Worked with a distributed team of over 60 developers across the globe to create scalable micro-services to digest large amounts of data for an aerospace company using React.js, Angular.js, Node.js and AWS cloud computing services. Performed 1-week sprints, with one whole sprint at the beginning of each month dedicated solely to planning, research, and documentation. This work was featured in an article by The New Stack and led to a sponsorship to Stream Conf 2016, San Francisco, California to give a talk about findings and solutions.

Design implementation work

Worked on a project for Bank of America where the team was tasked with coming up with solutions on how to better present reports on the site. Personally tasked with overseeing the development of the landing page. Worked along with the lead designer making suggestions in regards to button placement, background colors for better readability, spacing and how to manage content placement for tablet and mobile views, since the landing page was required to be responsive. Once published, the site won a Webby Award.

As a Point Of Sale solution, Delite had a fairly out-dated frontend design. After some analysis, arrived at the conclusion that most of the user-base of Delite used the app from a Windows 10 PC. Led the efforts to refactor the user interface to match the aesthetics and user experience (UI/UX) of Windows Metro design. User satisfaction greatly increased once the re-design was released.
