Projects

When I first began my journey into the IT world, I was fortunate to gain hands-on experience through several freelance projects and collaborations. At that stage, I valued the learning and practical exposure more than financial reward, which allowed me to quickly build essential professional skills. These projects not only sharpened my technical abilities in data analysis and automation, but also gave me the confidence to deliver real value in a business context.
