Inspiration about this App.
When I was studying abroad in Europe, I found myself struggling to convert prices from the local currency to my home currency. I often had to use online currency converters that were not always accurate, which resulted in me overpaying for things or not having enough money to pay for something. This experience inspired me to create a currency converter app that would be accurate, easy to use, and would save people from the inconvenience and frustration that I faced during my travels.
As a student at Holberton School, I had the opportunity to turn this idea into a reality as a portfolio project. The project required me to use my programming skills and knowledge of web development to create a fully functional and user-friendly currency converter app. It was a challenging but rewarding experience that allowed me to hone my skills and gain valuable experience in the field.
