  • iflix Progressive Web App

    The iflix PWA allows you to browse and watch iflix content from your browser, as well as add it to your home screen to work with it offline.

    I was a part of the team that was building and improving user engagement for the PWA - ads, banners, messages, notifications, and other promotional and personalized content.

    We also made improvements and bug fixes to the core application and worked alongside the core development team to improve the overall UI and UX of the web app.

  • Integromat Apps Platform

    Integromat has over 500 different integrations. But sometimes customers needed to integrate systems that the Integromat team was not able to build either due to low demand, missing API docs or other factors.

    We set out to solve the problem by creating a simple platform for users to write their own custom integrations. On this platform, users use JSON to describe what APIs to call, what parameters to send, what to extract from the response, etc.... In the end, we delivered a runtime that was powerful enough to integrate almost any API, whether it sent JSON, XML, text or raw bytes. After we realized how powerful the system really is, we decided to create ALL integrations on this platform. Even transition old ones, which were written in JavaScript, to this platform, because it was much faster to write and easier to maintain. Also, all the bug fixes to the runtime automatically affected all integrations, so you didn't have to redeploy them.
