My Expertise

I am a Chemistry Ph.D now traveling the path of a Site Reliability Engineer. I thrive in challenging, constantly changing environments. Lately I have been immersed in Site Reliability Engineering, helping to build a great SaaS company at Sage. I design and implement data pipelines on top of AWS infrastructure. I have over 5 year’s experience in the management of international technology projects of a complex nature. I have strong technical abilities in Python, AWS and software development tooling. During my Ph.D I acquired solid skills in data science, public speaking and project management. I have a proven ability to apply the latest research and techniques to solve a variety of scientific problems.


My main development languages are Python, C# and C++. I use Visual Studio Code as my main integrated development environment, although I am fast becoming a JetBrains convert.

Data Science

I use Python and PostgreSQL as my main data science languages. I use Scikit-learn, Pandas, Matplotlib, NumPy and Seaborn libraries to see and understand predictions, outliers, and patterns in data. I use PostgreSQL for handling databases


Published first author of numerous scientific research. Adept with technical writing and data presentation, going from initial ideas to beautifully typeset documents and presentations
