“Yitzchak has provided well balanced, and high standard management of the PerlMonks educational and professional development website. I have observed his outstanding capability as site administrator, and have been a personal witness to his elevated abilities in system administration, system development, planning and implementation of site policy, development oversight, editing, and documentation. Additionally, his willingness to share his expertise has helped to train literally thousands of individuals seeking a deeper understanding of programming and specifically programming with Perl. Through his administration and his public instructional discussion, I have gained first-hand experience that leaves me comfortable recommending Yitzchak for any programming, and systems administration responsibility. He maximizes his accountability and effectiveness in his areas of stewardship, and is both brilliant and easy to work with.” February 7, 2007

“Yitzchak's opinions on the wiki have been well-considered and valuable in creating a consensus, and he's shown good judgment in just doing things that don't need to be agreed upon by the administrators in advance.” February 5, 2007

“Yitzchak is a world class software engineer and you should be thrilled at the chance to have him work with you. He has proved over several years as a Perl 5 Porter that he has an excellent and in depth knowledge of Perl 5 and its internal operation at the C level. He's one of the very few that truely understands how perl works at all its levels of operation including the internal virtual machine. His sense of maintainable code is impeccable and he has a body of work on perlmonks.org showing a consistent ability to teach and lead junior programmers. At WhitePages.com Inc, he was a highly valued resource. I consulted him for my toughest problems and so did the rest of the office. At LinkedIn.com, you'll see additional recommendations from his co-workers on his stellar performance. Truely, this man rocks. If you have tough problems, you want him tackling them for you.” February 4, 2007

“I received several glowing recommendations for Yitzchak prior to interviewing him and it didn’t take long after he started to see why. Yitzchak has an incredible depth of knowledge in several technical areas and uses that skill to help others make good decisions and develop quality products. Not only will Yitzchak’s technical acumen help any company improve their product, his personality is a true morale boost for those who are lucky enough to work with him. While Yitzchak has only been gone for a few short weeks, his presence is already missed. I look forward to working with Yitzchak again some day.” February 5, 2007

“Every employee is an investment. Some of them pay off quickly, some take some time, and some are just duds. Yitzchak was a "home-run hire" - our (not inconsiderable) efforts to recruit him were paid off within days of him joining our team. His depth of knowledge and problem-solving skills, not to mention his amazing intellect, were immediately brought to bear not only on the tasks we assigned him immediately, but also on helping everyone else on the team. Not only did he do an amazing job on the projects he was assigned, he pitched in and helped out across the board. The recommendations from his co-workers illustrate the level of respect they had for his knowledge, as well as the teamwork ethos he brought to the group. I look forward to having Yitzchak on my team again - I have full confidence that he will once again pay off handsomely for my efforts!” February 4, 2007

“Yitzchak was referred to me by one of our Architects. His reputation in the Perl community was immaculate and well known. I contacted him and subsequently was involved in his hiring. His demeanor and conduct during the interview process was absolutely exemplary and forthright. I found him to be without guile or deception, which allowed us both to be straightforward with each other. This made the hiring and on-boarding process very trouble-free. Afterward, I learned that Yitzchak was a very consistently high level performer, as witnessed from the positive comments made by his peers. He is also quite personable and easy to work with. His coding and mentoring have been a huge help to our diverse (skill-wise) group of developers, and all aspects of his work are thorough, well thought-out and complete. I give Yitzchak my highest recommendation.” January 16, 2007

“Yitzchak is an outstanding individual. I came to know him through the Perl programming community, where he volunteers countless hours improving the core Perl system and giving advice and help to fellow Perl programmers. While working with him, he repeatedly brought critical insight to the problem solving and software design process. Yitzchak has a very thorough understanding of software design and of the Perl language and runtime engine. I have learned much from him, and look forward to learning much more.” January 15, 2007

“Working along side Yitzchak over the past months has been, perhaps, one of the most educational experiences I have had at any company. His keen ability to quickly research any problem combined with his overwhelmingly deep knowledge base and technical ability made him one of the most valued members of our team. I personally find it to be a deep tragedy to have lost him. His contributions to our code lines, both in code written and thoughtful approaches taken are still unparalleled to any other I have worked with at WhitePages.com. Given the opportunity, I would not only work along side Yitzchak again; but recommend anyone to work with him in the first place.” January 15, 2007

“Yitzchak is one of the smartest and detail-oriented people I know. He came into Whitepages and understood how it all worked (with both suggestions on how to improve it And fixes for bugs we didn't even know existed) within a week! Yitzchak is easy to work with and has a friendly disposition with none of the argumentative grandstanding you sometimes see with people of his caliber. I highly recommend him and would be delighted to work with him again in the future.” January 14, 2007
