Analytical Platform for Thinfilm Electronics

CNECT app is a strategy constructor that allows users to configure different actions based on using NFC tags manufactured by Thinfilm. For example, a marketing activity constructor tracks counterfeit products, observes product taps (scanned NFC tags) in real-time, and analyzes user actions by variables such as location, activity, engagement, time of day, and tap frequency.

Uteki

Uteki is an application for a Japanese cosmetics manufacturer, built with Vue.js and
Nuxt.js. As a full-stack developer, I implemented the REST API service and developed the front-end. I also created the site administration UI based on the Strapi package.

Catalog for a Kitchen Set Manufacturer

https://smenakuhni.ru/
This website, written in pure JavaScript without any framework, is responsive for all devices. I developed the site layout and form submission and validation logic. We paid a lot of attention to performance optimization because the main catalog page contains images of different sizes.

Landing Page for Kitchen Set Manufacturer

This website, written in vanilla JavaScript, is responsive and adaptive for all resolutions and devices. It required performance optimization because of the huge number of images on a single page. I also created a CMS-like system based on the configuration of a JSON file.
