A Waterloo mechatronics alumnus who entered top of his class, he combines systems-level thinking with pragmatic DevOps and observability expertise (notably contributing to Kafka cluster monitoring and migration from ZkClient to AdminClient). Andrew has a strong track record in fintech and crypto infrastructure, rapid prototyping of indexers and blockchain token services, and reducing batch runtimes by orders of magnitude. He mentors engineers while keeping a coder’s attention to API quality, testing, and maintainability. Colleagues describe him as a technical generalist who prefers solving hard infrastructure problems and surfacing actionable metrics.
