Ported a reverse proxy from x86 to Arm, for on-host TLS termination and solved issues related to assembly, compilation and dependencies.

Analyzed latency and throughput of TLS handshake and bulk data encryption on Arm. Profiled on both x86 and Arm to address the performance bottlenecks using perf-event and FlameGraph.

Developed a container orchestration service with specific on-board environment with CPU/GPU control, dynamic network routing and clock synchronization.

Developed L3 software-defined networking for container IP access with Calico/BGP/iptables, featuring IP affinity and floating IP.

Performed end-to-end on-call duty on services and on-prem machines. Automated operation using Bash scripts and Ansible for a state-declaration approach. Solved the single point of failure on the HAProxy API gateway by DNS-level load balancing with Consul.
