New Systems and APIs
New Java services, APIs, and backend applications.
We design and deliver Java services, REST and event driven APIs, backend applications, domain components, and internal platforms. Our agents accelerate scaffolding, bounded implementation, and test coverage, working from a client specific context layer built over your repositories and exposed to our agents through MCP, so they work from verified information rather than guessing. The principal architect owns the architecture, the security judgment, and review of every change that ships.
What the work includes
- Service design: service boundaries, contracts, and data ownership defined before implementation starts.
- API delivery: REST and event driven endpoints built on Spring, with validation, error handling, and documented contracts.
- Domain components: bounded business logic delivered as reviewed, tested production code.
- Internal platforms: shared libraries and internal services that other work builds on.
Typical stack
Java 21 · Spring Boot · REST · Kafka · PostgreSQL · Docker
Java and Spring Upgrades
Java, Spring, dependency, and build system upgrades.
We upgrade Java, Spring, dependencies, and build systems, sequencing changes around real architectural constraints rather than around what the tooling finds first. Our agents accelerate the mechanical work such as dependency updates, namespace migrations, and test runs across modules. The principal architect owns the sequencing, the risk decisions, and review of every change before it merges.
What the work includes
- Runtime upgrades: moves across Java versions with behavioural changes identified, tested, and documented.
- Spring migrations: Boot and Framework major version moves, including the Jakarta namespace transition.
- Dependency remediation: vulnerable and abandoned libraries updated or replaced with supported successors.
- Build system work: Maven and Gradle upgrades, plugin migrations, and reproducible builds.
Typical stack
Java 8 to 21 · Spring Boot 2.x · Spring Framework 6 · Jakarta · Maven / Gradle
Legacy Modernization
Application server exits and monolith decomposition.
We run application server exits, monolith decomposition, dependency remediation, and replacement of aging components. Our agents accelerate code analysis, mechanical refactoring, and test scaffolding across large codebases. The principal architect owns the decomposition strategy, the cutover plan, and the production readiness decision.
What the work includes
- Application server exits: workloads moved off WebLogic, WebSphere, and JBoss onto supported runtimes.
- Monolith decomposition: components extracted along real seams, one bounded piece at a time.
- Component replacement: aging services and libraries replaced with tested, reviewed successors.
- End of life exposure: dependencies past their support window remediated before they become incidents.
Typical stack
Java 8 · Spring Framework 4 / 5 · WebLogic / WebSphere · JBoss · Oracle · MS SQL Server
Integration and Data Flows
Connecting applications, vendors, events, and data.
We connect applications, services, vendors, events, and data sources through maintainable Java integration patterns. Our agents accelerate connector implementation, mapping code, and integration tests. The principal architect owns the integration design, the failure handling decisions, and review of what ships.
What the work includes
- Service integration: internal applications and services connected through documented, versioned contracts.
- Vendor connections: third party systems integrated behind interfaces your codebase controls.
- Event flows: topics, producers, and consumers with explicit schemas and replay behaviour considered up front.
- Data movement: batch and streaming paths between data sources, built as tested Java code.
Typical stack
REST · Kafka · Solace · Spring Batch · PostgreSQL · MS SQL Server
AWS Delivery
Java systems architected, deployed, and operated on AWS.
We architect, containerize, deploy, and operate Java systems with appropriate AWS services, IAM, and production safeguards. Our agents accelerate infrastructure definitions, deployment configuration, and operational scaffolding. The principal architect owns the AWS architecture, the IAM and security judgment, and the production readiness call.
What the work includes
- Architecture: AWS services selected to fit the workload, with the tradeoffs written down.
- Containerization: Java services packaged for ECS or EKS with sensible resource and runtime settings.
- IAM and safeguards: least privilege roles, network boundaries, and controlled deployment paths.
- Operations: logging, alarms, and runbooks so the system can be operated by the people who own it.
Typical stack
ECS / EKS · IAM · S3 · Docker · OpenTelemetry
Build, Release, and CI/CD
The pipeline work required to ship Java changes safely.
We deliver the build automation, release pipelines, containerization, and deployment work required to ship Java changes safely. Our agents accelerate pipeline configuration, build scripts, and repetitive migration work. The principal architect owns the release design, the rollback approach, and the decision on what is safe to automate.
What the work includes
- Build automation: Maven and Gradle builds that are reproducible and understood by the people who inherit them.
- Release pipelines: CI/CD stages with tests, checks, and approvals in the places they belong.
- Containerization: images built consistently, scanned, and versioned alongside the code.
- Deployment work: rolling deployments, configuration management, and rehearsed rollback.
Typical stack
Maven / Gradle · Docker · JUnit · Testcontainers · ECS
Reliability and Performance
Testing, diagnostics, and operational readiness.
We work on automated testing, production stability, diagnostics, observability, throughput, latency, and operational readiness. Our agents accelerate test authoring, instrumentation, and defect reproduction. The principal architect owns the diagnosis, the performance judgment, and the readiness assessment.
What the work includes
- Automated testing: unit, integration, and regression coverage added where it protects real behaviour.
- Diagnostics and observability: metrics, tracing, and logging that answer questions during an incident.
- Throughput and latency: performance investigation grounded in measurement, with changes tested before rollout.
Typical stack
JUnit · Testcontainers · OpenTelemetry · Grafana · JVM tuning
Engineering Automation and Backlog
Bounded technical backlog items, completed and reviewed.
We reduce repetitive engineering work, remediate dependencies, improve documentation, address defects, and complete bounded technical backlog items. Our agents execute the repetitive portion as parallel bounded workstreams. The principal architect scopes each item, reviews the changes, and decides what merges.
What the work includes
- Repetitive engineering work: mechanical changes applied consistently across modules and repositories.
- Defects and documentation: reported defects addressed and documentation brought back in line with the code.
- Bounded backlog items: individually scoped, individually reviewed, and closed with delivery evidence.
Typical stack
Java · Spring · Maven / Gradle · JUnit · Jakarta
