Cryptography Engineer

Aztec Network

Hi, I’m Adrian.

I’m a cryptography engineer with experience in zero-knowledge proof systems, threshold signature schemes, and secure multi-party computation. At the moment, I’m working for Aztec on PlonK-ish proof systems, where I fight with polynomials to improve zkSNARK performance. I graduated from EPFL in 2022 where I obtained a bachelor’s degree in mathematics and a master’s degree in computer science. Previously, I worked part-time alongside my studies, for Taurus as a research intern, with a strong focus on threshold signature schemes.


Cryptography Engineer
March 2022 – Present Remote
Discover and implement new zkSNARK protocols.
Cryptography Intern
September 2021 – March 2022 Remote
In the context of my master’s project, I am working on the Plonk zero-knowledge proof system and researching new techniques to improve prover efficiency.
Research Intern
September 2020 – September 2021 Lausanne, Switzerland
Alongside my studies, I have been researching various aspects of threshold signature schemes in the context of cryptocurrency custody, under the supervision of Jean-Philippe Aumasson. In particular, we co-wrote a survey with Omer Schlomovits (ZenGo) about different dishonest majority threshold ECDSA schemes. In addition, I developed open-source implementations for the FROST and CGGMP21 protocols in Go, and participated in several audits of threshold signature libraries.
Software Development Intern
July 2018 – August 2018 Lausanne, Switzerland
Over the course of one month, I developed a C library for analyzing heart-rate signals. This extended an existing code base, and taught me how to navigate larger software project.
