Tech @ Exotel
Exotel Engineering solves some really cool infrastructure-level problems with the goal of ensuring no one misses a call or an SMS.
Our focus is on building a very fault-tolerant, loosely coupled, scalable and real-time distributed system
We are generally agnostic of language, technology or tools. Currently, our tech stack is built on Golang, Node.js, Ruby, Java and PHP. We use Aerospike, MySQL as data stores, ElasticSearch for search and Beanstalkd for queuing
We emphasize a lot on clean abstractions of code, loosely coupled services and good coding practices
We are very strong believers in you built it, you own it!. And running a distributed system is very different from just building one!
We are crazy about high availability
