Clojure development
Clojure Development for Modern Engineering Teams
Backend platforms, APIs, integrations and data pipelines built in Clojure — designed to be operated and understood by the team that inherits them.

Backend & APIs
HTTP services, internal platforms, event consumers and integrations, with contracts written down and tested.
Data pipelines
Ingestion, transformation and delivery of data with transducers, queues and predictable batching.
ClojureScript
Frontend development and maintenance where ClojureScript is already the right tool for the team.
What we build
Most Clojure development work falls into a few recognizable shapes: an HTTP or gRPC service in front of a database, an event consumer reacting to Kafka or a queue, a scheduled pipeline moving and reshaping data, or an integration layer between systems that were never designed to talk to each other.
The design goal in all of them is the same — keep the data explicit, keep the side effects at the edges, and make the interesting behaviour easy to test without a running cluster. That is what makes a Clojure service pleasant to change eighteen months later.
- HTTP and REST APIs, plus GraphQL where it earns its place
- Event-driven services on Kafka, SQS or similar
- Batch and streaming data pipelines
- Third-party integrations and anti-corruption layers
- Datomic and PostgreSQL data modelling
- Java interoperability inside existing JVM platforms
Engineering practices that come with the code
Delivery is not just merged pull requests. Every piece of work arrives with the things that make it safe to run: tests at the level that actually catches regressions, structured logging, metrics for the paths that matter, and a clear rollback story.
Specs or Malli schemas are used at system boundaries rather than sprinkled everywhere, so validation lives where untrusted data enters. Configuration, secrets and environment differences are handled explicitly instead of by convention.
- REPL-driven development with tests that run in CI
- Schemas and validation at system boundaries
- Structured logs, metrics and traces
- Incremental, reviewable pull requests
- Documentation written for the next engineer
A Clojure development partner, not a body shop
Transducta is a specialized consultancy, not an outsourcing agency with a bench. Engagements are sized so that the work stays deep: a focused scope, direct contact with the engineer doing the work, and honest pushback when a requirement would make the system worse.
If a piece of work is better done by your own team — because the domain knowledge lives there — we will say so and help them do it faster instead.
Frequently asked questions
- Do you build new systems or only work on existing ones?
- Both. New backend services and APIs are built from scratch, and existing production systems are extended and evolved. The second case is more common.
- Do you write ClojureScript as well?
- Yes, where it fits — typically for teams already invested in a ClojureScript frontend or tooling. We will not push ClojureScript onto a team whose frontend is happily TypeScript.
- How do you integrate with our development process?
- Your repository, your branch strategy, your review process and your ticket tracker. Transducta adapts to the team's workflow rather than importing a separate one.
