About Blas

I have developed my professional career mainly as a GIS developer with more than 4 years of experience in this field. I have principally used Python (NumPy, Pandas, Matplotlib...), SQL, JavaScript and different Geographic Information Systems. Furthermore, I have had to code with other languages such as R. I am currently working as a backend developer with Python.

I studied a Master's Degree in Geographic Information Technologies in Alcalá de Henares, which gave me a broad vision on Geographic Information Systems, data analysis, web development and remote sensing. In addition, I studied for a Professional Certificate in Web Applications Development which gave me basic knowledge of front-end and back-end development.

In my daily work I have used English frequently, participating in international congresses such as the EGU General Assembly, giving training such as the Copernicus Climate Data Store workshop and contacting clients and partners.

I am currently studying a course on UI/UX at the art school of Murcia during the mornings and I would like to work on projects in the afternoons and weekends.
