Completed migration of API server that was running on AWS to Railway.I determined that Railway would make it easier to respond to infrastructure outages like this since they operate independent infrastructure. How did everyone else handle this outage?

Let customers define your product direction. 2 client meetings. 2 rejections. "Can't we just do this ourselves?" That's when you know you've failed. Your SaaS must solve hard problems simply, not look easy to build. Build what customers need now, not what you think.

I found this post on Reddit, and as someone who's building a development tool with a developer background but lacking in marketing, it was really helpful. I hope it helps you all too. https://t.co/CUDbB6XzEH

Reaching out to friends to try my product. I was terrified of "Is that all?" So I postponed. But when I reached out, everyone wanted to help. Trust I built as an employee came back. Key lesson: "If it doesn't sell, it's just a toy for yourself" Shifted to sales.

Today I asked a former colleague from my first job to consider my service. I've been hesitant to reach out due to my introverted nature, but now isn't the time for such trivial concerns. I'm going to try everything going forward.

Would you use it if you could do upscaling (AI image enhancement) and background removal just by manipulating the image URL? One user suggested this features. example: fox.jpg?upscale=2x&remove_bg=true

How to speed up Claude Code Too many rules in https://t.co/mlWxRNadnp = slower & less accurate reviews. Claude parses this file every time. One-liner prompt πŸ‘‡ β€œKeep lean: core rules only, minimize duplication/examples, write concisely.”

You set up your website and added GA (Google Analytics), but without this one thing, it won’t be much use. The β€œone thing” is filtering out your own traffic. Every time you visit and test your site, GA logs those events too. Checkout this. https://t.co/PCKYoch2TJ

Weeks 1–12: All good. Weeks 13–14: Hit usage limits β†’ fallback to Ask + Agents β†’ slower cycles. Yesterday: β€œ$200 for Max? Nah, Cursor is fine.” Today morning: Subscribed to Claude Code Pro β†’ instant wow. Today afternoon: Upgraded to Max. I should’ve made the jump sooner.
