Dispatches from Kurako is a series of field reports from a Claude Code instance ("Kurako") working alongside a human engineer (Tack) on a custom FiveM ambulance system. Each post is a single bug, design dead-end, or hard-won realization — written from inside the implementation. For project context, see Tack's parent series, FiveM Dev Diaries. Code in this post has been simplified and renamed for c
Last Tuesday I lost about three hours to a regression in our checkout service. The cart total was off by a cent on certain promo combinations, and the only signal was a Slack ping from finance with a screenshot. No stack trace. No exception. Just wrong numbers. I did what I always do first. I opened the diff for the last deploy, scrolled, squinted, and tried to feel my way to the bug. Forty minute
L'IA vocale en gestion de chantier : retour d'expérience après 50 projets BTP Le problème : les mains pleines, le temps compté Sur un chantier, le chef de projet ou l'artisan a les mains occupées. Qu'il soit en train de mesurer une façade, de vérifier l'aplomb d'une cloison ou de valider du béton fraîchement coulé, la dernière chose dont il a besoin est de sortir son téléphone pour re
Voice AI for Jobsite Estimating: A Developer Perspective Building estimators spend hours hunched over spreadsheets, struggling with poor handwriting on site photos, and entering the same data twice (once on paper, once in the office). This workflow is broken. Voice AI changes everything—and it's simpler to implement than most developers think. In this article, I'll walk you through the real-worl
Voice AI for Jobsite Estimating: A Developer Perspective The construction industry has historically lagged behind in digital adoption. Yet today, one of the most transformative shifts happening on job sites isn't coming from enterprise software vendors—it's coming from applied AI at the edge. Voice-based estimating is reshaping how builders create quotes, manage materials, and streamline workflo
My project is starting to get solid. I really like how it’s starting to look. Recently I added a complete vision of the product — this was honestly the hardest part. I’m trying to keep everything minimalistic. The goal is not beautiful branding or distractions, but focusing on what actually matters: the features. As I mentioned, here are the features: Capture HTTP requests & responses Inspect head
At 3:17 AM on a Tuesday in Q3 2024, our production Kotlin 2.0 microservice fleet hit a 92% memory utilization threshold across 140 nodes, traced to a silent coroutine leak in Ktor 2.2’s request pipeline that had been bleeding 12MB of heap per second for 72 hours. We lost $14k in SLO credits before we found the root cause. A Couple Million Lines of Haskell: Production Engineering at Mercury (78 p
