Diffco built a complex, production-grade AI agentic system and backend for our client's fintech platform owning architecture, AI/ML components, and AI agents in a security- and compliance-sensitive environment.

IT Outsourcing Review from Yana Romanovskaya

Plavno was creating profiles with pulling up a lot of information (clusters). Xunit-based scoring was used when setting up a .NET 2.0 project. Scoring for this format works similarly to Junit. The team extended the products by adding features, fixing bugs. This development can change cluster parameters, cluster management system (current state of the object), customize vectors that lead to this cluster and make predictions.
