Job Experience:

  • Kentik Corporation (Remote, HQ: San Francisco, CA)
    Senior Backend Engineer (April 2021 - December 2022)

    • Developed and maintained tools, APIs, pipelines, and processes to improve metadata quality and reliability. Harmonize third-party geolocation, network operator, malware, spam, and other datasets with customer-provided hints and internal corrections to allow customers to accurately label and categorize network endpoints.
    • Defined and developed new insight templates to help customers understand and visualize patterns and changes in their data.
    • Designed structured document format and associated tools for service descriptors, allowing the engineering team to describe, analyze, and visualize data flows and dependencies within the platform.
  • Touchpoint Restaurant Innovations (Remote, HQ: Palo Alto, CA)
    Senior Engineer (October 2019 - November 2020)

    • Maintain and extend distributed enterprise point-of-sale (QSR/fast casual) backend and middleware APIs to enable new customer and franchisor experiences (e.g. Smart Folio, Zero Contact, etc.)
    • Implemented a variety of security improvements (traceable encrypted cloud storage for financial information, URL shortener hardening, mandatory authentication layers for event distribution, standardizing encryption with AES-CFB, secure code auditing, fuzz testing).
    • Worked closely with infrastructure/operations to monitor and manage a highly available distributed data environment across a heterogenous mix of virtual (AWS) and physical (on-premise) resources at hundreds of customer locations.
  • Oracle Corporation - Internet Intelligence Team (previously Renesys, then Dyn, Inc.) (Hybrid, Hanover, NH)
    Principal Data Scientist (June 2010 - October 2019)

    • Worked with a small research team to develop an extensive suite of data products, pipelines, and tools for realtime and forensic analysis of global Internet topology, evolution, routing dynamics, network latency, DNS, and other behaviors.
    • Developed improved visualization approaches for network maps, performance data, and other derived intelligence to drive stakeholder decision making and communicate observations to a larger audience (including publication at conferences and in major news outlets).
    • Designed, developed, and deployed rapid technical prototypes of data products, APIs, and analysis tools for internal and external customers.
    • Developed a globally distributed network censorship detection platform (in conjunction with the Berkman Klein Center for Internet and Society at Harvard University). Authored, deployed, and maintained software to detect and characterize network interference at multiple layers in the stack, including packet routing, DNS, transparent proxies, and other middleboxes.
    • Designed and implemented a global route monitoring system to process data from hundreds of BGP peers and detect routing changes across the Internet without prior configuration.
