Hi there, I'm Hiel Saraiva 👋

About Me

I'm a Computer Engineering student at the Federal Institute of Education, Science and Technology of Ceará (IFCE). I focus on building reliable back-end systems and software solutions that integrate seamlessly with hardware and real-world devices.

I have hands-on experience developing web applications and APIs using Python (Django) and Java (Spring), and working with diverse IoT environments. This includes both microcontroller-based solutions, such as ESP32 projects, and proprietary IoT platforms used in enterprise and industrial contexts. My work often involves designing data flows, integrating message brokers, and ensuring secure, scalable communication between devices and servers.

I'm particularly interested in software architecture, asynchronous processing, automation, system integration, and software testing. I enjoy solving complex problems by combining clean code, solid design principles, and practical engineering decisions.
