About
I'm Marcus, a software engineer based in Singapore with a background in computer science and mathematics. My work spans systems programming, algorithms, and mathematical optimization — I've worked at TikTok, with clients in semiconductors, and now at Squarepoint Capital.
This site is where I write about things I'm learning or building, and host small tools I find useful day-to-day.
