Mechatronics Engineer | Data Analyst | Virtual Assistant

I am a creative and results-oriented Mechatronics Engineer with a strong background in automation, industrial systems, and data analytics. My experience includes developing customized web and mobile applications, designing preventive maintenance systems, and integrating databases, sensors, and user interfaces to optimize industrial processes. I have worked on projects that combine automation, artificial intelligence, and digital tools, such as facial recognition for user identification, dynamic web platforms for inventory and process management, and tailored reporting systems. In addition, I bring experience in content creation, social media management, and communication strategies, supported by advanced skills in Adobe Photoshop, Lightroom, and Canva, which allow me to design and optimize impactful digital content. With certified B2 English proficiency, advanced programming skills (Python, PHP, JavaScript, SQL), and hands-on expertise in frontend and backend development, I am highly adaptable to fast-paced environments. I stand out for my problem-solving skills, creativity, and ability to connect technology with human-centered solutions.
