Qi Logan Liu

CS Master's Graduate · Full-Stack Developer · AWS Certified

Master's in Computer Science from Victoria University of Wellington (weighted average ~83%). I've shipped a commercial freelance website for a real business, built a serverless AWS platform with zero downtime, and developed a PostgreSQL query optimizer using Genetic Programming. Before tech, I taught Maths for 8 years — turns out explaining recursion to a hiring manager isn't that different from explaining algebra to a room of 15-year-olds.
