Experience
Web Application for Designing and Answering Questionnaires
A web application that enables customers to build and design questionnaires and users to answer these questionnaires. It also allows analyzing code and user input or correcting user input to increase data quality, export data, and APIs.
As a full-stack developer, I improved the existing system design and optimized the application by rewriting the front end in React and Redux and the back end with REST APIs. We implemented Logstash to reduce the database size and Elasticsearch as a new solution for faster searching.
The application is now running 24/7 with two load-balanced instances for handling requests. Data gained from the application is helping pharmaceutical companies to reduce the side effects that people have from the drugs.

Software for Elections
The project contained two web applications, admin and client applications. In the admin application, the users entered the result from each polling station while the client application showed calculated results.
I worked as a full-stack developer contributing to creating the algorithm for calculating the mandates based on the country's election law. On election day, millions of users requested the client application, and the challenge was to show real-time results.

eCommerce Website
An eCommerce website for selling books built with nopCommerce open-source platform.
Working as a full-stack developer, I developed more than 10 plugins that extended nopCommerce core functionalities or added new features. The plugins improved e-store management and were built to facilitate the complex configuration of the nopCommerce platform.
All plugins were sold as separate, independent components and increased the company's profit.
