Matching Engine
The matching engine uses algorithms to set the priority of orders from different users based on time, quantity, price, etc., and then executes them. This is the core of the project, as it is responsible for streamlining trading actions taken by the app.
Scalable Back-end
We have used cutting-edge tech and expertise to develop a scalable and reliable back-end for this complex app. There are multiple services, like the Matching Engine, that are independently scalable, facilitating microlevel upgrades.
Codebase
App developed using the mono-repo architecture for the codebase. We have used Nest.js, a Node.js-based framework. PostgreSQL, Redis, Cassandra, and TimescaleDB were some tech stacks used.
