Hey there, I'm Guilherme Araújo 👋

Electrical Engineer turned software developer. I started out building mobile apps back in the Objective-C and Java days, and over the years grew into a full-stack engineer — comfortable across frontend, backend, mobile, and a healthy slice of infrastructure.

These days I focus mostly on backend systems, building event-driven microservices on AWS. I've worked across fintech, healthtech, and edtech, and I'm drawn to products that make a real difference in people's everyday lives — there's nothing quite like hearing that something you helped build actually improved someone's day, or solved a problem they were struggling with.

🛠️ What I work with

⌨️ Languages & Frameworks

  • Currently working with Go, TypeScript, Python, Flutter, SQL
  • Spent a good chunk of my career with Ruby on Rails — know it well, just haven't touched it in a few years
  • Started with Objective-C and Java for mobile — still have the scars 🦕

☁️ Cloud & Infrastructure

  • A great deal of experience with AWS and GCP
  • Serverless and event-driven architecture
  • Infrastructure as code with AWS CDK

😎 Beyond the day job

  • 🎲 Video games — PC, console, board games with friends, and puzzles
  • 🔭 Watching science videos and generally going down nerdy rabbit holes
  • 🎸 Guitar — 20+ years in and still a beginner, at least according to my fingers
  • 🔌 Electronics projects — on my list, right after I stop lying to myself about when I'll actually find the time

📫 Reach out or browse the repos below — I've built some open-source stuff across iOS, web, and tooling over the years, most of it showing its age.
