YTALとしての開発事例第二弾！！クリーニング業界のパイオニア「白洋舍さん」へのシステム導入事例を公開しました！ クリーニング業法という法律の壁、繁忙期、既存ローコードシステムとの連携という制約が重なるなか、 「2〜3週間でプロトタイプ」 「1ヶ月強でリリース可能な状態」 「3/14 創業120周年に間に合わせて段階リリース」 という感じで、弊社共同代表Taroがやり遂げました！ ✅想定の100倍負荷でも問題なく稼働 ✅アプリ登録率 前年比 +4.9pt ✅年間で数百時間の業務削減見込み ぜひご一読あれ！note.com/ytal/n/n49288b…

Just published our first major development case since incorporating! The requirements were to deeply integrate into an existing system — 1. "demo in 2 weeks", 2. "production in 1 month", 3. "continuous improvement framework in 2 months." We're very confident in this delivery. ✅ 100 hours/month of work time saved (50% reduction in admin tasks) ✅ Achieved without disrupting core development

Pencil MCP and Claude Code Opus 1m token - I think it gives us the power to create something 80% good, 100 times faster. "神は細部に宿る"が、人間がそこに集中できる。

Having less imposter syndrome on CS algorithm stuff; I will spend good chunk of my time going forward trusting LLM with well-scoped problems, with more meta-guardrails in place.

Given the concept of philschmid.de/context-engine… -- context engineering to enable LLM based coding -- what are your favorite tooling right now?

Convex は Claude Codeととても仲良し。あと、Claude Codeは "1 file, 1 function" で pureな関数を書かせるととても良い子になるし、Input/Outputの型定義が良いほど一発で正解出してくれる。

Convex.dev works great with Claude Code; also Claude Code hallucinates least when instructed to create a "pure" function (one function, one file manner) with strictly typed inputs and outputs (prob. obvious for some of you, but)

Wrote a tech article! zenn.dev/kenzan100/arti… hope you like it :)

Does anybody know when/if ppl who submitted proposals for #RubyKaigi2024 LT will receive accepted / rejected status update?

@billfranklinuk so we're kind of bottom on job posts / job seeker ratio 😢

I've submitted a CFP for RubyKaigi 2024 (LT track) Creating data-intensive web application framework in Ruby In this talk, I will explore a concept for building data-intensive applications using Ruby, emphasizing the convention over configuration approach popularized by Rails..

Happy New Year! I've listed a bunch of things I've done in the past 3 months, like upgrading Ruby, introducing Sorbet, and retiring one of the badly (sorry) architected services.. Send me a msg if you happen to have one of these issues at your workplaces :) happy to help!

Wrote "How I work", inspired by some of the folks I've met during Shopify period :)
