About Me

I am a Data Scientist living in Leipzig, Germany. I have an ICT Engineering degree with 6 years working in Analytics and IT Engineering

The exciting part of my work is finding new insights amid the wealth of previously unused data.

The challenging part is to understand the business problems and translate it into actual data engineering methodologies.

I also like creating end to end data solutions for clients using a modern IT Architecture.

El-Coder is my brand, my blog and my website and it was launched in January 2021. I am sharing here my notes, my know-how and what I am actually learning.

Have fun and thank you for visiting!
