Don’t be a "safe" coder. It's a trap. I spent half day debugging AWS Amplify config only to realize that process env NEXT_PUBLIC works, but process?.env?.NEXT_PUBLIC returns undefined because the Next.js compiler doesn't recognize the pattern. @vercel.com why you do this to me? 🤡

I had my first bot attack. Guns out now. Cloudflare and vercel bot protection did not do much. So I had to block particular FA4. Need to put rate limiting. What do you guys do to avoid this?

Ohh such a nice start to the week. I am soo over the moon. 3 years of work on our Options Trading Journal is finally paying off. Since our YT video is out, we had total 2 monthly basic plan, 1 yearly basic plan and 1 yearly pro plan sales. 🚀🚀🎉🎉 #buildinpublic #options

Gemini 2.5 on cursor was great but had some flaws. Crashes mid task Slow response And talks too much. That is why I used Claude and Composer. How is it with Gemini 3? I am not asking how it performs, it will perform superb. Does it still have these flaws? #buildinpublic

@posthog.com is amazing! I just wanted to remind that. I shipped a critical update today, did not realise there was a bug on certain edge case. Saw the bug in session replays even before customer warned us and my team mate fixed it immediately. Definitely try out session replays. #buildinpublic

I have been experimenting with Composer and it is amazing! No noticeable detriment to Claude 4.5 or gemini 2.5 but significantly faster. Not able to watch TV anymore, agent finishes to quickly. @cursor_ai #buildinpublic

We need to normalize supporting devs who give us great tools, especially when it is free. This is least we can do to return the favour. I start with @cursorful.com, it is unbelievable that this is completely free! It is demo recording tool similar to screen studio and tella.

October is going so well this year. One of my wishes from last birthday was having paying customers. This time, we have two different apps with paying customers! Promising events coming up to scale them more. I am sure next year, I will be talking about 5 digit MRR. #buildinpublic

Cursor Agent is really nice to get small changes in while you are off laptop, but somehow it gets some stupid change in.. Then I try to revert last commit talking to it, but it fails to revert a commit. Anyone having the same issue? For example it deleted supabase db types file? #buildinpublic

Your advantage as an indie hacker is not your tech knowledge or advanced features in your app. It is agility and adaptivity! Instead of endless meetings and pointless discussions, you can actually get things done quickly for your USERS. Not for your manager. Focus on this! #buildinpublic

Important for B2B, always filter the requests. Especially big companies will always find a way to complicate things. They will ask more and once you deliver, they will ask even more. Set the rules at the beginning then extend the scope step by step, not at the beginning! #buildinpublic
