Lukas Möller

Research Engineer @Anysphere, building Cursor

I develop high-performance, scalable, and maintainable software - mostly using JS/TS, Rust, Python, Go, and C++. I have a passion for compiler design, distributed systems, information retrieval, and building products that are delightful to use.

Publications

• Cppless: Productive and Performant Serverless Programming in C++. Proposes and implements a single-source programming model for C++ on top of Clang.

Projects

• wok is a toy compiler from a Swift-like syntax to WASM using a custom SSA IR.
• community-solutions allows ETH students to collect & discuss solutions for old exams. It powers baugis.ethz.ch, exams.vis.ethz.ch, exams.vebis.ch, and exams.vcs.ethz.ch
• pdf-viewport is a thin wrapper around pdf.js to display PDFs in React.
• class-parser implements a rudimentary parser and visualizer for .class files produced by Java compilers.
• I also wrote a neon-optimized Rust implementation of BERT, an epoll-based key-value store, a high-performance native hex editor, a library that wraps gRPC-web in RTK Query, a polyglot (CPU / WebGL) raytracer and a couple of other things.
