Building a Production Multilingual Translation SaaS with Claude API — Glossaries, Style, and Domain Adaptation in Practice
A practical, code-first design guide for running a translation SaaS on Claude API: glossaries, style guides, domain adaptation, quality gates, and cost controls that survive real production traffic.
Building a Production Claude API Pipeline on Cloudflare Queues: Fault Tolerance, Backpressure, and Cost Control
A practical, code-first walkthrough for routing Claude API calls through Cloudflare Queues — covering producer/consumer code, retry-vs-DLQ branching, priority lanes, and token budgeting for production workloads.
Observability for Claude Code with OpenTelemetry — A Production-Grade Tracing Guide for Agentic Workflows
Trace Claude Code agent runs end to end with OpenTelemetry. Hook integration, per-tool spans, MCP propagation, cost attribution, and sampling patterns that survive thousands of runs per day.
Make Claude Your Production Debugging Companion: A Practical Design for Log Triage, Hypothesis Generation, and Repro Scripts
A field-tested blueprint for solo developers who carry their own pager. We split production debugging into three jobs Claude can actually own — log summarization, hypothesis generation, and minimal repro — with full prompts, sanitization code, and traps that cost me real downtime.
Production Semantic Cache for Claude API — Similarity Thresholds, Pollution Defense, and What to Track
A production playbook for adding a semantic cache in front of Claude API — threshold tuning, multi-tenant isolation, pollution prevention, fallbacks, and the metrics that actually prove it works.
Four Infrastructure Levers That Cut Claude API Latency Before You Touch the Model
Before you downgrade Sonnet to Haiku to chase faster responses, the network and request shape around your Claude API calls usually has more headroom. Here are four infrastructure levers — region selection, connection pooling, prompt caching, and streaming — with code and measurement notes.
Claude API × Inngest — Durable AI Workflows with Retries, Idempotency, and Human Approval
A production-grade pattern for combining Claude API with Inngest. Build TypeScript-first durable AI workflows that retry safely, stay idempotent, gate dangerous calls behind human approval, and run on Vercel or Cloudflare Workers.
Managing Claude API Prompts as Code: Registry, Versioning, and A/B Testing in Production
Anyone running Claude API in production eventually hits the same wall: which prompt was served, when, to whom, and at what version? This guide walks through a registry-based architecture with A/B testing, gradual rollouts, and automatic rollback — all implementable yourself in TypeScript.
Production Infrastructure for Claude API — 8 Things You Need Between 'It Works' and 'It Holds Up'
There is a much bigger gap than you'd think between a working Claude API call on your laptop and a service that survives real users. Here are the eight pieces of infrastructure I now consider non-negotiable, learned the hard way.
Claude Code Context Window Mastery — 7 Production Patterns to Stop Sessions From Stalling
Most slowdowns and silent quality drops in Claude Code on large repos come from context window management, not from model limits. This guide walks through seven patterns I rely on in production, with measurement scripts and runtime rules.
Production-Grade Hallucination Defense for Claude API: A Multi-Layer Architecture
Prompt engineering alone is not enough to suppress hallucinations in production. After a real customer incident, I rebuilt the system around four defensive layers — input grounding, tool-use escape hatches, citations, and post-hoc verification. This is the implementation playbook.
Replay-Driven Testing for Claude API: A Production Pattern for Recording and Replaying Responses
A production-grade design for stabilizing Claude API tests by recording and replaying real responses. Covers cassettes for Messages, Streaming, Tool Use, CI integration, and incident replay.
