Description

Implement Temporal workflow activities in Go: HSS adapter, PCRF adapter, Inventory update.

Build and validate unit tests for all workflow activities from day one.

Build the Inventory Management Database: tables, indexes, partitioning for 30M records.

Build bulk import tooling: CSV → ICCID/IMSI/MSISDN range ingestion from vendor.

Implement REST API endpoints for Inventory DB (allocate, reserve, release, query SIM records).

Write integration tests: workflow → mock NE → database assertions.

Support Sr. Developer on all workflow development tasks — pair programming expected.

End-to-end test suite: full provisioning flow from SIM activation to order closed.

Load and stress testing: simulate peak TPS provisioning against all systems.

Test automation: CI pipeline integration for all workflow and API tests.

HSS sync integration: IMSI allocation state reflected in HSS (mock → real NE).

MNP (number portability) hooks in Inventory DB.

UAT support: reproduce bugs, write regression tests, validate fixes.
