Projects, Papers, and Talks

Here I collect recent projects, papers, and talks. Most projects stem from work in the industry or are part of my PhD. I enjoy specialised, under-explored, and niche areas while keeping an eye on the final product. Nothing gets me more excited than a challenging improvement to low-level infrastructure that results in large impact.

Projects ๐Ÿ“ฆ

Spectrum

Spectrum is a cross-platform, declarative image transcoding library written in C++ with bindings for Android and iOS. The release blog post provides a good introduction. I am one of its original authors.

Argon2Kt

Argon2Kt is an Android/Kotlin binding for the Argon2 password hash algorithm (winner of the PHC). This is a personal project of mine. I have written this blog article which explains more about password hashing on Android.
