Kevin Alexandro
I'm a Management student with a passion for software development, specializing in Flutter for mobile apps and JavaScript for web development. Through freelance projects since 2019 and intensive training in 2023, I've created websites for various businesses and developed side projects including a social media app and e-learning platform. I blend my management background with technical skills to deliver impactful digital solutions.
About me
