Expertise
Languages do matter, but so does everything else. Boundaries, data, tests, deployments and production behaviour. See where Hypnoshroom can help across the stack.
Languages
The language sets the context. The real work is making the system safer to change, easier to operate and clearer for the team to own.
Core specialism
Scala is often chosen for long-lived JVM services where complex domains, concurrency and correctness matter. It is our core specialism across Play Framework, functional Scala, sbt and production backend systems.
Backend engineering
Java powers long-lived business platforms, APIs and backend services where stability, JVM performance and strong tooling matter. We help teams keep those systems reliable and easier to change.
Frontend and Modern applications
TypeScript brings stronger tooling and compile-time feedback to modern web products. We use it with Nuxt and Vue for SaaS applications, server-side or client-side rendering, APIs and full-stack features.
Services & automation
Python’s approachable syntax and broad ecosystem make it a strong fit for scripting, automation, APIs and AI integrations. We help turn those workflows into maintainable software with clear boundaries and reliable tests.
Databases
Database design and application design belong together. Schemas, documents, queries, indexes and persistence code are considered as one working boundary.
Relational data
Schemas, normalisation, indexes, queries and migrations—alongside the persistence code responsible for keeping relational constraints clear.
Document data
Document shapes, indexes and query patterns designed around how the service reads, changes and owns its data.
Testing & quality
A healthy test strategy is not a race for coverage. It should give quick feedback close to the code and stronger evidence at the boundaries that matter.
ScalaTest · JUnit · Mockito · frontend component tests
Fast tests that explain behaviour clearly and make ordinary changes safer to ship.
APIs · databases · queues · third-party boundaries
Tests around the joins where otherwise-correct components tend to disagree in production.
Cucumber · Selenium · Playwright
A small number of valuable journeys, backed by reliable test data and a delivery pipeline that makes failures useful.
DevOps & platform engineering
Builds, pipelines, deployments and observability should help teams ship with confidence and understand what happens after release.
