Experience

NordVPN Linux Client

https://github.com/NordSecurity/nordvpn-linux
A NordVPN application for Linux OS. I acted as one of the project's primary maintainers and am currently a tech lead for the team. One of the toughest challenges it solves is that users may be running it under different environments, configurations, and distributions, and we have to make it work securely everywhere.

UniFFI Bindgen Go

https://github.com/NordSecurity/uniffi-bindgen-go
I worked on fully implementing a Go binding generator for uniffi-rs, which enabled users to generate Go bindings for their Rust library while making life easier for both library maintainers and consumers.

Libtelio

https://github.com/NordSecurity/libtelio
A main library behind NordVPN applications. I was one of its leading designers and one of the initial contributors before it went open source. We did this for the Meshnet feature as we didn't want to break the main VPN functionality and have a new feature work under more restricted environments, such as mobile devices.
