Hello, I'm Valeria Serna

Expert at turning coffee โ˜• and code ๐Ÿ’ป into scalable systems for data-driven impact.

About Me

Hello, I'm Valeria Serna, a data engineer that enjoys finding structure in chaos. I'm particularly passionate about building data pipelines and systems that make data reliable, accesible, and useful for gathering meaningful insights. I currently use Python, SQL, and cloud platforms like AWS to create efficient data workflows.

My B.S. in Data Science and Applied Mathematics gave me a strong background in statistics, data analysis, AI, cybsersecurity, ML, and mathematical optimization, which allows me to approach everyday tasks and possible challenges that could arise with a unique perspective and skill set.

Besides from the technical side of things, I love collaborationg with interdisciplinary teams in order to solve problems and deliver data-driven solutions that have a real impact. I have actually found that this is the most rewarding part of my work as a data engineer, as I get to learn from others while also sharing my own knowledge and expertise.

In a more personal note, I really like reading (don't worry, you can find my most recent thoughts and reviews here!), and drinking a good cup of coffee, hobby that I have recently adopted and have found to be one of the very best parts of my day. If you want to know more about it I have not given it, yet, a dedicated part of my page so, for now, feel free to contact me and ask away because I love to talk about it!
