Russian Escape Room Marketplace

I created a website and web applications based on the MERN Stack for administrators, owners of escape rooms, and operators of the call center. People can find exciting escape rooms through this website, book them, and leave their reviews. In addition, the owners can place information about their escape rooms to attract new clients.

This website is Russia's second-largest escape room marketplace, reaching over one million visitors last year. I acted as a web developer, UI and UX designer, SEO specialist, salesman, and support team lead.

Trading Robot
I created an app for automatically trading stocks on the market using the open API of the broker. I used the MERN stack for that. Using the capabilities of the Socket.IO library, the application displays stock quotes and portfolio status and builds charts in real time. I made a Snap package for Linux distributives, so the app is ready to work after executing a single command—snap install trader. It works even on Raspberry Pi and can be updated at any time.

Booking System for the Escape Room Marketplace

I created a MERN-Stack-based app for booking escape rooms on the marketplace website, social groups, third-party websites, the call center, and through the chatbot. As the full-stack developer in this project, I designed and created this app from scratch. I also built a functional and intuitive administration dashboard.

Tasks System for the Escape Room Marketplace

I built a MERN-Stack-based app for creating, distributing, and controlling the execution of tasks to assist the business processes within the escape room marketplace. I was a full-stack developer, designing and building the app from scratch.

Website Chatbot App

I developed a MERN-Stack-based app for processing various user interaction scenarios in a chatbot interface embedded within a website. I was a full-stack developer, designing and building the app from scratch.

Search-engine-optimized Website for the Escape Room Marketplace

I created a MERN-Stack-based website showcasing information about escape rooms. I used React with the Next.js framework to make the front-end part and Express.js, TypeScript, Mongoose, and MongoDB to create the back end. The front end is split from the back end and uses a REST API, allowing the website to have a good SEO and an interactive UX. The fact that I completely rebuilt the website from a single-page application (SPA) based on Anguar.js significantly influenced the SEO of the website.

Content Management System for the Escape Room Marketplace

I created a MERN-Stack-based app to add, store, and update escape room information. The site allows users, even if unauthorized, to add or edit information about escape rooms, including names, descriptions, photos, and videos. All proposed changes are moderated before publication on the site. I designed and developed the whole app from scratch.

Accounting System for the Escape Room Marketplace

I built a MERN-Stack-based app for working with marketplace partners. Partners can check reservations of their escape rooms, adjust prices, and calculate final commissions. Also, they can see all income and outcome operations from their account, check their balances, and receive email notifications when a balance decreases. I designed and developed the app from scratch.

A/B Testing Systems

I built a MERN-Stack-based app to conduct A/B tests on the escape room marketplace. A developer can create different variants of UI and UX and get statistics back on which variant is better for desirable results. The system automatically tracks the efficiency of every variant and adjusts the likelihood of their appearing on the website to gain better results.
