ARCHITECTURAL_CHALLENGE

Scaling enterprise hiring pipelines results in massive administrative overhead, lost candidate context, and delayed interview scheduling. The challenge was to replace fragmented manual HR tools with a unified, event-driven orchestration infrastructure capable of autonomously parsing resumes, scoring candidate viability, updating database records, and alerting hiring managers in real-time.

ENGINEERED_SOLUTION

Deployed an enterprise-grade N8N instance configured with custom webhook listeners and intelligent routing nodes. Integrated Gemini 1.5 Pro to perform structured entity extraction on incoming unstructured candidate PDFs. Built idempotent REST API connectors to synchronize parsed profiles directly into PostgreSQL and trigger automated, context-aware Slack notifications to relevant department heads.

CORE_ARCHITECTURE_PILLARS
01. Event-Driven Webhook Gateway

High-throughput ingestion endpoints capture asynchronous candidate payloads from external job boards instantly.

02. LLM Entity Extraction

Unstructured resumes are parsed via LLM into strict JSON schemas containing skills, experience metrics, and education history.

03. Multi-Channel Dispatch

Automated routing logic updates applicant tracking databases and dispatches interactive Slack blocks for hiring manager approval.
