The REST APIs and workflows behind Peoplebox's core HR modules — one service layer powering six product areas.
Peoplebox's core is a set of HR workflows — goals, performance reviews, surveys — each with its own state machine, permissions, and audit trail, used by enterprise orgs at scale.
New modules kept re-solving the same problems — auth, permissions, job queues — and inconsistent patterns were slow to extend and hard to trust.
Standardised REST contracts and ActiveRecord models so every module shares one contract.
Moved long-running work to Sidekiq so responses stay fast and retries are safe.
Designed schemas first — migrations and indexes as the contract, code second.
Turned production incidents into refactors, not patches, so reliability compounds.
The schema is the contract. When the data model is right, the API, the queue, and the permissions all fall out of it.

Goals, Reviews, Surveys, HRIS, IDPs, and reporting on one service layer
RAG-grounded LLM workflows that answer enterprise questions from real company knowledge — not a demo corpus.
100% grounded — every answer traced to a retrieved source — never generated from memory
EXPLAIN-first schema and query work that kept enterprise dashboards and workflows fast as data grew.
p95 response time — flattened on million-row tables by index-backed, EXPLAIN-first query plans
The reliability layer that keeps employee and identity data in sync across customers' HRIS and identity systems.
24/7 in sync — employee and identity data flowing reliably across customer systems
