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.
-
🏢 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
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
- 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
- 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
