Two weeks. Three tools. One Next.js codebase I actually ship to users. I'll be upfront: I went in expecting Cursor to win. I've been using it for about eight months and it became my default IDE somewhere around last summer. But my company started rol...
Spent most of last winter doing something I should have done a year earlier: actually reading the TypeScript 5.x changelogs. Not skimming the headlines — reading them, then dropping each feature into a scratch project to see how it actually behaved. ...
About 14 months ago, my team of four migrated our entire backend — a fairly standard Node.js/Python mix serving a B2B SaaS product — fully onto AWS Lambda. We'd read the same blog posts you probably have. Pay for what you use, infinite scale, no serv...
When Redis Ltd announced the license change in March 2024, I was in the middle of planning a caching layer for a mid-sized SaaS product — four engineers, roughly 80k daily active users, nothing hyperscale but enough that infrastructure decisions have...
My team got handed a RAG project earlier this year — 40,000 documents, mix of PDFs and Confluence exports, users who would notice if answers were wrong. I'd used LangChain for smaller stuff before, but this was the first time I actually ran all three...
Eighteen months ago I inherited a mess. A four-person team had built a reasonably capable ML inference service — three Python microservices, a Redis queue, a Postgres instance, an Nginx reverse proxy — all wired together with a docker-compose.yml tha...
I almost picked wrong. We were rebuilding our frontend platform at work — five apps, three shared component libraries, a design token package, and a CLI tool that nobody fully understood anymore. Classic monorepo chaos. I spent about two weeks seriou...
The benchmarks are real. I just didn't expect them to matter less than everything else. My team — four engineers, one of whom is constitutionally allergic to anything not boring and battle-tested — runs a mid-sized API service that handles about 12,0...
The $340 invoice showed up on a Tuesday in late January. Not wild money in isolation, but this was for an internal RAG tool serving exactly 11 people — my team at a fintech startup — and when I did the math, that was $30 per user per month for what a...
