Projects

Sportsbook Risk Management

  • Implementation of the new version of the Asianmonitor app - modular and easily extensible single-page app with PHP and JS (w/ jQuery).
  • Introduction of Babel and Sass for an improved workflow.
  • Improved the UX and provided constant feedback to the team and the designer.
  • Development of the new Asianmonitor homepage, help docs, and demo page.
  • Creation of the admin dashboard with real-time app control, news, and notifications.
  • The continued support and development of the Asianmonitor app (slack integration, theme, localization, additional tools and modules, optimizations of the existing code and security improvements).
  • Responding to the client’s feedback and support.

Achievements

The initial systems and modular design enabled us to add new tools easily, which allowed us to respond quickly to clients’ feedback, iterate on tools design and improve the app consistently without any operation interruptions or large code refactors.

The custom design and the constraints of not using any frameworks and plugins (except jQuery) led me to create several internal systems that fit the app’s needs without extra overhead. I’m proudest of the system we have in place for creating and drawing out graphs on canvases with user interaction and read-out of changes with smooth 60fps animations.

Odds Comparison Tool

  • Implementation of the dedicated mobile version.
  • Updates to the existing desktop page with new modules and styling changes.
  • Adaptation of the page into PWA (Progressive web app) and later to the TWA (Trusted Web App) for Android mobile devices with a service worker and web push notifications.

Achievements

Navigating the quirks and inconsistencies between devices and browsers in mobile space was challenging, especially with the amount of data Betmonitor had to show neatly on screen at any given time, but we were happy with the result.

Premium Odds Comparison Tool

  • Creation of Betmonitor Pro, a fully mobile-friendly and responsive homepage for SaaS software, with payments using Paypal API.

Achievements

I’ve built an animation and transition system that was easily editable in HTML with a few predefined data tags and properties (classes, opacity transforms, colours, or any CSS value), which enabled us to design, iterate, and build animation sequences for each section of the page separately.
