My name is Edward Ombui. My background is in Computer Science (CS): BSc Computer Science and MSc Applied Computer Science. Apparently, CS and generally computing has several mathematical courses including Calculus (Integral and differential), Linear algebra, Statistics, Discrete maths, and other math mainstreamed courses.
The combination of math and computer science knowledge enables me to better view, analyze and understand the relationships among objects around my world. 

I officially joined the vCalc team in January 2014  to head the vCalc's Technical Support (vTS) team as the vTS Manager. The vTS team consists of 5 individuals (me included) whose role is to offer 24/7 online support to vCalc users around the world. In addition, vTS supports vCalc's software engineering team by doing regression analysis and other software testing before the release of any vCalc updates.

From time to time, I am involved in marketing vCalc to institutions of learning : universities, colleges and high schools. Here, I get to demo vCalc's powerful features for content development and social collaborative capabilities. Last April , I made a presentation to an enthused group of Alliance High School students (One of the the top national high schools in Kenya) as i demonstrated how vCalc can be used to not only access content but also develop content for different subjects through the programming platform on vCalc.

vCalc has a Feedback link (on vCalc 1.0 version) and Contact us link ( Wiki version) at the bottom of the landing page which enables vCalc users to either report a problem, suggest an enhancement, request new content, report a violation of terms of use, or any other feedback not covered in these categories. The vTS team receives these feedback through a ticketing system and are able to expeditiously respond to each ticket and escalate persisting issues to vCalc's software engineering team.

I have found vCalc to be a very powerful online tool that not only gives me access to rich mathematical resources but more importantly enables me (as a teacher or lecturer) to connect & collaborate with students in creating and freely sharing multidisciplinary content in form of equations, datasets, constants and calculators. I currently have over 70 vCalc connections (colleagues) with whom we share equations, calculators, constants and datasets across disciplines , including Psychology (see the Personality Calculator-True Colors) and others like a calculator to help you budget for your wedding (see the Wedding Budget Calculator)
