Aug 2017 - Present

Worked on implementation of maps, filters and layers with OpenLayers API. After completion of first stage of features, optimized codebase, configured webpack, improved development and build process. As a part of second stage of features, designed a widget for layers, processing new data (height of the earth's surface), adjusted map’s controls and parcel’s statistics.

front-end: react (redux) Implemented task manager for company purposes, based on Redmine API to improve tracking of assigned tasks and make time management simpler. My goal was to create a dashboard, based on data about users and theirs tasks. Application brings advanced filter functionality, based on start date, end date and time interval. Client can drag and drop tasks to change assignee or task category.
