This software is compatible with my iPhone making it easy to work while out shopping, at dinner or sitting in the waiting room, if a client needs me.

Software Tuning

“Henry worked with me on the billing system at Akamai [Fortune 500]. 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, Architect at Oracle


“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


Henry is a motivated, forward-thinking as well as intelligent Software Engineer who has lots of knowledge in his field. When you really get to connect with him, you will find an amazing person who cares about his team. Henry leads by example and many people at Revcontent found his enthusiasm and dedication both inspiring and motivating. There was quite a few projects Henry worked on that he was able to take briefly defined requirements and follow them to completion. in addition to getting team feedback and adjusting accordingly. I would highly recommend him for any software or database engineer position.
Chris Maynard, SVP of Engineering at Revcontent

Henry is an Awesome Developer and problem solver and can tackle challenges many wouldn’t dream of taking on but his greatest asset is his zeal for life and as a true Genuine member of a team.
John Lemp, CEO at Revcontent, Partner Nextfund

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, Lead Software Developer at Lime Spot

Henry is a detail-oriented, knowledgeable, full stack developer who has a keen attention to detail. Henry often worked directly with business teams to ensure he provided the best possible solution to the problem at hand.

Post-release he showed his professionalism by following up with them to ensure the solution was meeting their needs and handled any issues which arose.

He has extensive knowledge of backend systems and while at Revcontent, wrote a MySQL driver for the web framework we were using at the time to support enhanced scalability and throughput.

I would recommend Henry without hesitation for any software development or engineering position.

Peter Wilson-Ferrer, CTO at POWR, Director of Software Development at Revcontent

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.
