An AngularJS-based web application for an online directory of a wide range of businesses that can be reviewed and checked by anyone.

This application supports profile creation, reviews, and comments on different businesses. Users gain different levels of badges based on the experiences they shared and are also allowed to upload photos and bookmark favorite businesses. Sharing is supported on all major applications. The application is compatible with all platforms including mobile devices and old browsers.

An AngularJS-based web application for creating real-time simulations in browser, with data provided from seismic sensors and drawing waves and effect on map using ArcGIS API. For calculation, it uses Graham scan (algorithm) in order to get more realistic areas that were affected by an earthquake.

An AngularJS-based web application, a generator for manipulating words and sentences in order to create funny letters from a serious business one. With the simple configuration file and list of words that will be replaced, the generator that was built in code is reusable and simple to modify. Also, the admin is able to modify the percent of modification that can be made by the generator.

Built in pure JavaScript to get the best performance, this website application manages the daily/weekly/monthly plan of each worker and client. This application calculates available hours and pause offsets for each worker based on previous and next tasks that are already scheduled. Simple drag-n-drop brings each task to the calendar view, automatically applying new offsets for start and end time in the defined working hour scope.

A website application, built on a customized Backbone library, that allows users to create boards and use each of them for creating and gathering different types of items from the cloud, with Dropbox and Google Drive, from stores like Amazon, music services like Soundcloud, and user desktops. I was involved in the UX/UI development and integration. My responsibility was to implement core architecture.

An online TV channel that provides custom videos for one particular sport. I worked on the dynamic elements of the application responsible for the video player, the relationships between galleries and players, and communication with the back-end. The main gallery has different states of rolling "currently playing" video on the first position in the first row from the second row.

A system for an aviation company that required three completely independent content management systems and two websites for customers and employees. I worked on one of the content management systems built for planning plane routes, registering routes with airports, calculating expenses, and finding the best and the cheapest routes for traveling. My responsibility was to organize the front-end core architecture. I also developed major functionality and coordinated team efforts.

Three projects related to annual reports and promotion for two large global corporations, with a goal of covering a wide area of platforms, browsers, and media sizes with a static, single page which had to be fully resizable and quick loading. Each project has about seven pages arranged in one line on the Body element, with the active one in focus and the others locked to the side like stacked pieces of paper.

An application for gift sales. The company has a wide range of clients and customers and gives clients an opportunity to gain more sales for their products worldwide without pushing customers to go to stores. Everything is done via online payments and vouchers. My work was based on the content management system for this application, building a fully customized editor that gives clients the chance to create their own promotions and publish them independently of the main system.

An application for a cinema advertising company that provides premium marketing and media solutions for advertisers and comprehensive representation of the cinema's advertising partners. I implemented the website application giving customers an opportunity to register and review/rate movies and to take part in the weekly quiz to get free tickets for the latest movies. The user is able to search movies and check theater locations by proximity to a zip code.

An Android application for creating custom bracelets in 3D with ordering and payment mechanisms. I implemented a Shopify API and PHP RESTful service that provides all the data from the Shopify store server related to products and prices, as well as communication with another server where the 3D models and other application data is stored.

I was a software engineer on this project. My responsibility was the development of new features, components, and optimization. Besides React on the front end, I had to develop, maintain, and support the development of new features on the back end with Node.js and GraphQL.
