Software Developer in Moscow, Russia

Project:
I needed to build the cart and checkout pages as well as a gift card module for a large eCommerce business using React/Redux and following the best TDD practices.

Specifics:
• Existing checkout and cart pages were rewritten completely leaving the original design in place to align with the most modern web development practices using React/Redux.
• A large portion of code was cleaned up in order to provide the best re-usability together with improved site performance.
• Test-driven development was incorporated to achieve a great code clarity for other developers working on the project (Jest and Cypress.io).
•We also needed the gift card module registration to be viewable.

Project:
An energy savings calculator application (built with Vue.js) for a company producing cooling solutions.

Specifics:
• This application utilizes multiple APIs—Pardot, Google Tag Manager, Gravity Forms API, Acton, CouchDB, Chart.js—and functions as a progressive web app by allowing users to work with it offline. Gathered data is then sent to the server immediately as the device regains an internet connection.
• I developed this custom solution to allow an easy translation of the entire application by simply editing a CSV file with the translated strings of text.
• The app functions equally well across all devices as well as through a kiosk app on tablet devices.

Project:
This is my resume website (built with React/Redux) that incorporates fully custom code and design.

Specifics:
• Each section of the application is a widget with its design and functionality, which leads to a high degree of interactivity and a nice-looking web page that is a pleasure to use.
• A Fullpage.js plugin was modified to provide a custom parallax effect on each section scroll. Each section offers a smart way to display a large amount of information that is tightly restricted by the viewport borders.

Animation Techniques:
• HTML canvas with JavaScript image processing
• CSS animations and CSS transitions (each technique is optimized to ensure that visual-rich application is as responsive and smooth as possible)

Project:
A marketing website for the digital data processing agency which is full of visual animations and fancy transitions.

Specifics:
• It incorporates a custom-built alert system, which utilizes Google Maps geocoding to display alerts that are relevant to the user as well as complex mouseover effects to play videos forward and backward depending on the cursor position within the alert box.
• I developed custom pagination for the blog system, which allows one to add multiple blog sections to a page which will all be under control of the browser history API—loading the content via Ajax for the smoothest user experience.
• The system allows the user to add data-to-text transforming animations easily to any title on the website as well as the ability to switch the entire look of the website via an option in the admin panel.

Project:
An app that fetches the most recent posts from the Hacker News platform.

Specifics:
• One thing that distinguishes this app from similar ones is that posts are displayed as soon as each one is fetched—not the whole bulk. This improves the interactivity of the app compared to similar solutions.
• Another feature of the app is the fact that it works offline by utilizing the IndexedDB API.
• Custom filters at the top right and infinite scroll make this app a pleasure to use.

Project:
A famous game clone built with vanilla JavaScript using the best practices of object-oriented programming.

Specifics:
• I composed all of the code myself, covering all aspects of the application; this included the requesting frames and ensuring that the app runs at 60 FPS to manage the position, movement, and collisions of all objects.
• I further customized the initial concept to include difficulty levels (defined by the obstacles, number of enemies, and their speed), an ability to choose different characters, and options to remove/reset obstacles with a single click of a button.
• The scoring system was introduced to add complexity to the application.

Project:
This is a PHP application that utilizes the Twitter API and displays formatted posts from a selected Twitter account in a selected visual.

Specifics:
• I set up a cron job on a server which then executes the script responsible for pulling tweets from a preselected account. It then formats the text from those tweets by removing images, emojis, links, and so on.
• The resulting text is then split into a certain amount of lines, and a specific font-size is applied for the message to occupy the container nicely. Finally, the text is plugged into an image that contains the box for that text to go into, and the result is published to the user's account.

Project:
A very design-centered website for an agency specializing in the gym and spa sector.

Specifics:
• Lazy loading was taken to the next level for this project to reach the smoothest user experience possible. Everything, including text, blocks, and images, appears in a certain way in a certain order, to give this website a slick and structured feel.
• The existing plugins (a slick carousel) were customized to fit the client's needs to have the customized pagination behaving in a certain way. One section required two slick sliders to be tied together, resulting in a complex logic and interactions which provide a very interesting user experience.
• A custom sticky sidebar on internal pages and very large font sizes were a challenge to overcome during the development of a responsive side of the website.
• I also added custom parallax effects to further enhance the visually pleasing nature of the website.

Project:
A React web application (which was later rewritten with Vue.js) for an organization providing local learning centers throughout the UK.

Specifics:
• The application is centered around a map, which is created from a very complex set of data. Lower sets of data exceeded 1GB in size, so that data had to be optimized, simplified, split into logical chunks, and efficiently loaded so as not to impact load times too much.
• I used a React and React Router DOM for a smooth app feel and all of the data is backed by a WordPress REST API (which I also developed from scratch to satisfy the client's needs).
• Later the app was rewritten using Vue.js coupled with Vue router and Vuex for a better code organization following the best practices.

Project:
A marketing/booking website for a UK hotel business.

Specifics:
• Efficiently written scripts and CSS animations allow this app to be both visually pleasing and highly performant. The differences between mobile and desktop versions meant responsive challenges, which were gracefully overcome at the very early stages of the development, thanks to very good communication between design, management, and coding teams.
• A custom-written solution enabled a nice integration of the booking engine directly into the web page.

Project:
A large-scale eCommerce project which helped sign a contract with Walmart.

Specifics:
• I built with the Foundation CSS framework and PHP on top of WordPress back end and WooCommerce framework. The initial design has undergone many revisions that required careful planning for the website structure as well as CSS and JavaScript code, to make sure that this doesn't lead to a messy project.
• The checkout page is a completely custom solution that uses the best object-oriented practices and matches the complex requirements of the Walmart team.

Project:
A landing page and a React web application for an industry-changing car leasing platform in the USA.

Specifics:
• A landing page with a beautiful custom parallax effect for a maximum interactive experience for the user. A second version of the landing page was used for A/B testing via Google Tag Manager.
• A complex multi-step React application provides many ways for a user to find their dream car and make the leasing process as easy as possible for every client.

Project:
An auction house web application for finding great deals on cars; it was built using the Meteor framework.

Specifics:
• The application consists of a very complex filtering system that helps the users to find their car easier. It works well with multiple listing types such as buy-now, auction, reserved-price auction, etc.
• Multiple widgets, like a price calculator, were developed for this project to guide users and help them make a much better decision.
