About Me

Mon, 01 Jan 0001 00:00:00 +0000

Hello! I’m Pedro, currently working as a Fullstack Software Engineer at GOK | Inovação Digital.

I’m someone who genuinely enjoys solving problems. I see problems as an inherent part of life: we will inevitably run into them every day. So, if problems are always going to exist, why not get ahead of them? Because of this, I tend to be very solution-driven — when something needs to be done, my mind immediately starts scheming the cleanest way to solve it. Computational thinking has become my baseline engine for everything.

Here I showcase some of the most significant projects I have built. It’s like a trophy room, where each trophy represents a real engineering challenge conquered and the satisfaction of seeing code create tangible real-world impact. 😁

🏆 Project 1: UniEspaços Link to heading

UniEspaços is the landmark project of my software journey. It began as a practical assignment in Software Engineering I and evolved into my undergraduate capstone thesis. The State University of Southwestern Bahia (UESB) recognized the impact of the solution and officially adopted it to govern the reservation and scheduling of all institutional spaces (classrooms, research labs, auditoriums, sports complexes).
