  • Sport Betting

    A monolithic application, written on C# and AngularJS, that had huge performance and scalability issues. The management team had zero confidence that it was possible to launch it in one year. I took over the project one year before its release.

    During that period, my team and I rewrote and decoupled the monolithic architecture into the service-oriented one. We added a Node.js web server between the front end and the microservices, integrated technologies like Redis and Elastic for caching and Elasticsearch, dropped the whole project on AngularJS, and rewrote it on Angular because AngularJS lacked documentation and stability. This company is now in the top five in Georgia's sampling industry.

  • Sport Betting for Mobile

    To meet its business demands, this app required a lot of lazy loading for dynamic rendering compression and web caching. It had to load tons of data and renew itself every few seconds.

    I wrote this myself, using Angular lazy loading for dynamic routing. I also wrote a caching mechanism, using IndexDB; integrated a service worker for PWA and used this technology for assets caching; created a dynamic rendering mechanism, which rendered chunks of data without static height; integrated Socket.IO; and created a request-response pattern, using observable streams.

  • Provably Fair Betting Game: Adrenaline

    A fast betting app that my team and I built on PixiJS. It was a whole new world for me in web development because I had no prior experience in canvas-based applications. After studying the canvas world, I decided to use the PixiJS framework to deliver the business demands.

    The lobby itself is written on Angular, and the rendering engine is on PixiJS. After releasing a few games like this, we created a dedicated library on PixiJS. The library was generally purposed and had all the functionalities for rendering and adding assets and managing game logic for any new betting application.
