Reliable employee data. Controlled changes.
An HR lifecycle integration built around identity, exceptions, and verification.
At a glance
The problem
Employee lifecycle changes needed to move reliably between HR and performance systems. File-based handoffs and mismatched identities created correction work and operational risk.
My role
I led the integration work: lifecycle routing, identity matching, source write-backs, exception handling, test design, controlled correction waves, and destination verification.
Decisions that mattered
- 01Treat create, update, deactivate, and reactivate as distinct paths with explicit matching rules.
- 02Test a small canary before expanding a change; define rollback and exception ownership before execution.
- 03Read the destination API after a change. A successful request alone is not proof of the intended record state.
What changed
Delivered the core production sync and verified corrections across hundreds of employee records. Correction cohorts overlap and are not added together.
Walkthrough
A fictional employee record arrives with a department change.
Follow one employee change.
What this establishes
This describes delivered capability and verified corrections, not quantified labor savings or a claim that every reconciliation exception was closed.
What I would measure next
Measure correction frequency, exception aging, and handling time against a pre-change baseline.
