Ukraine · Kyiv · More than 10 years of experience · Upper-Intermediate ·Published yesterday
Transitioning to MTE, where we developed an ERP system, introduced me to the differentiation between backend and frontend development. To streamline the creation of ERP interfaces, I built my own framework using a combination of PHP and jQuery, enabling efficient resolution of numerous repetitive tasks.
Moving to OneDome, I focused solely on frontend development, with the backend predominantly managed by skilled Java specialists.
While at OneDome, in addition to regular frontend tasks, I implemented SSR on React in 2017, before frameworks like Next.js became widely adopted. This involved integrating with WordPress through a PHP API to fetch data for our website.
At Slidepresenter, my work centered around frontend development and organizing integration with LMS using SCORM and cmi5 protocols. We transitioned from Redux to MbX to enhance the responsiveness of the player interface. There was also a strong emphasis on project test coverage and documentation, including a migration to TypeScript.
In Slidepresenter, my responsibilities extended to translating a part of the project related to the video editor to MobX and TypeScript, along with occasional implementation of new features.
Periodically, I give lessons of Frontend in some schools.
Orchestrated seamless integration VideoPlayer with Learning Management Systems (LMS) using cutting-edge SCORM and cmi5 protocols.
Frontend Rendering Optimization. Utilizing React rendering capabilities, incorporating canvas and SVG and modern CSS features.
