The Problem
What needed solving
The financial market lacked a regulated, institutional-grade platform capable of trading private and digital securities efficiently and securely. Existing systems were not built for the nuances of tokenized assets, requiring a bespoke solution to bridge traditional finance with the digital asset ecosystem.
The Approach
How I built it
Architected a high-performance backend using Go and the goa framework for the core ATS.
Implemented business logic and complex trading rules in TypeScript within a Goja VM for flexibility.
Integrated secure custody solutions via Lux MPC for threshold signing of digital assets.
Leveraged PostgreSQL, Valkey, and NATS for robust data management and asynchronous communication.
Deployed and managed infrastructure on GKE using Docker and Helm for scalability and reliability.
