Covers the limitations of vibe coding with Claude Code for production-grade work — context window constraints, ad-hoc design, and prompt-as-context friction — and how spec driven development with Kiro addresses them. Walks through Kiro’s three-document workflow (requirements, design, tasks) using a real Cloudflare R2 migration as a worked example. Discusses repository structure, where Kiro…
A walkthrough of migrating a personal blog from Medium to a Hugo-based static site hosted on Cloudflare Pages. Covers the reasons for leaving Medium — ads, poor code highlighting, and Markdown friction — and how the full migration was completed in under 90 minutes.

Three approaches to handling missing JSON properties when unmarshalling into Scala case classes with the Play Framework. Covers Play 2.6’s built-in WithDefaultValues, the Reads.pure() fallback pattern, and a reusable JsonDefaultValueFormatter trait that deep-merges incoming JSON with a default object — useful for large, deeply nested case classes where backward compatibility matters.
Four progressively improved approaches to concurrent programming in Go, demonstrated through a URL health checker. Covers synchronous iteration, goroutines with a naive sleep workaround, WaitGroup-based synchronization from the sync package, and typed channels for structured goroutine communication — illustrating Go’s concurrency model from basic to idiomatic.
Step-by-step tutorial for building a REST API server in Go using the httprouter multiplexer. Covers creating endpoints, structuring the project across multiple files, writing tests with the httptest package, and adding middleware for logging — finishing with a recommended package layout for larger projects.
