My main professional interest and area of expertise is web mapping, gis and data visualization. The world is full of great, challenging ideas related to the things I'm good at and I see my mission in turning those ideas into reality. I'm lucky that I like what I do and I do what I like. My skills include JavaScript (jQuery, React, Redux, Redux-Saga, Redux Thunk, Ramda, Angular, Vue.js, Ember.js, Backbone.js, Node.js), HTML/CSS, PHP (Laravel, Yii2, Slim, Drupal, WordPress, Craft CMS), Python (Django, Flask, Shapely, GDAL, pyproj, rasterstats, cv2), R (Shiny, Leaflet, sf, tmap, ggplot2), NoSQL (MongoDB, CouchDB, PouchDB), SQL (MySQL, PostgreSQL, MS SQL), GIS (Mapbox GL JS API, Mapbox Studio, Google Maps API, Leaflet, OpenLayers, Overpass API, CesiumJS, CARTO, ArcGIS Javascript API, ArcGIS REST API, PostGIS, pgRouting, ArcGIS, QGIS), Data Visualization (Tableau, Power BI, D3.js, Highcharts, [login to view URL], ngx-charts), WebGL ([login to view URL], [login to view URL], [login to view URL], [login to view URL]), Mobile (Objective-C, Swift, React Native, Ionic).
