Worked on sensor-based hardware projects using Arduino IDE and Tinkercad — writing code for ultrasonic, gas, force, and PIR sensors and building functional prototypes from scratch. Led a small team through full project cycles, managing timelines and delivering working builds on deadline. What this internship really taught me was how coding behaves outside the browser — where a logic error doesn't just break a UI, it breaks a physical system. That experience of seeing code produce real-world consequences sharpened how I think about writing reliable, predictable code — something I carry directly into my frontend work today.
