Microservices Design Patterns: Building Distributed Systems That Work
Patterns that keep microservices maintainable: API gateway, circuit breaker, saga, database-per-service and event-driven boundaries.
Writing
Notes on architecture
System design, event-driven architecture, cloud-native delivery and applied AI — written from enterprise practice by Sanjeev Kumar — Application Architect.
Designing for User Experience: Beyond Pretty Interfaces
UX as product architecture: research, information architecture and flows that reduce friction in real enterprise tools.
React Performance Optimization: Real-World Techniques That Work
Production React performance: render model, memoization, code splitting and measuring what actually moves the needle.
System Architecture Best Practices: Building Maintainable Software
Architecture practices that keep systems changeable: separation of concerns, boundaries, evolutionary design and operational feedback.
Cloud Architecture Patterns: Building Scalable Systems on AWS, Azure, and GCP
Cloud-native patterns I use on AWS, Azure and GCP: serverless boundaries, containers, autoscaling, multi-cloud tradeoffs and cost control.
Building Scalable Web Applications: Lessons from 12+ Years in Production
Production-tested scaling decisions: database bottlenecks, caching, horizontal growth, and when microservices help versus hurt.
