I immigrated to Argentina in 2014 and due to the currency controls present in the country for years, I started using Bitcoin and cryptocurrency for my daily needs since 2015 and took a profound interest in this field. I was following the crypto industry trends all this time and started casually trading in 2021. In 2022 I had this idea to create a website that would feature all the most essential and useful tools/calculators that crypto traders and investors use on a daily basis. So I learned to code and created it myself, please be sure to check out the website in my portfolio in order to understand more about my frontend development skills, the quality of the products I create, and their extremely fast performance achieved thanks to Next.js' SSR technology.

Being especially passionate about real-time crypto analytics, I know where to get the right APIs that will provide you the access to trustworthy live data, whether you opt for free or paid APIs. I can easily integrate these data into your app using either raw data provided by the API or manipulating it in order to create custom analytics for your business and visualize it in your interface the way you want. Apart from all of this, my almost 10 years long experience in crypto gives me a profound understanding of the industry upcoming and current technologies, visual trends, and user expectations on functionality and UI/UX implementations.
