I worked in my previous job for 6.5 years. During that time I did a lot of different tasks, coming up with various architectural solutions. The project was an eco-system of products for trading area. It was a complex, multitenant highload project, that consist of different parts, like CRM, client portals, web trader, support portal. Of course, it was a real-time system, and the frequency of events on the frontend reached as much as 90 per second, so it was a challenge to keep browser rendering fast.
No procrastinating with interesting tasks
