▸ Architected HireBoard, an enterprise-grade recruitment REST API supporting full candidate lifecycle
management — from profile creation and application tracking to multi-client profile matching — serving
multiple concurrent tenant clients.
▸ Implemented JWT-based stateless authentication and session isolation, enforcing strict identity boundary
separation across candidate profiles and preventing unauthorized cross-tenant data access.
▸ Enforced server-side request validation via Zod schema contracts on all public endpoints, eliminating
malformed input, injection vectors, and type-mismatch vulnerabilities before data reached business logic
layers.
▸ Optimized multi-tier database query pipelines for complex filtered searches across large candidate datasets,
reducing processing latency and improving throughput on high-cardinality sort operations.
