Work on 5 interactive multilingual sites. The frontend sites are based on React.js (Gatsby) and completely on strict TypeScript. Communication with the backend took place both via REST and via WebSocket. Work on a backend for 2 interactive sites. The backend worked on AWS: Lambda, DynamoDB, RDS (MySQL), S3, Step Function. Also, I created generic code to work with WebSocket over AWS. Build a database architecture for interactive site functions. Solved the problem of building and optimizing the rating system of users. In our projects, we used Github Actions to automatically test, build and deploy our web applications.

I worked in tandem with a senior and experienced programmer using the advances in modern JavaScript (React.js, Node.js). We jointly developed sites on the AWS platform. The entire backend was mainly created by me (AWS Lambda) including the database architecture (DynamoDB). Also, I fully participated in the development of the frontend part of the application (React.js, Redux). Created and adapted interactive components for WAI-ARIA (accessability) standards. In the last joint commercial project, we used strict TypeScript (were very pleased).

Old site support (PHP, MySQL, JS). In parallel with this, the development of a new site on our own experimental HTTP server (C ++, MySQL, JS).The source codes of the HTTP server are available on my Github profile.

Support for old sites and creation of new sites, such as: new main site, ARG, branded online store.I used technologies: PHP, MySQL, JS, React

It was work at a startup developing an innovative CRM system in the browser.I was a developer and architect of the system kernel and modules for it.Technologies used: PHP (Kohana), MySQL, JS (jQuery UI)
