Using AI to Debug Production Issues: Claude, ChatGPT, and Error Analysis
AI-assisted debugging can cut production MTTR by 60–80% when used correctly. Learn how to prompt Claude and ChatGPT for root cause hypotheses, verify against real signals, and build a repeatable incident workflow.
Fix CORS Errors in Production: The Complete 2026 Guide
CORS works on localhost but breaks in production. Decode the six most common browser errors, configure Express, Next.js, Django, FastAPI, and Nginx correctly, handle OPTIONS preflight, avoid wildcard + credentials traps, and ship with a production checklist.
The API-First Architecture: Why Modern Apps Start with the Database, Not the Frontend
Most teams build UI first and bolt on an API—then mobile, partners, and AI agents pay the price. API-first flips the order: model data and constraints in the database, define the contract (OpenAPI, GraphQL, tRPC), then implement. Here is why that scales, how REST/GraphQL/tRPC fit together, and a practical adoption path with citations.
Understanding Cloud Infrastructure Pricing: Why Your $50/Month App Costs $500 in Production
Cloud pricing calculators show compute and databases, but production bills include egress, NAT gateways, IPv4 fees, cross-AZ transfer, load balancer processing, and observability. Here’s how a $50/month estimate becomes $500+—and how to save 40–70% without breaking reliability.
