Suvaun | Health Insurance Brokerage Web Platform

https://suvaun.com/
A large web platform that helps health insurance brokers work with clients and sell insurance plans to them. As a lead front-end developer and a first developer to join the project, I developed the project from scratch. It has been launched in the US market and offers services to most industry players.

The project includes three products with React and Redux-based front ends and Java and MySQL databases on the back-end side. I used Redux-saga and the REST protocol to communicate with the server and webpack for flexible build, configuration, and project optimization. Also, I designed a micro front-end architecture based on Lerna to solve problems of flexible deployment and code reuse for other projects. Finally, I made a successful transfer to new versions of React and TypeScript.

Later, the front-end team grew, and I managed a team of four people. We developed the main product and two admin services that solve the company's internal tasks and provide additional functionality for insurance companies, such as managing clients and viewing deep statistics in tables and multiple charts.

Lectera | An Education Web Platform

https://lectera.com/
An international online education platform that provides internationally approved certificates. As a senior front-end developer, I took part in this project to transfer outsourced development to in-house, establish technological processes, complete an analysis of the performed work, and bring everything into working order.

Following the context approach, the project was based on TypeScript, React, and Next.js. I also started a testing process based on Jest and the React Testing Library, wrote over a hundred tests, and conducted extensive performance optimization.

The project has been successfully launched in production, used internationally in five languages​​, and developed by the internal development team.

Try.Fit | Scanning and Virtual Shoe Recommendation Service

https://try.fit/
A fashion tech project that provides the ability to scan and obtain a 3D model of a person's foot for a subsequent recommendation of the most suitable shoes. The project is used in offline stores and on shoe manufacturers' or sellers' websites.

As a senior front-end developer and co-founder of the project, I developed many of the products. These included a plugin for shoe stores, a web application for self-service terminals located in stores, admin resources, projects related to visualizing and displaying 3D models of feet and shoes, and interactive interaction with them. The main technology stack includes JavaScript, Vue, Vuex, WebGL, Three.js, GraphQL, and WebSockets, and it is used to interact with the server. Finally, I built the process of assembling and delivering content, including 3D models, wrote many of my visualization shaders and tools for optimizing and parsing 3D models, and integrated the VBO binary format.
