JDK and framework upgrade
Bringing an application onto a current long-term-support JDK and Spring release, resolving deprecated APIs and dependency conflicts along the way.
Java development
Dependable Java systems, new and long-lived
We build new services, modernize older applications and fix the performance and maintainability problems that slow your team down, using current Java and Spring practices.
What we do
Back-end engineering, end to end
- Enterprise application development Business applications and back-end services designed for clarity, testability and the long life most enterprise software ends up having.
- Spring Boot microservices Well-bounded services with clean APIs, sensible data ownership, observability and containerized deployment, without splitting things up further than you need.
- Modernization and migration Moving legacy Java EE applications, older Spring versions and outdated JDKs onto supported platforms, incrementally and with tests guarding behavior along the way.
- Performance tuning Profiling, query and connection-pool tuning, JVM and garbage collection settings, and caching, guided by measurements from your actual workload.
- Code review and architecture An independent look at your codebase and design, with specific, prioritized recommendations your team can act on.
Typical engagements
Common ways we help
Incremental modernization
Carving well-defined pieces out of a monolith or legacy platform one at a time, so the business keeps running while the system improves.
Performance investigation
Finding the real cause of slow responses, memory pressure or instability, fixing it, and leaving you with the monitoring to catch it next time.
How we approach it
Small, safe steps on working software
-
Read the code first
We understand what the system does today, including the undocumented parts, before proposing changes to it.
-
Build a safety net
Automated tests and a reliable build pipeline come early, so every later change can be made with confidence.
-
Change incrementally
Frequent, reviewable releases instead of a risky big-bang rewrite, with your engineers involved throughout.
