Software Engineer — Finance & Crypto Infrastructure
Hi! I'm Alasdair — a software engineer based in London. I work at the intersection of engineering and finance, building things that need to be fast and correct. Previously on FX eTrading platforms; recently at a leading crypto HFT firm.
Open to interesting problems in high-frequency trading, exchange connectivity, or low-latency infrastructure. Always happy to collaborate with people working on hard problems in the same space.
My entry for the 1BRC: compute min/mean/max temperatures for one billion rows as fast as possible. Uses memory-mapped I/O, chunked parallel parsing across all cores, and SIMD byte scanning to find newlines and semicolons without branching. Ended up in the top results.
