I’m not quitting my 9-5. But I’m serious about building things that earn on the side. Sharing what I learn about AI, SaaS, and growing an audience. Follow if you’re building something too ⚙️

I have a confession. Until 3 weeks ago, I was a professional lurker. I was terrified of the "Post" button. I didn’t think I was a "writer." But for years, I’d been sharing my ideas in private DMs and meetings. Then it clicked: Tweeting isn’t about being a Great Author. It’s

Tried opus lately. Was impressed with all 10 minutes it took to fill my limits 🤣 What has been your experience so far?

Lately had a lot of time to think about products and all. I can't imagine that all founders are pumped by their own ideas, even if they pay the bills. What do you think?

Do you also know these days on X when almost nothing clicks? Today it seems the same 5 posts are there all the time by different people. What have you been up to?

Coding agents clearly have hit a wall If the tempo continues we will be having agents running 16-40h tasks on their own. That is a week of engineering work (if you factor in sleep / meetings prolly even more).

To the experienced people on this platform: What do you think you should have done before hitting 40? Asking for a friend 😅

"how can flash beat pro??" -> the answer is RL! flash is not just a distilled pro. we've had lots of exciting research progress on agentic RL which made its way into flash but was too late for pro. can't wait to finally bring them to pro👀

For me personally, I am here to dicuss and learn new things, gather new perspective and staying up to date. I am passionated about Software Development as a whole (no matter vibe coding or not), building digital products and science/tech in general.

Clone your past work. Seriously. Every SaaS you build can use the same: ✅ Auth ✅ Payments ✅ Dashboard ✅ Email setup Why reinvent the wheel? Reuse, tweak, ship. Your future self will build faster & smarter.

Having been a gamer my whole life that has lost his interest in it. Now got interested in AI, which would benefit from even more expensive GPUs 😅 Isn't it ironic?

Don't push effort around AI generated stuff onto others! If YOU use AI, YOU are still responsible for the outcome. If a PR is mainly generated by AI, be frank about it and FFS review it yourself first. Not based on real events as of lately /s

2027: 'AI will change everything.' 🤣 I get the sentiment, I am living in a Software Engineering bubble and there it really changed everything I feel. Not sure how much coding will be done "manually" as of 2030 or even end of 2026 alone. Any takes on this?

2024: 'AI will change everything.' 2025: 'AI will change everything.' 2026: 'AI will change everything.' At some point, something should change.

Not using AI is not an option! Spotted this on my github dashboard, stop shaming AI contributions (if well done).

Biggest mistakes I made while building the first version of my SaaS: ❌ Didn’t build in public = no accountability ❌Focused on building over distribution ❌Obsessed over details instead of solving bigger customer needs Next time will be different!

Yesterday discussed detecting AI-gen images at the sideline. Initially thought Gemini solves this, but learned it only works for images from Google's models. When will we stop trusting what we see? Are we already beyond this point?

Gemini 3 Flash is out! Seems like it could be king of price/performance, looking forward to the charts later. First need to read more about it!

Introducing Gemini 3 Flash, our frontier intelligence model, available at scale for everyone. It excels at coding, tool calling, and is stronger than 2.5 Pro across most metrics!! ⚡️ Available in the API at $0.50 in / 1M tokens and $3.00 out / 1M tokens across.
