I'm redesigning the cards in my ClientPortal demo, and I want honest feedback.

Next update: the number first, one line of context, then a small chart. Is it better, or worse? What would you change? 👇

[CJ Villanueva @_CjTheVillain]

@vlatdd Thats why i am wishing for. Hopefully someday. I can get remote job.

[CJ Villanueva @_CjTheVillain]

@itsvlady Yeah sounds like it. 🤣

375 pull requests merged. 19 repos. One developer and a team of AI coding agents.

UK devs 🇬🇧 say hi 👋

I'm Christian. I build web apps and dashboards for small businesses.

Who else is building from the UK?

[CJ Villanueva @_CjTheVillain]

What it built: Whenly (an Android reminder app, now in testing), two more Android apps, five demo web apps and my portfolio.

The guardrails: agents cannot push, merge or deploy without my OK. A hook checks every command before it runs and blocks the dangerous ones.

[CJ Villanueva @_CjTheVillain]

How it works: the agents (Claude Code and Codex) run on one Linux server. I drive them from my desktop. Every task gets its own branch and its own pull request.

[CJ Villanueva @_CjTheVillain]

I asked Claude Opus 5.5 to redesign Whenly's landing page.

Version 1: sloppy. Version 2: boring. Version 3: the screens looked crap. Version 4: too much floating. Version 5: shipped.

Best thing about @theo 's T3 Code? It's open source.

It didn't have Linear support, so I asked AI to add it. It did. Now my issues sit right next to my worktree, branch and PR.

Stop bending your workflow to fit your tools. Bend the tools.

[CJ Villanueva @_CjTheVillain]

AI can generate a design in seconds. Fine.

But the stuff that makes people go "I swear they can literally see what the customer needs"? The tiny animation, the colour that feels right, the detail nobody asked for. That's still taste.

That's the part worth hyping.

@acadictive Whoa!. I can't believe you followed me. Thankss.

Hi 👋 I'm Christian, a developer in the UK.

I build web apps, dashboards and an Android app on the side. Looking to connect with other devs and builders, so say hi if that's you.

@JatinChanchlan Whenly: an Android reminder app. Write a reminder in plain words, check how it was understood, then confirm. In closed testing now and looking for testers.
