Summary
🤩
RockstarAndrei Stoian is a research scientist and ML engineer based in Paris with four years of experience specializing in privacy-preserving machine learning. At Zama he contributes to Concrete ML, enhancing FHE-compatible workflows by restoring benchmarks, advancing quantization-aware training for CNNs, and improving Brevitas integration and padding support. He blends hands-on engineering with applied research, shipping practical features that make encrypted inference more usable for real-world models. Notably, his work focuses on reconciling modern ML tooling with the constraints of fully homomorphic encryption, a niche that requires both systems thinking and deep model-level adjustments.
