Portfolio
-
1400 USD Nabo - always home
Web Programming
Worked on the backend for the "mail"/communication system between users. The main focus was on ensuring everything worked stably under load and scaled well.
Created a scalable backend using MongoDB and Redis (cache, fast operations). For file storage — Amazon S3.
… Implemented the search for nearby users through H3 (geo-indexing) to quickly find people nearby. For queues and asynchronous tasks, used Bull — sending emails, SMS (to phone numbers), and mobile push notifications, to avoid overloading the main thread.
Also implemented user verification via passport.
Overall, the task was to build a reliable infrastructure that can handle load well and does not break with an increase in the number of users.

600 USD Camden School Reports Platform
Web Programming
Developed a platform for viewing school reports in London. The main idea is to have all information about schools gathered in one place and easily accessible.
The frontend is written in Vue, without unnecessary overload — everything works quickly and scales well.
We created a custom CMS through which all content can be managed without a developer.
…
All content is pulled through JSON, so updates are as simple as possible — change the data in the CMS and it immediately reflects on the website.
Overall, the project is more about convenience, ease of maintenance, and not having to dive into the code for every edit.
