Data Scientist / Data Analyst / BI Dashboard Developer / Programmer

Greetings! I am a data scientist who lives in the R & Shiny ‘Tidyverse’ and it is my mission to extract insight from your data and bring it to life in a clear and meaningful way for you and your customers. I am particularly interested in sentiment analysis and geo-spatial data science projects and draw upon a wide range of environmental and business project experience including demographic surveys, customer classifications, e-commerce data analysis, real-time fraud detection, text mining and telecommunications marketing. I have performed various regression, machine learning and clustering techniques in these roles and bring the results to the fore using the Shiny web framework. I have a wide range of quantitative and qualitative statistical analysis experience and also survey design, research project management, custom and legacy database management, stakeholder engagement and project reporting.

"Mr. Hollywood was a savior. He managed to somehow salvage our very dirty dataset and saved us from a lot of headache. He also performed semantic analysis on the data using LIWC with minimal inputs from us - you can count on him to do his own research rather than asking micro-questions. He has excellent communications skills and is a very nice person too - he even helped us with a few things post ending of the contract. Will definitely work with him again if the opportunity arises."

"Callum is a diligent and thorough freelancer. He was able to commit more than the required time to do the job to an above satisfactory standard with little direction. Reports and analysis after the work was completed was both comprehensive and accurate, with acute attention to detail. I thoroughly enjoyed working with Callum, he is friendly, approachable and timely. I would highly recommend his services and would look forward to working with him again."
