About

Professional summary

I am an Infrastructure and Storage Engineer with hands-on experience designing, deploying, and operating large-scale CDN, streaming, and distributed storage platforms.

I have supported production media systems handling more than 6 PB of storage, peak traffic of up to 1,000 Gbps, and over 150,000 concurrent users. My experience includes live TV, catch-up TV, time-shift TV, and VOD delivery platforms.

I specialize in distributed storage technologies including Ceph, LizardFS, MooseFS, Dell ECS, and S3-compatible object storage. I design storage architectures with scalability, availability, redundancy, and capacity expansion requirements in mind.

I work extensively with Linux infrastructure, networking, caching, CDN architecture, virtualization, and high-bandwidth systems. I am experienced with TCP/IP, DNS, Anycast routing, NGINX, VMware, KVM, and OpenStack.

I also use automation and observability tools such as Ansible, Prometheus, Grafana, and ELK to improve operational reliability. I am comfortable independently solving production issues, collaborating with teams, and working with hardware vendors on infrastructure validation and troubleshooting.

I hold CCNA and LPIC 1-2 certifications and have completed HSK4 Chinese certification. I bring strong problem-solving, teamwork, and infrastructure planning skills to complex production environments.
