Akamai Technologies

• Domain specialist and primary developer for image and video processing, transformation, and optimization for the Akamai Image & Video Manager product.
• Researched, implemented, and augmented computer vision algorithms for performing “Perceptual Quality” image optimization to maximize image compression without compromising image fidelity as perceived by humans. This process necessitated high throughput and high scalability on general purpose CPUs.
• Developed a source-based, hermetic package manager to manage system dependencies with focuses on portability, patchability, reproducibility, supply-chain management, vulnerability mitigation, and — especially — ease of development. Initially intended to get new technical team members up and running quickly, it evolved into also being our production dependency manager.
• Coordinated with Mozilla and Google to ensure Firefox's support for AVIF images was colour-correct and compatible with the images produced by Image & Video Manager.
• Optimized many image processes to improve the scalability and COGS of Image & Video Manager. These optimizations were as low-level as raw x86_64 Assembly to directly take advantage of SIMD AVX2/AVX-512 with up to 20× improved throughput on the most critical bottlenecks.
• Open Source contributions to ImageMagick to improve AVIF and HEIC functionality as well as bug fixes.
• Co-authored the 2016 O'Reilly Media published book: High Performance Images: Shrink, Load, and Deliver Images for Speed
• Developed a constant and steady stream of developer and support tooling to help simplify developing, debugging, testing, servicing, and selling Image & Video Manager.
• Consulted directly with customers and prospective customers on-site and remotely on technical matters for both support and sales purposes.
• Prototyped, on my own initiative, to concretely show the value of a Functions As A Service (FaaS) compute technology using micro-VMs and a custom Linux distribution able to boot in under 40ms. Focused on multi-tenant isolation, security, and scalability.
• Developed a Java-based web application server framework focused on minimizing complexity, simple debugging, and front-line global scalability. This framework was developed for Image & Video Manager but was then adopted by other products like Akamai EdgeKV and internal tools.
• Developed image optimization features for the Front-End Optimization product that were spun off to create the Image & Video Manager product.
• Designed, developed, and coordinated the integration of the Blaze.io transformation proxy functionality into the Akamai Ghost proxy.
• Promoted from Senior Software Engineer to Senior Software Engineer II and finally to Principal Software Engineer.

Blaze.io

• Software development for the web Front-End Optimization product in a startup environment.
• Designed and developed an automated optimization to execute, render, and cache client-side JavaScript in an intermediary proxy between the client and the origin server in order to reduce browser execution time on end-user devices.
• Blaze.io was successfully acquired by Akamai Technologies in February 2012.

IBM

• Software development for the IBM J9 Java Virtual Machine (now known as Eclipse OpenJ9) Memory Manager (Garbage Collector).
• Improved GC performance by reducing locking, improving thread locality, and developing new strategies for when to tenure objects when using the generational concurrent GC.
• Overhauled GC observability and metrics through the detailed and machine readable but human friendly “verbose GC” system.

• Extreme Blue internship developing automated Java bytecode optimizations for improving application startup time.
• Extreme Blue internship developing developer tools for discovering, warning on, and refactoring source code duplication and almost-duplication.
• EPIC internship creating new developer tooling to collect metrics, organize, visualize, and assign ownership of compiler warnings when building the J9 Java Virtual Machine. This tool was used to bring the number of compiler warnings for a build from tens of thousands to zero in a matter of months.
• EPIC internship developing source control management tooling for the Rational Team Concert (RTC) product.
• EPIC internship developing the Eclipse Graphical Modelling Framework (GMF).
