• Member of Core Networking team, developing networking infrastructure for network aggregation product aimed at cable operators, etc.
• Designed and developed facility for compressing TCP packet headers to save bandwidth.
• Designed and developed TCP/IP proxy module, that operated as a full TCP/IP stack on either end of a proxied connection, with data forwarded over one or more network interfaces (e.g. wifi and cell) in between, via a.
• Wrote unit and integration tests for the TCP/IP proxy module.Developed in C++14 on MacOS and Ubuntu Linux platforms.

• Member of Internet Firmware team, developing control and reporting systems for millimeter-wave wireless networking hardware, targeting an ARM-based embedded system running Linux.
• Developed facility to report packet rate histograms from wireless interface kernel driver via Collectd, from all supported 802.11 data rates.
• Designed and implemented new Collectd plugin for reporting signal strength from wireless interfaces.

• Senior Software EngineerMember of Cloud Optimization group, developing a Linux-based on-premise appliance for delivering Akamai services, including caching and optimization, to Enterprise data centers and branch offices.
• Designed and implemented statistics collection and reporting application in C++, backed by an SQLite database.
• Designed and implemented statistics reporting client libraries in C++ and Perl, which are used by all applications on the appliance to report statistics and traffic to the collection application.
• Redesigned and rewrote statistics reporting component of packet routing application, via an object-oriented design implemented in C. This included: o Aggregating multiple different data sets from multiple worker.
• Designed and implemented facility for collecting packet captures on the appliance in a secure and transparent fashion, including infrastructure for running and managing processes and streaming the output to a central.
• Designed and implemented a facility in Go to automatically renew the appliance’s DHCP lease when the network interface configuration changes.

Designed and implemented enhancements to network traffic statistical analysis library.Worked on integrating Sandstorm protocol parsing and application reconstruction engine into Niksun products; e.g. integration with NIKSUN regular expression packet search facility. Designed and implemented parsing modules for extracting content of webmail submissions.

Designed and implemented database modules and network protocol parsers in C for OSPF, BGP and RIP routing protocols, for reconstruction of network map from captured packets. Designed and implemented C++ back-end code for LCD display of status updates, for headless operation of network analyzer product.

Principal engineer responsible for enhancements and ongoing development of large automated software testing infrastructure, developed almost entirely in-house. Infrastructure performed several thousand unit and system tests nightly of disk-based archive storage system, on farm of 500+ testing servers.Designed and implemented new test suites for testing.

Volunteer member of Media Lab research group developing tools, infrastructure and platforms for wearable computing.Designed and implemented enhancements and new features for experimental wearable computing platform.Integrated SSL security protocols into distributed interprocess communication infrastructure.

Designed and implemented a major redesign of Jewel Thief (clone of Bejeweled), one of Gamesville’s earliest Java-based games. Redesign was aimed at improving gameplay and visual interest so as to increase player retention.Designed and implemented Magic Pyramid, a Java-based card game. Both games involved extensive graphical manipulation, including.

Designed and implemented policy monitoring and reporting system, for FreeBSD-based network QoS platform. This included a back-end based on the Berkeley db database library, a collection system built into the user-space device management system, and a reporting library for extracting data from the database and performing the necessary calculations to return.

Finished port of DOS network analyzer product to Windows NT and Windows 98 platforms.Designed and implemented major improvements and revisions through two major releases.Designed and implemented companion throughput monitoring application, which displayed a tree of the protocols found on the network, and allowed the user to generate graphs of throughput.

Member of development team for implementation of IPSEC/ISAKMP security protocols for the Windows 95 desktop.Integrated separate Windows NT and Windows 95 implementations of Socks firewall-traversal protocol to common source base.Ported IPSEC device driver from Windows 95 to Windows NT.Did extensive compatibility testing of IPSEC implementation with.
