Under my lead, our team developed a Client/Partner zone (.net), backoffice with multilevel marketing system with 8 levels, multiple client and partner types. Provisions per level and per product type. Online training courses for partner + registration, fees, exams evaluations and questionnaires both manual and automatic. • Private cloud based on VMware located in Switzerland, DDoS protection, private VLAN between 3 separate locations, load balancing and CDN (Europe, ASIA) using Akamai and Cloudflare

For a client from EU, my team created an universal solution for Crypto Currency Exchange with plugable data sources, wallet providers and liquidity providers. Everything is modular and easy to configure. All 3 main types are available including client co client exchange.
Backend and frontend are both .net core, we are using API first approach, so backend, front end and mobile apps are using the same API. We used a heavy data caching using Redis cluster.
Frontend is a clean "no framework" approach with vanilla JS. Backoffice uses jquery, bootstrap 5. The backoffice includes a task system (ticket system), admin user rights/module management, knowledge base (wiki) and company managemend including employess management + training system..
