Delivery experience · Harten operating system

Built in complex estates. Engineered for what comes next.

Harten combines deep founder-led modernisation experience with a unique market offering: Modernisation as a Service, powered by a governed operating system for complex, regulated and service-critical environments.

Persistent context, machine-assisted execution, independent challenge and human decision authority work as one accountable capability from estate evidence to controlled delivery.

Selected delivery highlights

The delivery experience behind the operating system.

These highlights show the shape of work delivered under the founder's leadership across demanding modernisation environments. Client details are anonymised as standard.

Delivery highlight Portfolio-scale transformation

Legacy transformation across large application estates

A repeatable modernisation model combined assisted refactoring, automated test generation and reusable migration patterns across complex applications and interfaces.

Delivery highlight Data integration

A deferred legacy pipeline moved from backlog to a working cloud pattern

Legacy integration packages were converted into tested cloud pipelines, including a particularly complex package. Assisted analysis and controlled validation compressed work that had been expected to span multiple delivery sprints.

Delivery highlight Security and maintainability

Day-one technical debt remediated under a tight delivery window

A large controller was decomposed into bounded services and the authentication and authorisation model was rebuilt, closing an active access-control weakness while improving maintainability and future change safety.

Delivery highlight Architecture decision

Two implementation paths made tangible before a production commitment

Parallel Java and Python prototypes replaced opinion with working evidence for a standards-heavy integration decision. Both paths included tests, logging and documentation, giving decision makers a concrete basis for the next move.

Delivery highlight Framework modernisation

A monolithic internal framework became independently upgradeable packages

Libraries were separated from a legacy .NET Framework dependency and repackaged as independently versioned components, removing a blocker to later runtime upgrades. A reusable migration agent preserved the approach for other teams.

Delivery highlight Language transformation

Transformation patterns established across legacy language families

Assisted refactoring and automated testing established a reusable path from COBOL to Java, with validation and migration guidance designed for repetition beyond the first bounded workload.

Delivery highlight Legacy desktop applications

A desktop database became a reusable web-modernisation blueprint

Legacy forms and embedded logic were reverse engineered into standards-aligned web components and service code, with reusable repositories and openly licensed delivery guidance for future migrations.

Unique market offering

Modernisation as a Service, powered by the Harten operating system.

  • Persistent context: estate evidence, decisions and uncertainty remain connected.
  • Machine-assisted execution: analysis and engineering throughput increase inside explicit controls.
  • Independent challenge: material work is tested and critiqued before approval.
  • Human authority: accountable people own risk, release and the decision to continue or stop.
