Your AI test suite is green. Assertions pass. Users are still filing tickets. The gap between testing and evaluation is …
API Security: What Your WAF Can't See
Traditional WAFs cannot protect against broken object-level authorization, your largest API attack surface.
Legacy Monolith Migration: Strangler Fig and CDC
Stop trying to rewrite the monolith all at once. Decouple it incrementally using event streaming.
Serverless Events: Handling Failures, Duplicates, and Partial State
Serverless scaling works. The problems are idempotency, failure recovery, and observability across event chains.
API Integration Patterns: Design for Change
API versioning is not about picking a URL scheme. It is about designing contracts that evolve without breaking …
Backend Latency: The P99 Problem
Average latency is a vanity metric. P99 is where your worst user experiences concentrate, and it compounds geometrically …
Resilience Patterns for Distributed Failures
Distributed systems fail differently than monoliths. Traditional error handling makes things worse. These patterns keep …
Microservice Communication Patterns: REST, gRPC, Events
Choosing between REST, gRPC, and event-driven messaging shapes your entire system's failure domain and coupling model.
Financial Cloud Migration: Zero-Downtime Patterns
Big-bang rewrites fail in finance. The engineering approach for zero-downtime cloud migrations of mission-critical …
Microservice Testing: Covering the Gaps Between Services
The traditional testing pyramid breaks down with 30 independently deployed services.
Disaster Recovery You Can Prove Works
A DR strategy you have never fully failed over under real conditions is not an operational reality.
Chaos Engineering That Finds Real Failures
A single gameday is theater. Real chaos engineering is a systematic program with rigorous prerequisites and continuous …
Event-Driven Architecture: Schema Governance
Spinning up a Kafka cluster is the easy part. Managing schema evolution, data contracts, and consumer failures across …
Legacy API Modernization: Wrap Before You Rewrite
Rewriting legacy APIs from scratch fails more often than it succeeds. The facade pattern lets you modernize …
API Gateway Architecture Done Right
API gateways are routing and auth proxies. Not a dumping ground for data aggregation and complex business rules.
Real-Time Streaming in Production
Treating a streaming pipeline like a fast cron job invites operational chaos. The engineering changes when time becomes …
Service Mesh Adoption: Istio vs Linkerd vs Cilium
Your most expensive engineer just spent two weeks debugging four lines of YAML. That is the real cost of adopting a mesh …
Replacing Legacy Systems Without Stopping Them
Big bang cloud migrations are how critical systems break during cutover. The strangler fig pattern is how you actually …
