🏗️ What I've Built

🔐 Centralized Identity Provider OAuth 2.0 + OIDC compliant IdP for 5 products JWT with EdDSA signing · PKCE for public clients Refresh token families with cascade revocation Per-product token isolation & subscription-based auth 29 endpoints · Auth, Session, OIDC, Audit routers FastAPI + Tortoise ORM + asyncpg + Redis + Taskiq	📊 ETL Pipeline Architecture End-to-end data processing from scratch Airflow orchestration + PySpark transforms 200K+ recruitment records processed Idempotent design — safe re-execution guaranteed PostgreSQL + pgvector for semantic search Schema-inconsistency handling across sources
🕷️ Distributed Web Scraping High-throughput scraping infrastructure Source-specific worker pools (LinkedIn, Naukri) Redis/Celery task distribution Planned Kubernetes + KEDA autoscaling Rate limiting & anti-detection strategies	🔍 Open Source — Typesense #2638 Diagnosed critical issue in 25K+ ⭐ project Raft consensus thread starvation · 228K bulk inserts Write queue blocking /health & /search APIs Proposed decoupled health endpoints + backpressure Systems-level debugging at consensus layer

🔐 Architecture — Identity Provider

💎 Open Source

Issue #2638 — Diagnosed Raft consensus thread starvation during 228K document bulk inserts. Proposed decoupled health endpoints and configurable write backpressure.
