Status update: wife's sick, kid's sick, I'm still holding on.

My first ever CFP submission just went through. I guess I have a month to prepare a talk now. 🤐

New post in the Offline Support for Web Apps series. 📴 This one moves into the UI layer: exposing queue state, subscribing to updates, and wiring a single long-lived foreground queue into React. More in the article. blog.tomaszgil.me/offline-supp...

"For you" feed has become quite usable for me recently. 👀

Trying to avoid getting sick when half of your kid's daycare has flu.

Moltbook, reddit-like forum, where agents talk with other agents (mostly using Opus 4.5 with Claude Code via OpenClaw). This is something else. Enter at your own peril. www.moltbook.com/post/34809c7...

I never really understood the phenomenon of tools like Claude Code or Codex CLI and the fact that they run in a terminal. Terminal is the wrong place for UIs like that. It's almost like trying to have a full editor experience in a terminal... Oh, wait.

Once, my friend asked me if by teaching others I'm not creating competition for myself. I get where he was coming from, but that's not how I see it. We aren't in a race, we are in a life-long hackathon. If someone levels up, everyone wins. And I win, too.

Approx. 90% of the code I ship is written by agents, yet I still don't really know what MCPs are. AMA.

Small tweaks in how you use LLMs can save a lot of tokens. Here are 3 steps that worked well for me in practice. 👇

New post in Offline Support for Web Apps series. 📴 This one dives into the hard parts of a foreground queue: atomic read–modify–write, enqueue-time deduplication & bounds, and a single-flight sync loop you can safely pause. More in the article. blog.tomaszgil.me/offline-supp...

Hot take: if your company does not allow engineers to use Cursor or Claude Code, they're actively hurting your career. (no, Copilot doesn't count)

Now that AI writes most of my code, I think I should get back to posting more memes.

“This is a small codebase, there can’t be much dead code”… Added knip.dev. Deleted ~800 lines immediately. Yeah. Absolute no-brainer. Incredible value. 👏 @webpro.nl

New post in Offline Support for Web Apps series. 📴 Offline writes are the hard part of offline support. I wrote about using a foreground queue to make offline mutations explicit, durable, and predictable. More in the article. blog.tomaszgil.me/offline-supp...

One of the best decisions I’ve made in my life was going off Instagram/Facebook/TikTok a few years ago.

em dash is my second most frequently used emoji, I’ll be forever suspected to be a robot.

Receiving "changes requested" on your pull request.

If you write a prompt, and it obviously sucks — ask AI to turn it into a better prompt and refine from there. Works like a charm. That's the moment you realise AI is better even at writing prompts. 🙃

New post in Offline Support for Web Apps series. 📴 Offline support starts long before background sync or queues. The real foundation is data persistence. In this post, I break down how to do this with React Query and IndexedDB. More in the article. blog.tomaszgil.me/offline-supp...

Hey web tech nerd friends, I'm organizing a by-community for-charity conference on March4. Who wants to speak? Sharing CFP privately to frontload the submissions from humans 😅 Respond and I'll DM a link

Late Christmas present: my copy of Scaling Fast by @swizec.com just got delivered. 📦

In 2026, your impact as a software engineer will be directly related to how fast and how well you can *review* code.

When AI writes almost all code, what happens to software engineering? @gergely.pragmaticengineer.com open.substack.com/pub/pragmati...

Rafał is one of the best engineers I worked with — he has a lot to share, give him a follow! 👇

New post in Offline support for Web Apps series. 📴 If your app can’t even reload without a network, nothing else matters. In this post, I break down the minimal baseline for offline support: making the app shell load offline. More in the article. blog.tomaszgil.me/offline-supp...

Short 2025 summary. 🎉 Joined OpenSpace as a Senior Software Engineer 🚀 Released an updated version of tomaszgil.me 📃 Wrote 5 articles 👀 Got 5k+ blog views (32k+ in total) Looking forward to 2026! 🎆

📚 New Year, New Blogpost 🎉 Continuing my thoughts about design-systems, this one is about compound components, when they are a good fit and how to make them type-safe. Spoiler: It’s not about the `children` prop ...

Update: it's more like 80% of the work coming from an agent at the moment. 👀

Happy New Years! 🎊

Plans for the new year's eve? Watching ducks with my daughter. 🎊

I’m starting a short series on offline support in web apps. 📴 First post breaks down two client-only approaches: Foreground Queue vs. Background Sync. Same problem, very different UX and trade-offs. More in the article. blog.tomaszgil.me/offline-supp...

I haven't been paying too much attention to what's going on in the CSS world recent, but there's so much good stuff, especially around floating elements (popovers and dialogs). 👀 chrome.dev/css-wrapped-...

GitHub Wrapped 2025 🎉

It’s December 12th and I already maxed out my included-request usage for the month in Cursor. 🙃

If you're on React 19, upgrade. react.dev/blog/2025/12...

🆕 Knip for Editors Trust me, I've poured in A Ton of Love ✂️ This isn't just a plugin to show unused exports. It offers a unique way to view & navigate your code and connect the dots. Feels like there's so much potential here. Excited for you to try out the preview! 🙏 → github.com/webpro-nl/kn...

Gemini 3.0. 👀 blog.google/products/gem...

📚 I haven’t written much at all about the “front of the front-end” on my blog, but since I’m now working on the design engineering team @sentry.io and also maintained the design-system at adverity for some time, I have opinions there as well 😬:

Some quick observations after trying out Claude Code (CLI) for a couple tasks. 👀 Overall verdict: results were fine — good enough for day-to-day feature work. But nothing noticeably better than what the underlying model already gives you.

Cursor 2.0 is out. 👀 The most interesting bits to me: - Multi-agent support - Proprietary model (Composer) - Built-in browser - Voice mode cursor.com/changelog/2-0

I fixed some typos in the code. I commited it with the following message: "Fix types". 🙃

📚 As promised, a quick writeup on how syncing state - even if it’s between server and client state - can be avoided if we’d just derive state instead:

I want as many developers as possible to experience the joy of refactoring their code when they have a good test suite by their side. It's infectious. You'd want that feeling all the time.

💡 TIL: Zustand has an in-built middleware to persist the store (by default in local storage). See me remove all useLocalStorage hooks tomorrow. 👀

Today, I one-shot prompted a small web application, front-end and back-end included. The interface has to be reworked entirely and the backend reviewed, but it's functional. You can call me a full-stack engineer, I suppose. 🤷

I’ve been experimenting with Cursor Background Agents for a new project. Biggest takeaways: start with clear repo rules, write prompts that force planning & checks, run agents one-at-a-time early. Background agents give me ~50% of a feature. More in the article. blog.tomaszgil.me/enhancing-so...
