The Problem
A tightly coupled monolithic platform made it impossible to release new capabilities without coordinating across all teams. Audit trails were incomplete and unreliable. Regulatory compliance required immutable event logs that the current architecture couldn't produce.
My Contribution
I mapped the current-state data flows across the monolithic platform, documented every inter-service dependency, and led workshops with each domain team to define their data ownership boundaries and integration contracts. I authored data mapping specifications for each of the 12 service domains, worked with the compliance team to ensure audit trail requirements were built into the data schema design from the start, and managed stakeholder sign-off across six product teams before migration began. I also coordinated with R&D and DevOps teams to translate business data requirements into technical implementation guidance.
The Solution
Requirements-led decoupling: current-state dependency mapping, domain boundary definition workshops, data mapping documentation for each service, compliance audit trail specifications, and staged stakeholder sign-off across all affected teams.
Results
- 12 service domains now evolve independently
- 100% complete compliance audit trail
- Zero data loss across all integration streams
- 60% faster incident diagnosis via traceable data lineage
Defining data ownership before drawing service boundaries was the decision that prevented the most conflict. Every team disagreement during the migration traced back to unclear ownership of a shared data entity — resolving those in requirements workshops rather than in sprint planning saved weeks of rework.
