👋 Hi, I'm Alexei (HBWho)! Software Engineer | End-to-End Solutions Architect 🎓 Computer Engineering Student at UTFPR 🎓 Electronics Technician Graduate at UTFPR 💼 Software Developer at Conectivida & Freelancer

I am a Software Engineer passionate about solving complex architectural problems from end to end. My background in electronics gives me a deep understanding of hardware, while my daily focus is on building robust software architectures. I don't limit myself to a single layer; I thrive when bridging the gap between low-level hardware (IoT, C++, Linux internals), fluid mobile interfaces (Flutter, Clean Architecture), and scalable cloud infrastructure (AWS Serverless, Java EE).

An intelligent, secure smart doorbell system integrating Edge AI, IoT, and Cloud infrastructure.

Designed the full architecture: Flutter mobile app, edge AI (LLM, face recognition) on SBC, and a Serverless AWS backend (API Gateway, Lambda, IoT Core/MQTT).

Tech Highlights:

Warehouse automation inspired by Amazon/Mercado Livre—robotics, drones, web server, and mobile app.

Led the robotics and automation integration, creating a seamless flow between user interfaces and physical firmware.

• Mobile App:
• Web Server:
• Firmware:

A dashboard for Linux OS monitoring, built to deeply understand OS architecture.

• Note: All data is collected directly via system APIs and parsing the /proc filesystem. Built without any third-party monitoring libraries to ensure full control over Linux internals (Memory, Jiffies, Threads).
• Tech:

A 2D game fully built in C++ applying strict Object-Oriented Programming principles.
