Summary
🎓
Top SchoolXinjie Sun is an experienced advertising R&D engineer based in Beijing with ~8–10 years of full-stack and distributed systems experience, currently leading the Global Ads team at ByteDance/Pangle. He has driven high-availability ad delivery at massive scale (QPS growth from 10k to 600k) and cut SSP integration time from one week to one minute while implementing smart allocation strategies that reduced CPU by 30% and P99 latency by 200ms. Equally comfortable across Go, C++, Python and frontend frameworks, he combines hands-on implementation with platform-level thinking—building CI/CD, ELK observability, and component libraries in prior roles at Alibaba and CanYa. A pragmatic leader and mentor, he has onboarded multiple engineers and owned end-to-end systems from blockchain-backed DApps to global ad networks.
