I have worked on the system for trading in fixed-income markets. The system calculates risk, DV, PnL, etc. I migrated the monolithic system to microservices. It has optimized space storage and calculated trades faster. I made the observability of the system better via Grafana graphics and notifications. These graphics include technical and business information. I also created and implemented custom reports for recognizing unnormal source data.
