Karl Mueller

Senior Software Developer

Years of experience building out high-throughput backend systems for such tasks as delivering bulk email or searching and data-mining large CRMs. Also deep frontend experience in React, Angular and vanilla Javascript. I have a knack for quickly grokking complex undocumented or otherwise orphaned or abandoned systems and then adding desired features and correcting bugs.
