OK, all these discussions with other founders building or better "vibing" SaaS products brings a lot of interesting things to my mind. I'm concerned about the amount of things and apps being launched that seem to not follow "any" SDLC process and maturity or security checks. How do you see that?

🔥 Just discovered Nexus Share's REST API documentation and it's a game-changer for social media automation. What impressed me most: 1️⃣ Multiple authentication methods (direct API, browser DevTools, Cognito UI) 2️⃣ Clean data models with predictable status flow (DRAFT → SCHEDULED →

I used to spend Sunday nights queuing up the same posts I'd shared dozens of times before. Weekly newsletters. Monthly reminders. Evergreen content. Rinse. Repeat. Burnout. Then I discovered automated recurring posts. 🚀 Now? I set up my recurring content once, and 🧵

I have so many cute ok ideas on what to build next - but I lack time and focus. How do you deal with the many possibilities that AI assisted development creates? If you work in an enterprise with >500 developers - are you already using AI assisted coding?

AI is writing more code than ever—but is it QUALITY code? Most developers I know are shipping AI-generated code without thinking about security implications. It's a ticking time bomb. Teri Radichel just launched a blog tackling exactly this: writing QUALITY code with 🧵

I found another defect in the big things I was about to launch today, now I am 130+ commits that are "not pushed to production" I really need to get out of that again! :( AI makes it easy to build and build and build - but if you don't ship, you got a problem. Nexus Share is going to be better

3 months building @nexus_share taught me: shipping imperfect features > perfecting unreleased ones. My rule now: → If it solves 80% of the problem, ship it → Let users tell you what's missing → Iterate based on real feedback Perfectionism is expensive. User feedback is free. #BuildInPublic #SaaS

Honest confession: Nexus Share is 85% "vibe coded" by AI agents. I used Amazon Q Developer and Kiro to build in TypeScript and Flutter - languages I barely know. The result? I shipped something that would've been impossible alone. But here's what nobody talks 🧵
