Cosmina-Valentina Țunea

I am a motivated person with strong teamwork skills, a focus on managing time and resources efficiently, and a passion for learning new technologies. In a recent project, I reduced the number of sensors from 8 to 2 by using better solutions. I also created custom library functions for Arduino, like delay and displaying characters on an LCD, which improved performance and made development easier.

Tutoring and Lab Assistance Program

As part of a university program, I worked as a tutor and lab assistant in the Operating Systems lab (focused on Linux and Shell Scripting). I assisted the professor with organizing labs and helped students understand technical concepts. This experience improved my leadership, communication, and mentoring skills.

Alarm system based on Arduino Uno (https://github.com/Cosmina23/Alarm‑system‑based‑on‑Arduino‑Uno.git) 

This project involves creating an alarm system using an Arduino Uno microcontroller, keypad, LCD screen, buzzer, LEDs, PIR sensors, a servo motor, and an IR remote control module. The system can be armed and disarmed using a keypad code or remote, with the servo motor managing door access. 

EasyBac App

(https://github.com/Cosmina23/IC_APP.git)

 EasyBac is a game‑based app designed to help students prepare for high school graduation exams through quizzes and exercises. Its primary goal is to provide an effective way for users to study various subjects tested in the baccalaureate exams. 

Pocket calculator

(https://github.com/Cosmina23/Fundamentals‑of‑computer‑engineering) 

The goal of the project was to implement a pocket calculator based on the MIPS architecture, processing 16‑bit data and supports 17 operations. The implementation of the calculator was done using Verilog language.
