About Bernardo Iannini

I'm a full stack developer building complete systems, from architecture to production deploy, mostly for SaaS, fintech and automation. Before code I came from video editing and motion design, and that eye still shapes how I think about interface and product. I also take on projects born from AI, rebuild the architecture underneath, and ship something that holds up in real use.

The path

I'm Bernardo Araújo Iannini, I'm 19 and I work as a Full Stack Developer. I build complete systems, from the architecture all the way to the production deploy, and I'm studying Web and Mobile Development at COTEMIG. That study walks side by side with what I already ship in the real world.

I got into tech in 2025, but I brought an older creative side with me. I came from video editing, motion design and visual effects, and that eye still shapes how I think about interface and product. For me, function and looks get solved in the same decision.

I work with SaaS products, fintechs, web platforms, automations and custom solutions. I also take on projects that were born from AI (Vibe Coding): I start from the rough prototype, fix the architecture underneath and turn it into a scalable system that's actually ready for production.

What drives me is solving real problems with technology, and I always go for the simplest, most scalable and best structured way to do it. It's not about collecting tools. It's about shipping something that works, holds up under real use and truly solves the problem.
