Featured Case Study
TEAM Informatics
PrizmDoc Viewer enables expert enterprise content management with modern and customizable APIs.
I work with PrizmDoc Viewer on a day-to-day and week-to-week basis. It’s easy to implement, and it saved us time and effort from a development standpoint. The fact that it’s HTML5 was a big thing for us and the public documentation is very, very strong. A lot of companies say they will do it, but Accusoft has the code snippets and demos to prove it.
Nick Molchanov, Software Development Manager for the PrizmDoc Viewer product group, graduated from the Moscow State University in 1998 with a degree in computer science. Nick joined Accusoft in 1999 as a software engineer for the ImageGear product and contributed over a decade of his career to help build a strong SDK product line before joining the PrizmDoc Viewer team. Nick is also a Certified ScrumMaster® and is passionate about fundamental agile principles. He has been practicing agile with his distributed teams for many years now before it became a standard for many organizations. In his spare time, Nick enjoys rock climbing, playing soccer, and spending time with his family and friends.
