- Significantly decreased response time of the app by implementing a message queue (RabbitMQ).
- Implemented efficient and rapid search of different entities for users. By using Elasticsearch, it's now possible to easily scale the system.
- Implemented complex logic for different kinds of recurring events. We used the iCal library (RFC 5545) for this purpose.
- Optimized database queries. After a thorough code review, I identified problematic areas that were slowing down the app.
- Successfully fixed issues with missing data in the database for Hangfire. There was a long-existing bug that caused clients to lose some of their notifications.
Took part In development of web apps on ASP.Net Core with Entity Framework Core (MSSql) + React for clients from USA and Europe.

One of projects was started from zero and now is successfully released and used by customers. There I was developing databases via EF Core, Elastic search + back end logic via ASP.Net Core + front end on React.

Another one is a platform which exists for a longer period of time. I provided support (UNIT Testing, bug fixing) and release of some new features there.
Would not consider working on projects that run operations/have employees in Russia.
