Profile bio

About Greg Templeman

Need a cybersecurity-software expert? I've written data analyzers and feature extractors for most of the file formats in common use: PDF, Microsoft Office, RTF, executable files, and more, analyzing most files in under a second yet feeding AI models that have close to 100% accuracy. I've written static analysis for Unix ELF executables, to extract critical machine code sequences for detecting novel malware. Knowing how to find meaningful data features for effective machine learning is the secret sauce of effective deep learning, especially in the complex, ever-changing world of malware and cyberattacks.I am a detail-oriented C / C++ and assembly-language expert skilled in designing and implementing high-quality, cross-platform, multithreaded software. Adept at understanding, supporting, and improving large, complex code bases, both individually and in global teams. Exceptional creativity, problem solving, optimization, and troubleshooting skills yield long-term benefits in code reusability, performance, and reliability.

Listed skills include C++, Linux, Multithreading, C, and 38 others.

A career timeline built from the work history available for this profile.

Principal Engineer

Current

Foster City, CA, US

Oct 2022 - Present

Software Engineering

Sunnyvale, CA, US

* Designed and implemented a generic, hierarchical feature-tree library, based on key-value atom pairs appended in multiple depths and with multiple, optional attribute modifiers. This library provides a simple, flexible way to specify a feature-file vocabulary, and provides plugins to both generate a list of candidate, aggregate (hierarchical) features.

Jun 2018 - Oct 2022

Software Engineering

Sunnyvale, CA, US

* Designed and implemented a high-performance, vectorized, multi-format, obfuscated-file scanner, able to detect and extract all Windows, Unix, and Mac executables, PDF documents, Microsoft Office CDF and OXML format documents, Java class and JAR files, ZIP files, and all three Adobe-Flash variants. Detection and extraction occur no matter where such.

Jun 2018 - Oct 2022

Software Engineering

Sunnyvale, CA, US

* Designed and implemented a PDF feature extractor, which looks at the entire hierarchy of PDF-file objects, considers their relationships to one another, and generates a multi-level feature tree, with additional attribute modifiers at the leaf nodes. Designed to run in both training mode (generating billions of candidate features) and model mode.

Jun 2018 - Oct 2022

Senior Staff Engineer

Milpitas, California, US

* Implemented X-macro based, automatic table generation/maintenance design to speed development and eliminate substantial human error maintaining interrelated logic tables. This dramatically simplifies adding / changing compiled features, state machines, and configuration parameters.* Refactored the streaming, network-analysis engine to work with a custom.

2013 - Jun 2018

Senior Staff Engineer

Milpitas, California, US

Main architect and software engineer for the multi-flow network-analysis engine sub-system of FireEye’s network appliances. Developed and improved high-performance HTTP and application-file parsing “on the wire” to observe features and render a pre-filtering verdict about suspiciousness of HTML, Javascript, PDF, GIF, Flash (SWF), and various.

2013 - 2018 ~5 yrs

Senior Staff Engineer

Milpitas, California, US

* Designed and led implementation of a persistent, new-second-level-domain tracking system, with learning-mode heuristics and adaptive-limitation mechanisms to avoid over-submission of samples from these domains. This code now regularly catches malware that used to require signatures to detect.* In-house, Hack-a-thon project successfully demonstrating.

2013 - 2018 ~5 yrs

Staff Software Engineer

Efi

Londonderry, NH, US

Developed and improved code underpinning Fiery Server and embedded controllers, including file and data security, multi-process / multi-thread management and communication, application-startup sequence, built-in debugging and diagnostics facilities, and field engineering logs. Built and extended OS-abstraction layer allowing optimal, system-independent.

2010 - 2012 ~2 yrs

Lead Software Engineer, Efi Print Systems Group

Efi

Londonderry, NH, US

* Designed and extended networking / socket abstraction libraries, including proprietary, inter-system communication protocol and in-house-network detection / security. Leveraged to implement remote, interactive debugging tools for embedded and auto-test systems, and to split code between user mode / Session-0 for Windows 7 compatibility (allowing quick.

2007 - 2010 ~3 yrs

Senior Software Engineer, Efi Imaging & Compression Group

Efi

Londonderry, NH, US

Continually extended and optimized rasterizing / compression software to improve functionality, flexibility, performance, and reliability. Developed novel imaging / compression implementations and algorithms for faster / better raster rendering and printed output.* Architected and implemented back-end code for working prototype of arbitrarily-extensible.

2002 - 2007 ~5 yrs

Core Technologies Software Engineer, Efi Imaging & Compression Group

Efi

Londonderry, NH, US

Redesigned and converted rasterizing / compression software to multithreaded architectures. * Redesigned and re-implemented rendering / compression sub-system creating EFI’s 1st multi-CPU architecture, including refactoring for thread safety, advanced memory management, and system flexibility. Resulted in 35% faster system performance overall.* Designed.

1997 - 2002 ~5 yrs

Senior Software Engineer

Logicware

* Designed, managed, programmed, and maintained multi-threaded, multi-network, industrial-control interfaces and embedded-control systems.
