It s the third week of working on my little side project, SimploMail.com, and to speed things up I ve been doing a lot of vibe coding. It s been fun, but a few things became obvious pretty quickly.
I stopped using the auto model setting in the IDE. When it silently switches models, the quality drops fast. I can feel when the agent all of a sudden looses its intelligence . So now I just pick one model I trust and stick with it.
I also try to keep each AI session focused on one small task. One feature, one change. After it writes the code, I go through everything myself. I check for hard coded config, make sure it didn't quietly delete a unit test to make something compile, and etc. Sometimes it does update unit test just to make it pass .
And I never commit without reviewing. The AI is helpful, but it can also remove something important without telling you. I've seen it happen enough times now .

My name is Sergey and I am a software developer.

I am here because I started building a service I wanted to build for a several years now - A pay-as-you-go email marketing platform.

I could not find a service that does not charge if I am not sending any email campaigns. So I decided to create one.
Building in public is very new to me and I have zero experience sharing about it. But I will try my best

Hey everyone! I'm Gianmarco, a software engineer based in Italy. After years of planning trips for friends and family (and being the unofficial "travel agent" of my group), I decided to build something that could do it better than me or at least faster.

I'm working on Aitinery (aitinery.com), an AI-powered travel planner that specializes in Italy. The idea is simple: instead of spending hours on Google Maps, blogs, and TripAdvisor trying to piece together an itinerary, you tell our AI what kind of trip you want and it builds a complete day-by-day plan with real places, accurate travel times, local restaurants, and hidden gems.
