A distributed, fault-tolerant system with state of art engineering techniques, spanning across multiple DCs in Active-Active mode is an absolute necessity.

Building Distributed systems at this scale is still an Art. While there are standard open-source building blocks available, the right architecture or the way to combine the components needs creativity and deep first-principles understanding.



It also takes wisdom to make the right trade offs combining product/domain expertise with engineering excellence.

At the core, we are an engineering-focused organization with heavy investments in pure functional programming techniques and distributed system architectures. We use Haskell for backend development, we have invested in one of the fastest real-time data streaming technologies, we created our own polyglot database management system called DBMesh.

Some of the current projects in our distributed systems team:
Moving to an LSM engine based distributed DB that spans across datacenter regions
Service mesh architecture that provides failover across Kubernetes clusters
Event sourcing and Event-mesh architecture to move all operations outside the critical path to a reliable async mechanism.
A multi-DC + client-side distributed data caching system and ensuring strong eventual consistency.
Automatic anomaly detection system with streaming data streams across wide-ranging systems
Our teams are mostly built with freshers - smart, vibrant, hardworking. With modern Chaos testing approaches. Check out chaos engineering @ Netflix)
