Projects
Multi-Tenant Task Manager
Architecture Deep DiveA schema-level multi-tenant task management platform built with django-tenants. Each organization gets an isolated PostgreSQL schema with subdomain-based routing, giving complete tenant data isolation while sharing a single Django codebase and deployment.
Stack: Django, django-tenants, PostgreSQL, Subdomain routing, DRF
Real Estate Project Management System
Production SystemA production multi-tenant SaaS for real estate developers. Role-based access control, full audit logging, background processing with Celery, a documented DRF API, and server-side PDF generation for contracts and reports.
Stack: Django, DRF, Celery, RBAC, Audit logs, PDF generation
Knowledge Vault — Multi-Tenant RAG Platform
AI / RAG SystemA domain-agnostic, multi-tenant RAG knowledge platform. The pipeline — PDF ingestion, chunking, embeddings, pgvector search, and citation-grounded answers — works across legal documents, company policies, research papers, compliance manuals, and internal knowledge bases. One reusable AI backend, many industries.
Stack: Django, pgvector, RAG pipeline, OpenAI, Multi-tenant, Embeddings
