Passion and appreciation for coding and design since 2008. Love to create, innovate, and reach perfection with elegant work. I can adapt to new challenging scenarios and become advanced fastly, thanks to my self-learning abilities. I have very good FrontEnd skills using my design experience and creative ideas to achieve mind-blowing results, as well as Backend skills, including working with clouds, servers and backend programming languages like PHP, Python, R, SQL, NodeJS, and much more. Also, I love to build, entrepreneur and innovate on my own, that is why about a year ago I decided to start here in Barcelona with some colleagues a startup named RollingScooter about electric scooters with a CTO position. I built the mobile Apps for both users and people who maintain the service, also, I build a Desktop application connected in realtime with R backend language & Firebase to simulate the e-scooter usage during a time on a certain location among other functionalities. The purpose of the desktop application was to demonstrate how this data can become the input for machine learning algorithms to predict usages on certain locations and lower the costs. To conclude, I am that type of developer & engineer that can be anything, a data scientist, designer, web developer, Cloud Architect, mobile developer, IT specialist to provide solutions for any type of issues, great team member and leader, good English speaker, a compliant person (following the company's code of ethics and business) and much more. mai puțin
