# Jingjing Zhang > Software Engineer Location: San Jose, California, United States Profile: https://flows.cv/jingjingzhang ## Work Experience ### Software Engineer @ Lacework Jan 2023 – Present Data ingestion in lacework's cloud security platform 1. Increased the resource coverage velocity 20+ times by automation and code-generation in 6 months. 2. Added real-time monitoring, tracing, and alerting into lacework’s resource collection system; This effort has significantly reduced our time to detect incomplete data collection and speed up the time on mitigating the issues. 3. Designed, implementing a configuration system allowing the system to dynamically read configs from database, and hence paved the way for our system to be self-serve ### Software Engineer @ Facebook Jan 2018 – Jan 2023 | Menlo park, ca Logging: designed core data encoding, public logging API, and sampling strategy for Meta’s logging platform. Helped saved 2%+ global cpu (~$6M capex saving) with type safe API redesign. Data schematization: Changed the entire data warehouse’s serialization format from hive text serialization into thrift based binary serialization. Migrated 100% of data logging into the new system. Tracing and metrics governance: Designed and implemented explicit tracing library for integrity review system; Initiated and designed automatic metrics governance system. Ingestion: Worked on auto scaling resource manager of data ingestion jobs in the entire warehouse, which ingests ~4B events/sec, 4TB/s data using 30k machines ### Staff Engineer @ Huawei Technologies Jan 2015 – Jan 2018 Working on SDN, NFV, and cloud solutions for access networks. Mainly working with open source projects, e.g., ONAP, ODL, ONOS, OpenCORD, OpenStack, Docker, OVS, OCP, etc. *SDN: high-efficient intent-based SDN controllers for access networks taking advantage of the tree topology. We do POC demo of the efficiency of our controller and sharding algorithms. *NFV: investigated, developed, and compared performances of VNF performances with OVS and VPP. *Cloud: developed micro-service based virtual network function by using various open source components such as consul, zookeeper, kafka, docker swarm etc. Awards: 4 patents pending on SDN controllers for access networks and in-band network telemetry. Network BU "Golden Network" Award - 2017 ### Software Engineer @ Epic Jan 2014 – Jan 2015 ### Software engineer @ Arista Networks, Inc. Jan 2012 – Jan 2013 Mainly working on the design and development of ASIC-based packet forwarding engine software, a key component of Arista's Extensible Operating System (EOS). I have implemented the following features in Arista's switches: 1. advanced port mirroring feature in Arista’s 7150 series switches. 2. buffer management in Arista’s 7050 series switches. 3. SNMP support for shared-memory queue counters, Arista-queue-mib definition and implementation. 4. optimized the TCAM usage in programming ACLs in the chip. My specific tasks include: • Gather functional and technical requirements; write functional specifications and design specifications. • Independently implement solutions for packet forwarding engine using C/C++ and python in Linux. • Write test plans and implement automated test programs to execute the cases in the test plans. • Triage and fix problems found by test programs and problems occurring at customers’ networks. • Maintain multiple infrastructural packages in the Arista EOS modular software system, to ensure robustness, efficiency and manageability of these packages. ## Education ### Ph.D. in Electrical Engineering New Jersey Institute of Technology ## Contact & Social - LinkedIn: https://linkedin.com/in/jingjing-zhang-27398818 - Portfolio: http://web.njit.edu/~jz58 --- Source: https://flows.cv/jingjingzhang JSON Resume: https://flows.cv/jingjingzhang/resume.json Last updated: 2026-04-10
