Distributed systems · HR product
A predictive HR platform connecting seven Django/DRF services, first-party RS256 identity and a separate TypeScript/Next.js product interface.
01
HR workflows span identity, core records, workload, career, skills, policy and retention. A single coupled application makes those concerns hard to evolve, observe and review independently.

The authentication service issues asymmetric JWTs and a shared package gives every service one verification path without distributing the private key.
Trade-off: The team owns key rotation and authentication operations, but authorization behavior remains inspectable in the same codebase.
Each Django/DRF service owns its PostgreSQL boundary and exposes domain behavior through an API instead of sharing application tables.
Trade-off: Cross-domain workflows require explicit integration and failure handling in exchange for clearer ownership.
The separate Next.js interface includes a clearly labeled backend-free demo mode, while Docker Compose and k3s definitions cover integrated environments.
Trade-off: Demo data improves reviewability but must never be confused with a connected or production environment.
