Advantages
Three things I do well
Compliance, hardware, and AI tooling on the floor — eighteen years condensed into three threads
Hardware + Compliance
Currently on-site at China Telecom Cloud, independently handling out-of-warranty server and switch repairs — 50+ units/month, 100% repair completion. Previously led GAMP 5 computerized system validation at Stellular Therapeutics and WuXi AppTec, passing 2 regulatory and 3 customer audits.
AI & Automation
Python / Shell scripts for health checks, log collection, and alerting cut manual repetitive work by 70% and improved alert response by 40%. Claude / Copilot / Codex applied to script generation and incident analysis.

Project Experience
Selected work with measurable outcomes
Two focused projects with clear time windows and quantified impact — large-scale CDN and biopharma GMP validation.
01
Project
Large-Scale P2P CDN Node Optimization
Context50+ P2P CDN nodes across East and South China suffered from low bandwidth utilization, high content-delivery latency, and slow incident response — directly impacting customer experience and bandwidth cost.
WorkRe-engineered the node lifecycle playbook; standardized deployment / health-check / incident procedures. Tuned bandwidth scheduling and cache-hit rules; dynamically rebalanced per-node bandwidth allocation.
ResultMean incident response cut from 1 hour to under 30 minutes; per-node bandwidth utilization up 15% vs. baseline; content-delivery latency down 20%; saved RMB 200K+/year in bandwidth cost; supported 10+ internet-company onboardings with 100% CSAT.
02
Project
Biopharma Computerized System Validation
ContextA biopharma organization needed to validate EBR (Electronic Batch Record), video conferencing, and data center systems to support regulatory and customer audits.
WorkAuthored IQ / OQ / PQ deliverables, risk assessments, and change controls under the GAMP 5 framework across 12 core business systems; built a complete IT asset inventory and operations SOPs.
ResultSupported 2 external regulatory audits and 3 customer audits with no major compliance findings; 100% validation documentation compliance; end-to-end system traceability.
Work Experience
From phone sales to hardware engineer at China Telecom Cloud
Late start in IT but a clear arc: pre-sales → data center → GMP/IT support → IDC → CDN → hardware repair
