About
Gui Ferreira
Minimalist, Software Craftsman, Developer Educator. I'm privileged to help developers grow through technology while building high-impact educational moments that bring exceptional value.
Hey, I'm Gui
Actually, my name is Guilherme, but family and friends call me Gui, and that's simpler and more accessible to those who don't speak Portuguese.
I've been a developer since 2006, working during the day and earning my degree at night. For years, I thought I wanted to become an Engineering Manager because I loved the teaching and mentoring part of the role. Eventually, I realized I could focus on what I actually enjoyed—helping other developers grow—without dealing with all the administrative stuff that comes with management.
In 2022, I decided to publish my first YouTube video. Honestly, my main goal was just to practice speaking English since it's not my native language. But something clicked, and I kept going.
I share anything that can help someone grow as a developer, but only if I have real experience with it. That means I might talk about architecture, testing, or AI one week, but I won't cover topics where I don't have actual stories to tell. My approach is simple: if knowledge and technology change my life, I want to make that same opportunity available to others.
These days, I'm a course author, workshop facilitator and speaker, and I hope my unique angle is bringing simplicity to complex topics. If any of this has been helpful to you, thank you for being part of the journey—it means everything to me.
Philosophy
"Simplicity is not easy, but it is possible and changes your life."
Getting to true simplicity takes work and practice. It means breaking down complex problems to find what really matters, choosing clear solutions over fancy ones, and being brave enough to cut out anything that doesn't help.
When I write code, I focus on making it understandable for the next person who reads it. When I teach, I take complicated ideas and break them into pieces that actually make sense and stick with you. Every project is about figuring out what's truly important and letting go of everything else.
This isn't just about the technical stuff—it changes how you think and solve problems. When you commit to making hard things simple, you create room to grow, you help others in meaningful ways, and you realize that the best solutions are usually the most straightforward ones.
