A platform used daily by construction professionals

Obat helps construction professionals manage quotes, invoices, projects and teams. PeakLab supports the progressive modernization of its technical foundation while preserving existing workflows and service continuity.

The engagement

Evolve an interconnected system

Understand dependencies between services, data and screens before breaking each change into an independent, integrable scope.

Preserve business rules

Verify that new APIs retain the data, access rights and behavior expected by platform users.

Coordinate several repositories

Plan the integration order across back end and front end so several workstreams can progress with limited conflicts.

A progressive, verifiable migration

Every change starts from the platform’s actual behavior, formalizes the expected contract, and is then validated end to end before integration.

1

Analyze the existing system

Map calls, dependencies and the business rules involved.

2

Define contracts

Explicitly document inputs, outputs and expected errors for the new APIs.

3

Adapt the full chain

Build the back-end services and adapt the related front-end screens and flows.

4

Validate integration

Test journeys, address review feedback and track removal of legacy calls.

Value for Obat

A legacy core that must keep evolving

  • Legacy APIs still used by several screens
  • Dependencies spread across multiple services
  • Regression risk on daily workflows

Controlled modernization

  • Documented and tested interfaces
  • Progressively reduced dependency on the monolith
  • Changes prepared for integration without disruption

What PeakLab puts in place

OpenAPI contracts

Documented interfaces that make shared back-end and front-end expectations explicit.

Specialized business services

A progressive move of responsibilities out of the legacy core, including project resources, team members and retention payments, into more focused services.

Journey validation

Automated and functional tests covering data, permissions and workflows before integration.
