AnGithubManager: an application for my day-to-day life as a developer

What I Built with Google Gemini

My last few months have been focused on creating various projects as part of my AI learning journey.

I'm a Git and GitHub enthusiast, but I didn't interact much with the interface. Lately, however, I've found myself needing to use it, but working on multiple projects simultaneously made navigating the GitHub interface quite cumbersome. To address this, I started the AnGithubManager project using Google AI Studio.

This is where Gemini solves my main problem: creating a simple pull request without having to think about it automatically, saving a significant amount of time, and above all, providing invaluable support when my head is spinning with problems.

What I Learned

I learned about the real-world, production implementation of Gemeni services.
As a side effect, I also learned to use Google AI Studio.

Google Gemini Feedback

What worked best was that it could be implemented from day one.
The most complicated part at the time was keeping it running in different environments such as Google AI Studio, local, and production, due to technical limitations in Google AI Studio, which didn't support enviorments by default. Therefore, I had to hardcode a backend URL to call if it couldn't find a valid environments.

🛒Shopping list to make shopping faster - AnQuickMerca

The Community

I don't know if my community exists, but if it doesn't, it wouldn't be bad to create one; it's simply about going shopping.

What I Built

What I created (or what I tried to create 😅) is a shopping list app, but with a key difference compared to other apps: it optimizes your route within the supermarket. The idea is to shop more quickly and efficiently, avoiding that feeling of wandering around thirty times to pick up three things… or worse, arriving at a new supermarket and getting lost in the aisles looking for a loaf of bread or even a stocker, who's always there… until you need them and they mysteriously disappear 🫥.

The app is based on a very popular supermarket in Spain (Mercadona), mainly because of its physical layout, data availability, and because it's the one I frequent most (hehe). Even so, the approach can easily be applied to any other store.

And this is where the community comes in: it would be responsible for updating locations, notifying users of stock shortages, or other details that a company normally can't (or doesn't want to) share. It's true that I still need to polish this part a bit (hehe), but the idea is clear.

Remember that this is a demo; therefore, some data may not be 100% accurate, and it's not yet available to end users. But if it's successful, and the community supports it, we could develop it further and implement it for real-world use. 🙂

What I'm Most Proud Of

Well, what I'm most proud of is being able to put it together with such short notice, since I only found out last week, but honestly, it turned out much better than I could have ever imagined.
