Embedded systems
I like physical systems that prove the code is real: motors, sensors, boards, wiring, and iterative testing.
About
Builder of small systems with a lot of care inside.
I am Costandina Saab, though most people know me as Dina. I study electrical engineering at McGill and keep coming back to projects where hardware, software, and practical usefulness meet.
How I think about building
My work has moved from classroom tech support to independent web development, embedded prototypes, and student tools. I like owning the middle of a project: understanding the need, choosing the parts, testing what breaks, and making the final thing easier for someone else to use.
That shows up in projects like Henry Jr., a four-wheel ESP32 robot; a self-sustainable Arduino garden; and BuildWith, a platform for students looking for projects and teammates.
Full-stack tools
I build web apps with practical structure: usable interfaces, typed code, databases, auth, and maintainable flows.
Technical support
I care about making technology less confusing for people, whether through troubleshooting, tutorials, or team leadership.
