포트폴리오

- Was involved in the development of Vacation Rental Search Engine.
- Built the website based on React.js, MobX, Node.js, GraphQL, and PostgreSQL.
- Mainly handled the front-end part and built the pages based on Bootstrap framework.
- Extensively created the styles for each component using styled-component.
- Also created the hybrid mobile apps for both Android and iOS platform using React Native.

ReactRedux - E-commerce App

- I was the lead Front-end developer in this project. There were around 5 developers - 2 Back-end developers, a designer, and the project manager.
- I developed all the front-end pages from scratch.
- I was provided with the design files as InvisionApp and Sketch file from the designer.
- The most challenging part of this project was to customize the Bootstrap framework.
- It took 6 months to finish the front-end pages.
Technologies: React.js, Admin Dashboard, Bootstrap v4, SCSS

React.js Admin Dashboard Development

I was involved in the development of core engine for these websites. I mainly worked on the front-end part of this project and developed npm modules specific for this company.
I used React.js / Redux to build components and used these components in the various parts of the Wordpress site. The key components are HPS(Home Page Search), FTS(Free Text Search), SRP(Search Result Page), and VDP(Vehicle Detail Page).
For VDP, I integrated AMP(Accelerated Mobile Page) to create mobile-friendly contents specifically for mobile devices.
All these components are integrated into Wordpress using custom plugins developed by the team.

React.js - Car Dealership App

The client provided ready psd layout templates and needed them coded in HTML. The design presupposed a fixed sidebar for desktop. I used Less as a preprocessor, Bootstrap 4 (client's specific request), JQuery, JS and animation libraries for a light animation.

HTML Pages for a Real Estate Project

ClickToEat is a food delivery web application created to help restaurants widen their audience and increase the turnover of their dishes. The website is designed to be easily compatible with smartphones and tablets as well. The users select items from the menu, add them to the cart, pay, and wait for them to be delivered. The website has an admin panel where managers of each restaurant can view and edit the information about:

products;
menus;
prices;
customers;
orders.
The users can choose any dish from the menu of any restaurant in the system and purchase it by selecting:

the product itself;
the product’s quantity;
size and other features;
delivery or pickup address;
time of delivery or pickup;
payment options.
