Demonstrates how adopting the Functional Reactive Programming (FRP) paradigm and ReactiveCocoa enables composing asynchronous data streams, managing concurrency with RACScheduler, and unifying API parsing with Core Data persistence in a modern iOS app.

The blogpost discusses the development process of the new SoundCloud iOS application, focusing on the implementation of the reactive paradigm.

A Cassandra-backed real-time and batch counting system called Stitch evolves into a Lambda Architecture to provide quick, possibly inexact counts alongside accurate batch totals.

A Cassandra-backed real-time and batch counting system called Stitch combines a fast stream processor with a slower, accurate batch layer in a Lambda Architecture style to keep counts in sync.

SoundCloud's transition from a Rails monolith to a JVM-based microservices ecosystem using Finagle and Scala, detailing language choices, RPC design, and resilience for scalable performance.

SoundCloud's transition from a Rails monolith to JVM-based microservices, adopting Finagle and Scala for a protocol-agnostic, resilient and scalable RPC stack.

Building microservices in Scala and Finagle at SoundCloud

A practical walkthrough of breaking apart a Rails monolith by extracting bounded context features into microservices, using seams and gradual refactoring to minimize risk while preserving continuity.

A concise account of breaking SoundCloud's Rails monolith into loosely coupled microservices by extracting bounded-context features, introducing seams, and avoiding a full refactor.

Enabling teams to build microservices in Scala, Clojure, and JRuby without coupling them

From SoundCloud's monolithic Mothership to a microservices–driven, API-first architecture, this post traces the shift to event-driven messaging, internal and public interfaces, and scalable production workflows.
