Backend Developer Building Real-World Systems with Node.js, PostgreSQL & Redis
Currently focused on backend engineering through hands-on projects involving authentication, multi-tenant architectures, database design, caching, background job processing, and API development.
Express.js • PostgreSQL • Redis • Authentication • Background Jobs • API Design
Backend Engineering Focus
Areas of backend development I am actively building and studying through hands-on projects.
Built JWT authentication flows, refresh token handling, and role-based access control
Express.js backend development
Worked with schema design, indexing, query optimization, and relational modeling
Performance-focused backend systems
Used Redis for caching, rate limiting, session storage, and background processing
Improving backend performance
APIs
Designed and implemented backend APIs with validation, pagination, and error handling
Production-style backend architecture
Exploring query optimization, caching strategies, and application profiling
Learning performance engineering
Design
Studying scalable backend architectures and distributed system fundamentals
Continuous learning and experimentation
Backend Projects
Personal backend projects focused on authentication, authorization, PostgreSQL, Redis, performance optimization, and scalable API architecture.
Multi-Tenant SaaS Backend
JWT Authentication, RBAC, PostgreSQL & Redis
Focus Area
How can multiple organizations securely share the same backend infrastructure while keeping their data isolated and access controlled?
Implementation
- →JWT authentication with refresh token flow
- →Role-based access control (RBAC)
- →Tenant-aware middleware
- →PostgreSQL schema design
- →Redis caching and rate limiting
- →Input validation and error handling
Background Job Processing Platform
BullMQ, Redis Queues & Worker Architecture
Focus Area
How can long-running tasks be processed reliably without blocking API requests?
Implementation
- →Redis-backed queues using BullMQ
- →Dedicated worker processes
- →Retry and backoff strategies
- →Dead-letter queue exploration
- →Job monitoring and logging
- →Task status tracking APIs
Backend Engineering Philosophy
My approach to building reliable, performant, and maintainable backend systems.
- ✓Structured logging with context
- ✓Distributed tracing across services
- ✓Real-time performance metrics
- ✓Custom business metrics
