Rockstar🎓
Top SchoolDavid Palm is a seasoned Senior Software Engineer with 17 years of experience building and leading backend systems, currently based in Stockholm. He has deep expertise in Rust and distributed/blockchain infrastructure, contributing to high-profile open-source projects such as Substrate, libp2p, jsonrpsee and the tracing crate where he improved core macros, performance benchmarks and test coverage. His career blends hands-on low-level systems work—macro design, trie and WASM executor changes, and threshold cryptography—with leadership roles including Head of Engineering at Parity and Toposware. He co-founded a SaaS startup and has a track record of improving reliability through rigorous testing and refactoring across languages (Rust, Go, Ruby). Comfortable navigating both research-grade cryptography and production networking stacks, he also brings a physics background that informs his disciplined approach to complex algorithmic problems. Colleagues would note his knack for quietly fixing subtle macro and serialization bugs that materially improve long-term maintainability.
