Software consultant at QZabre @ ETH building quantum microscope controllers and advancing its in-house QS3 platform with Rust.

Switzerland

Message

At QZabre @ ETH, I drive software for nanoscale microscopes based on quantum magnetometry. I designed and built controllers for photonic and magnetic devices, redesigned the desktop application, and championed Rust across the in-house QS3 platform.

At Casper Association, I led an 11-person R&D team and applied zero-knowledge cryptography to deliver a ZK rollup sustaining 4,000 transactions per second and a ZK light client. Across climate research, cryptography, blockchain, and software consulting, I’ve helped turn research and complex requirements into working systems.
