Tactical walkthroughs.
The stuff we wish existed when we were stuck at 11pm. Every guide is a reproducible sequence — real code, timestamps, screenshots where they help. No “5 ways to think about…” No listicles. Just the 20 minutes we'd save you.
API Versioning That Doesn't Break Clients (URI + Backward Compatibility Strategy)
Version your API in the URL (/v1/, /v2/). Support multiple versions simultaneously for 12 months. Make changes additive (add fields, don't remove). When you deprecate, give 12-month notice. This prevents the nightmare of breaking 50 integrations.
Build Secure Auth That Doesn't Break (JWT + Refresh Tokens + RBAC)
Use JWT for stateless auth, refresh tokens for long-lived sessions, RBAC for permissions, and HttpOnly cookies instead of localStorage — a pattern that scales to millions of users without auth infrastructure complexity.
Upload Files Directly to S3 (Without Killing Your Server Bandwidth)
Don't proxy file uploads through your server. Generate pre-signed S3 URLs, let users upload directly to S3 — your server stays fast, bandwidth costs drop, and uploads don't block requests.
Build Background Jobs That Actually Run (Bull/BullMQ in Node.js)
Don't handle long tasks in your request handler. Use Bull to queue jobs, process them in the background, retry on failure, and monitor everything — one pattern that fixes 80% of "mysterious" failures in production.

Launchrock vs Unbounce: Which Fits What You're Building
These two tools aren't really competitors — Launchrock validates an idea before you have a product, Unbounce squeezes more conversions out of paid-ad traffic once you have something to sell. A stage-based comparison, not a feature scoreboard.
Launching a SaaS on (Almost) $0/Month: A Category-by-Category Toolkit
A category-by-category toolkit for taking a SaaS from idea to paying customers on near-zero fixed spend — what to prioritize in hosting, database, auth, payments, analytics, email, and more, and the order to add them in.
Run Claude Code on a VPS: The Locked-Down Setup
A server that runs itself, mostly. €5–10/month, ~40 minutes to build — Tailscale for admin access, Cloudflare-only inbound traffic, and Claude Code handling routine administration while you approve what matters.
