Individual Contributor with Company-wide Impact
  • Sole owner of the full Ceph distributed storage lifecycle on RISC-V: build compilation, cluster deployment, architecture design, and performance tuning.
  • Designed an end-to-end Ceph automation deployment pipeline — reduced deployment time by 60%, eliminated manual configuration errors, and enabled consistent multi-node initialization.
  • Integrated DPDK userspace drivers and SPDK NVMe-oF storage stack on RISC-V, achieving a 40% improvement in network and storage I/O throughput.
  • Led cross-team infrastructure integration; established a unified monitoring and alerting system (Prometheus + Grafana) covering storage latency, OSD health, and critical metrics.
  • Optimized critical Ceph execution paths based on the RISC-V RVA23 instruction set, leveraging vector and bitmanip extensions to accelerate hot code paths in storage I/O.
  • Owned full-stack design, optimization, implementation, and bug-fixing for chip-dependent Ceph features — covering the complete chain from hardware capability exposure to storage stack integration.
Jul 2023 – Jul 2024
TD Tech Ltd.
Chengdu
Senior Network Development Engineer
  • Designed an L2 bypass forwarding solution — connected 5G modules directly to NICs via an L2 channel, bypassing the kernel routing layer; achieved 30% latency reduction, 50% throughput improvement, and eliminated 100% CPU saturation on hotspot cores.
  • Maintained traditional TCP/IP protocol stacks for communication module peripherals across MIPS, ARM, and x86 platforms; resolved multiple field-reported throughput and CPU utilization issues.
  • Collaborated with FAE teams to diagnose field failures; designed structured test cases to isolate fault boundaries and improve deployment stability.
Jul 2022 – Aug 2023
Chengdu Seanet Technology
Chengdu
DPDK Network Protocol Stack Engineer
  • Designed and implemented a high-reliability custom transport protocol on top of DPDK — purpose-built for proprietary overlay networks with selective retransmission and SACK mechanisms.
  • Built a specialized transport-layer network with self-managed nodes to achieve low-latency, high-throughput private channel transmission.
  • Developed traffic generation and protocol analysis tools for full end-to-end performance profiling and anomaly event tracing.
  • Served as core maintainer of the AECache module — code review, feature development, technical documentation, and protocol version iterations.
Nov 2021 – Jul 2022
Thundersoft Co., Ltd.
Chengdu
Driver Development Engineer
  • Maintained Intel PMD drivers (ixgbe, i40e, ice) within DPDK userplane; fixed 12+ bugs including 3 race condition defects.
  • Implemented the Header Split feature to enable separate reception of L2/L3/L4 headers and payload, improving CPU cache utilization.
  • Developed RTP protocol segmentation for 810-series NICs, enabling direct video payload writes to GPU memory (RDMA-style), reducing latency in video streaming pipelines.
Aug 2019 – Nov 2021
Baicells Technologies
Chengdu
Linux Terminal Development Engineer
  • Developed userspace network configuration management tools (C + Bash) for LTE CPE product lines, covering config parsing, validation, and operation logging.
  • Added MPTCP kernel module support and optimized multi-path routing policies to improve data transmission stability in poor-signal environments.
  • Resolved customer-reported network performance bottlenecks including TCP congestion control tuning and IRQ affinity configuration.
Jul 2013 – Jul 2019
State Grid Corporation
Prefecture-level City
Information Network Operations Engineer
  • Managed daily operations and network planning for municipal-level power grid transmission and communication networks, including ERP, dispatch automation, and video surveillance systems.
  • Led design and delivery of multiple internal technology projects: network upgrades, security hardening, and system integration.
  • Handled network fault diagnosis and emergency response for grid equipment, ensuring reliability of power dispatch communications.
