Hi 👋, I'm Rahul Pal

Full Stack Engineer | Backend Architecture | Multi-Tenant Systems | API Design

👨‍💻 Professional Snapshot

I’m a backend-centric full stack engineer with hands-on experience building scalable, secure, and maintainable systems.

My work typically sits at the intersection of:

  • Business logic
  • System design
  • Real-world constraints (scale, roles, permissions, performance)

I enjoy taking messy requirements and converting them into clean, production-ready architecture.

🧠 What I’m Actively Building & Exploring

  • 🏢 Multi-Tenant SaaS Architecture

    • Schema-based & role-aware access control
    • Tenant isolation, admin/super-admin flows
    • Shared vs tenant-specific resources

  • 🔐 Authentication & Authorization Systems

    • JWT + refresh token lifecycle
    • Role-Based Access Control (RBAC)
    • Token invalidation using jti
    • Secure frontend ↔ backend token flow

  • 💬 Real-Time Systems

    • Chat systems with WebSockets
    • Typing indicators, read receipts, reactions
    • Redis-backed state & performance optimization

  • 📱 Mobile + Backend Integration

    • React Native apps with structured navigation
    • Onboarding flows, loaders, auth-gated routes
    • API stability & backward compatibility

🧩 Core Technical Strengths

Backend & APIs

  • Python: Django, Django REST Framework, FastAPI, Flask
  • RESTful API design & validation
  • Background jobs (Celery)
  • Message queues (Kafka, RabbitMQ)

Databases

  • PostgreSQL (preferred), MySQL
  • MongoDB for flexible schemas
  • Redis for caching, rate limiting, real-time state

Frontend

  • React.js, Next.js
  • TypeScript, Tailwind CSS
  • Clean state & role-based UI rendering

DevOps & Infrastructure

  • AWS (EC2, S3, RDS)
  • Dockerized environments
  • Nginx reverse proxy
  • Environment-driven configuration

🏗️ Engineering Philosophy

  • Design for clarity before cleverness
  • Optimize for readability and long-term maintenance
  • Fail safely, log clearly, recover gracefully
  • Prefer boring, proven solutions in production
  • Think in flows, not just endpoints

📂 Representative Project Themes

  • Multi-role dashboards (Admin / Super-Admin / Employee)
  • Secure token-based authentication systems
  • Tenant-aware chat & notification platforms
  • Backend-first product development
  • Dashboard-driven systems with real business logic
