Rassel builds careful software.

I'm Rassel, a Computer Science student at the University of Liverpool — cybersecurity specialism, Year in Industry. I build tools that stay honest under load.

Four shipped projects, one lab. Recent work spans personal finance, cycling analytics and password security — React and Next.js at the front, Node, Prisma and Python behind, kept truthful by end-to-end tests.

I design the system, build it with Claude Code, then attack the result with black-box testing. I care about software that explains itself: clear data, legible interfaces, and measurements you can check rather than take on faith.
