Software Engineer
Integromat
- Created integrations with many different online services via their APIs and the core system to allow users to use these online services within Integromat using Node.js and JavaScript.
- Created and led the development of the Integromat Apps Platform, which allows users to write their own integration without any programming knowledge using Node.js and JavaScript. The platform became so successful, that, due to many benefits, it was used to build internal integrations as well. This decreased the development time of integrations by more 3 times.
- Led research on containerization with Docker to allow for easy deployment of Integromat in private data centers.
- Set up a CI workflow using CircleCI to allow for more confidence during deployments.
- Improved logging and log aggregation and analysis to allow for better error resolution.
- Improved monitoring by setting up Datadog to allow for better visibility into the system and proactive maintenance.
- Created a transactional data storage module that uses MongoDB in Node.js and JavaScript.
- Worked on an experimental communications protocol with WebSockets using Node.js and JavaScript.

Experience
iflix Progressive Web App
https://m.iflix.comI 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
https://www.integromat.com/en/developersWe 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.
