Huge thanks to meet.js for having me at the Summit — the heart of Poland's JS community since 2011 — for my first-ever large-stage talk. Terrifying, and one of the best things I've done as an engineer. Recording's up! 👇 www.youtube.com/watch?v=mfCM...

For the first time in five years, my cholesterol levels are back in the normal range. Best news this year.

in my experience, AI is excelling at most technical work except for ”what is the right next problem to work on”. for now, humans still have a noticeable advantage there

We have access to nearly unlimited intelligence, yet we choose to spend our time scrolling through social media.

This is how moving from heavy Fable use to trying Opus 5.5 feels like for my token spend.

I used the Codex Desktop App all day today after having only used the Claude Code for the past six months or so and oh boy I’ve been missing nice-looking UIs. 🤤

📢 I'm officially looking for a new job. You hiring? Full time, remote from Spain, paid via EOR, IC, TypeScript, no crypto, support for 3-4 conference speaking gigs/year. Share plz. 🙏 DMs open.

Daddy, draw an elephant.

/goal write tests @kentcdodds.com would be proud of.

No idea what just happened but got 16 new friends today on this platform. Hello everyone! 👋

Personal website maintenance day.

I've chatted with a few friends lately about the work we're doing at the moment. It's a fantastic way to spark new ideas for articles. Added two new topics to the list. ✍️

TIL: @tanstack.com has a hotkeys library. 🔥 tanstack.com/hotkeys/latest

A weird urge to read some fiction. I think for the past 10 years or so I only read non-fiction books. Any recommendations?

Me: closing my laptop on Friday before two weeks off Anthropic: drops a new model

I haven't missed a workout in two months. Feels really good.

This week, I did my first ever user research interviews—giving people a prototype of a feature and watching them try to use it. It's fascinating how differently people use software, yet they still run into many of the same problems.

Turns out, I’m going to be building a Figma-style editor next week. Good that Fable is back, just in time.

Me on the other side of this weekend (peak temperature: 40⁰C).

I think I'm old enough now to get a walking pad. 🫣 Anyone has recommendations? Looking for something to put under my desk, for walking only.

A year ago, building a custom tool for one library upgrade would've been a waste of time. With agents, the math flips. Things not worth building before are suddenly worth it: run once, then delete. I walk through one I built for a React Query migration. blog.tomaszgil.me/throwaway-by...

Astro 7 is here! A new Rust compiler, a new Rust Markdown/MDX processor, Vite 8 and more. Get ready for 60%+ faster builds. astro.build/blog/astro-7/

The best software I’ve written has always been software I was a user of. Using it every day made the rough edges impossible to ignore.

The number of sessions I managed to have with Fable before the shutdown: 1. 🤐

Final post in the Offline Support for Web Apps series. 📴 Image bytes don't belong in your app state. This one is about splitting the data layer — data in one place, image bytes in another — and letting a service worker handle the transport. More in the article. blog.tomaszgil.me/offline-supp...

Hear me out: self-healing codebases. 👀 Periodically feed the agent all rules and architecture docs and let it apply "safe" fixes.

I've been moving off of Cursor, to Claude Code. Man, it's slow. 🥱

New post in Offline Support for Web Apps series. 📴 Prefetching can make offline UX feel seamless — or completely tank performance. This one breaks down how to do it carefully: when, what, and how much. More in the article. blog.tomaszgil.me/offline-supp...

I'm switching away from Cursor, diving into Claude Code. 👀 What is your preferred way of interacting with it? I'm specifically interested in something for managing your conversations within and across projects.

Days since I used `useImperativeHandle` in React: 0.

Today: trying out Ralph. 🤖

TypeScript 6.0 is now available! This release brings better type-checking for methods, new standard library features, new module features for Node.js, and more! But most important, this release brings us one step closer to the upcoming native-speed 7.0! devblogs.microsoft.com/typescript/a...

📚 Continuing my series about design-systems, today I wrote about why I believe data-testid is a bad practice and and how role-based selectors actually help ensure your app is accessible.

I’ve stopped writing code by hand. I hesitated to post this because it already feels obsolete — my workflow is evolving as I write this. Still, I break down how I currently work with AI agents end-to-end. More in the article. blog.tomaszgil.me/the-agent-fi...

AI promised me I’d finally have time to post unhinged memes on social media. Now I’m just doing more work and endlessly tweaking my workflow. Send help.

Roughly two weeks ago I drafted a post about how I use AI in my workflow, reflecting on the last 6 months or so. It already feels obsolete. I wonder if I should even post it. 🙈

New post in the Offline Support for Web Apps series. 📴 This one moves from queue implementation to real application usage — wiring the queue into React, capturing offline mutations, and syncing them safely later. More in the article. blog.tomaszgil.me/offline-supp...

Being good at context switching becomes a lot more important when you have multiple agents running simultaneously on different things. In my experience, most devs prefer focused work and being “in the zone”. I feel this is gonna be a big adjustment and why many are still sceptical. It’s hard.

i really don't care about using AI to ship more stuff it's really hard to come up with stuff worth shipping i want to ship the same amount of stuff with higher quality both in product and code

Just finished speaking at meet.js Summit 2026 about Shipping Offline Support on the Web. 🎤 It was my first time presenting at a conference of this scale — and what an experience. Huge thanks to the organizers. Appreciate the engaged audience, sharp questions and conversations afterward. 🙏

There's no legitimate reason to "write code by hand" anymore.

I didn't realise how or when it happened exactly, but after almost 10 years in the industry, I have a small network of people I can rely on, discuss things and ask for help. It's incredibly valuable. I'm really grateful for that.

Slides ready. Excited for next week. 👀
