    As a Python Engineer with a Master's degree in Computer Science and an 11-year career in the tech industry, I bring extensive knowledge and experience to every project. My skills lie in Python development, data manipulation, AI technologies, system administration, and DevOps practices. In Python development, I've applied my skills across a range of applications, from data extraction and manipulation to computation and visualization. Recently, I leveraged the OpenAI API to develop a medical chatbot, demonstrating my expertise in AI and machine learning technologies. I have significant experience in data collection, scraping, and automation, and I've consistently managed large datasets effectively and efficiently. Coupled with my extensive experience in AWS, I can provide comprehensive solutions for businesses seeking to leverage the power of their data. I'm adept at DevOps tasks and have years of experience setting up and managing CI/CD pipelines, which helps to ensure rapid, reliable, and efficient software delivery. As a system administrator, I've worked mainly in Linux environments, managing various services like web (Apache, Nginx), backup (Bacula), and private cloud (Seafile), ensuring operational efficiency and resilience. One of my key achievements is the development of a GUI for scientific software, which demonstrates my ability to navigate complex scientific concepts and deliver quality solutions. As your Python Engineer, I offer not just technical expertise but also adaptability, a commitment to achieving project goals, and a collaborative approach. Let's transform your ideas into innovative solutions.
