Hello there! 👋 My name is Mina, and I am a full-stack web developer with a strong background in Java, Spring Boot, web automation, and data scraping. I hold a Master’s degree in Software Engineering and Information Technologies. Since the end of my Bachelor's in 2017, I have been working as a Teaching Assistant in the Informatics Department, where I teach students Java, Spring Boot, and web technologies. Beyond traditional web development, I specialize in web automation and web scraping, particularly for e-commerce platforms. I have worked on projects that involve extracting and analyzing product data from major retailers such as Amazon, Walmart, Best Buy, Costco, and Lenovo. To achieve this, I utilize tools like Selenium (Java & Python), Scrapy, BeautifulSoup, and Requests. Additionally, I have developed price monitoring and comparison systems that track product changes across multiple platforms, integrating features like email alerts, web notifications, and Microsoft Teams API notifications. With a blend of academic and real-world experience, I bring both technical expertise and a passion for problem-solving. I am always eager to collaborate on challenging projects, whether in full-stack development, automation, or data scraping. Looking forward to working on exciting new opportunities! 🚀
