Experience

Full-time engineering work and side projects I build in my free time. For earlier internship experience, see Internships.

Full-time

Led end-to-end quality design for traffic gateway anti-crawler systems, frontend security frameworks, and circuit breaker / degradation platforms.
Defined validation strategies for 50B+ daily and 200B+ peak request scenarios, including abnormal traffic and multi-region data isolation coverage.
Built an API + Web UI automation framework that increased core regression coverage from 65% to 95% and reduced release regression effort by 60%.
Established requirement audit and release control loops that protected 120+ core initiatives with 12 consecutive months of zero P0/P1 production incidents.
