for encrypted sentiment analysis, enabling client-side tokenization and decryption with server-side inference on encrypted data. The technical approach leveraged Python, Hugging Face Transformers, and Git LFS to manage large model artifacts and streamline onboarding. Fielding also implemented real-time LLM inference streaming using Server-Sent Events and enhanced documentation to clarify EE’s computational model and advantages. The work demonstrated depth in backend development, encryption, and technical writing, supporting secure ML workflows.
