Writing about Distributed Systems
Thoughts, deep-dives, and architectural blueprints on building scalable backends, cloud infrastructure, and secure APIs. No basic tutorials—just production-grade engineering.
Featured Blueprint
Building AI-Powered Document Extraction Pipelines
How we replaced filename-based classification with deterministic content-based analysis using Vertex AI, OCR fallback, and SQS event sourcing.
JWT Authentication Is Not Enough
Security practices every backend should implement: refresh token rotation, robust RBAC, session revocation, and audit logging.
Designing Secure File Upload Systems on AWS
Implementing virus scanning, pre-signed URLs, strict bucket policies, and MIME validation to prevent malicious payloads in S3.
Building Event-Driven Systems with Lambda, SQS & EventBridge
Why synchronous APIs don't scale. A deep dive into decoupling services, dead-letter queues (DLQ), idempotency, and retry strategies.
20 Backend Security Mistakes Developers Still Make
From trusting frontend validation to open S3 buckets and missing rate limiters—avoiding catastrophic vulnerabilities in production.
Designing APIs That Survive Production Traffic
Strict API contracts, pagination, rate limiting, and defensive validation to ensure your services don't buckle under load.
IAM Best Practices Every Developer Ignores
Enforcing least privilege, using STS for temporary credentials, and properly scoping resource policies to secure your cloud infrastructure.
How We Reduced Backend Response Time by 50%
Optimizing queries, implementing Redis connection pooling, cache invalidation strategies, and dropping latency to P99 ~12ms.
Designing Scalable Notification Systems
Architecting a real-time WebSocket notification service with Redis Pub/Sub, fan-out queues, and offline user recovery.
Production Incidents That Changed How I Build Software
Hard-earned lessons on logging, distributed tracing, circuit breakers, and why you should always expect network failures.
