"Henry is an expert programmer. We hired him to write a PHP extension in C and he delivered quickly. His code is high quality and well documented. Henry provided consistent and reliable installation support."
--Michael DePetrillo, Smart Payment Plan, 2010

"I was incredibly pleased with Henry's work. Not only was I regularly updated about the progress, the work was on time and well done. I highly recommend."
--Ivan Mora, Owner, Moracon, Inc. 2010

"Was easy to work with, good for talking about new ideas that could be used in work, and an ability to take confusing writing and get clarity out of it."
--Mark Shannahan, Owner, Tatiana Fashions, 2010

"Henry was a great asset to our team. We built and managed a system to track all hits served by Akamai, along with a geographical and temporal breakdown, in real time. This was a serious engineering challenge, but Henry had control of all aspects, and ran the system after I left. He is self-motivated, can make precise vague specifications, and maintains focus until the job is done. I would definitely work with him again."
--Matt Knepley, Research Scientist, 2009

"Henry is a heads-down engineer who gets the job done while also collaborating carefully with stakeholders to ensure what he builds is exactly what they want. He never ceased to amaze me with his breadth of knowledge and his ability to learn new technologies quickly."
--Tim Olsen, Software Engineer, Lead Software Developer, Lime Labs. Engineer, Akamai Technologies, 2009

"Henry worked with me on the billing system at Akamai. He has a nose for speeding up and simplifying code. He worked fluently in a variety of languages including C, Perl, and bash scripts. He worked on many parts of the billing system including the systems for processing logs; for synchronizing the distributed reporting system using ssh; for recording, summarizing, and reporting errors (including a system that used pagers to allow on-call engineers to get 5 different reports of systems status on demand). In one case he sped up the log processing by 1/3 so that the same work could be done one fewer machines."
--Bradley C. Kuszmaul, Co-founder of Toutek, Senior Architect, Akamai Technologies, 2009 managed Henry indirectly at Akamai Technologies

"I connected with Henry through a community film group meeting in Seattle. I brought him in to produce 4 videos for academic research on a tight budget. Henry has incredible work ethics and works at a level of detail that is consistent with the research requirement. With the right opportunity, he'll be able to manage projects at a much larger scale."
--Eva Yao, Professor of Management and Entrepreneurship, 2009
