Senior Software Engineer at Udemy
Dallas, Texas, United States
Summary
👤
Senior🎓
Top SchoolDonald Lee is a Senior Software Engineer in Dallas with 11 years building scalable Rails and API-driven systems for education technology and large multi-tenant customers. He has repeatedly shipped high-impact features—calendar sync for 1M+ users, appointment and alert systems used across 200+ schools, and mass email/campaign tooling—while driving significant developer productivity gains (e.g., scripts that cut report creation from days to minutes). Donald is equally comfortable eradicating bug backlogs (maintaining zero for quarters) and optimizing production data (safely removing 1M+ plaintext messages), showing a bias for operational excellence. He mentors junior engineers, teaches Rails on Udemy, and experiments with funnels and product marketing as a FunnelHacker, blending engineering rigor with practical growth instincts. Notable but less obvious: he balances deep backend work with creative low-cost infrastructure patterns (timezone CRON strategies) that reduce operational burden.
