Data-Intensive Backend Services
We build scalable and resilient backend systems designed to process, transform, and serve data with exceptional clarity. Using Clojure’s immutable data structures and powerful concurrency models, we develop high-throughput APIs and data processing pipelines that are easy to reason about and incredibly stable. Our solutions provide a simple, powerful core for your most complex data challenges.
Interactive Web Applications (ClojureScript)
Our developers create rich, interactive frontend applications using ClojureScript with modern frameworks like Reagent and re-frame. By embracing a functional, data-driven approach, we manage complex UI state with unparalleled simplicity. The result is a highly maintainable and performant web application that is less prone to bugs and a joy for your team to extend.
Data Engineering & Big Data Pipelines
Our team leverages Clojure's data-first philosophy and seamless Java interop to build sophisticated data engineering pipelines. We design systems that integrate with platforms like Kafka, Spark, and Flink to handle large-scale data ingestion and transformation. Clojure's expressive power makes it the ideal tool for manipulating complex datasets with precision and efficiency.
Financial Services & Trading Systems
We build robust, high-precision systems for the financial industry, where correctness and reliability are non-negotiable. Clojure's strengths in managing state and its predictable, functional nature make it perfect for creating trading engines, risk analysis platforms, and ledger systems. We deliver solutions that provide stability and auditability in mission-critical environments.
Rapid Prototyping and Internal Tooling
We harness Clojure’s REPL-driven, dynamic development to build custom tools and prototypes at high velocity. This interactive workflow allows us to iterate rapidly on business logic, build powerful domain-specific languages (DSLs), and deliver functional software in a fraction of the time, providing immediate value and feedback for your business.

Latest Trends in Clojure Development
Native Binaries with GraalVM
A major trend is the adoption of GraalVM to compile Clojure applications into lightning-fast, native executables. This eliminates JVM startup time and reduces memory footprint, making Clojure a first-class citizen for serverless functions, command-line tools, and fast-booting microservices.
The Rise of Immutable Databases
There is a growing movement towards using immutable, temporal databases like Datomic and Crux. These databases align perfectly with Clojure's data-driven philosophy, simplifying application state and providing powerful capabilities to query data as it existed at any point in time.
Data Science and ML with tech.ml.dataset
Clojure is seeing a significant trend in data science, powered by libraries like tech.ml.dataset. This allows teams to leverage Clojure's data manipulation prowess for high-performance data analysis and machine learning, all while staying within a single, cohesive language and ecosystem.
Hyper-Interactive UIs with ClojureScript
The ClojureScript ecosystem continues to push the boundaries of frontend development. The trend is toward building highly interactive, data-driven user interfaces that are defined declaratively, making complex application states manageable and predictable, even as features grow.
REPL-Driven Development as a Superpower
Rather than a new feature, the trend is a deeper appreciation and leveraging of Clojure’s core strength: interactive, REPL-driven development. Teams are building systems designed to be developed, inspected, and even modified live, leading to an incredibly tight and productive feedback loop.
Our Success Stories
Simplifying a Core Data Platform for an Analytics Leader
A leading market intelligence firm needed to re-architect its complex and brittle data ingestion platform to handle increasing volume and variety.
The resulting Clojure-based system simplified the architecture by 70%, improved data throughput by 2x, and enabled new features to be added in days instead of months.
Building a Real-Time Reporting UI for a Global Bank
A major financial institution required a new frontend for its risk management dashboard that could handle real-time data streams without freezing or crashing.
Entrans delivered a ClojureScript and re-frame application that provided a fluid, real-time user experience and reduced UI-related bugs by over 95%.
FAQs on Hiring Clojure Developers
A Clojure developer builds applications by composing simple functions and operating on immutable data. They typically specialize in data-intensive backend services, data engineering pipelines, and complex, interactive web applications using ClojureScript. Their work emphasizes clarity, correctness, and simplicity.
They use a build tool like Leiningen or the Clojure CLI, and a powerful text editor connected to a REPL (Read-Eval-Print Loop). Key libraries include Ring/Pedestal for backends and Reagent/re-frame for frontends. The REPL is the most essential tool, allowing for unmatched interactive development.
Clojure applications are typically packaged as an executable JAR file and run on the Java Virtual Machine (JVM), often within a Docker container. ClojureScript applications are compiled into a JavaScript file for deployment on any web server or CDN. Increasingly, they are also compiled to native binaries using GraalVM.
