I redesigned forms mobile version, it caused 25% more successful form fillings by users on mobile devices. I created a form constructor developer tool, this constructor allowed developers to create forms 12 times faster than earlier, apply changes to the forms faster and support big forms codebase with simple JSON files. This shortened form creation cycle from 3 hours to 15 minutes, and shortened time to test from 1 hour to 20 minutes which translated to saving 30+ human-hours per month for our team of 5 people. I managed a team of two developers and assigned them tasks. I organized 3 collaborative meetups with other teams that led to 4 features we adopted. I implemented unit tests for the new component’s library (70% coverage), its improved defect rate resulted in a reduction of average release time from 3 hours to 1 hour.

I created an application data flow structure which decreased time to adding new fields to the table from 2 hours to 1 hour. I spearheaded development of a single page application for auctions, conducted analysis of algorithms to improve performance of tables which reduced TTI from 6.1 seconds to 3.6 seconds, this improved UX.
