Cover image for I would like to talk

I would like to talk about software architecture, I really would like to put into a few words what it takes to make a team of developers agree on an architectural decision shift to prevent a complete disaster in an unplanned project. What it takes to look to a codebase and visualize when and where it over-complicates things due to a lack of initiative, combined with a blind following of a status-quo, and talk about how every industry does the same, creates more problems than it solves and post-pones real solutions. I really would like to be able to do that, but talking about these things doesn't get people very excited, it actually makes everyone depressed, so here is a bunch of cool pictures of the app I made with very own my Architectural Framework which empowers LLM models to build apps without falling to common industry mistakes and lack of specific direction. Interested? Send me a message!

Cover image for In a single night I

In a single night I was able to build this awesome diary PWA using by applying my very own framework architecture with Google AI Studio. I'm actually using the app myself for the first time in my career, like I'm the user of my own craft, can't believe I finally made it. Now I can think of how I can sell it, but for you who are reading here you can also enjoy the app for free at the link: https://easyaichatdiary.vercel.app/
