As a seasoned data scientist and survey specialist with over 12 years of experience in the market research industry and academia, I bring a wealth of expertise in survey design, sampling, statistical analysis and automated data processing. My academic background in Statistics, Sociology and Psychology complements my practical skills in statistical modelling, data engineering and questionnaire programming. My strong analytical skills and methodical approach ensure reliable and efficient work, while my proficiency in the Linux command line and diverse tech stack including bash, awk, SPSS, Python, R, SQL, and more, enable me to tackle complex data challenges with ease. I specialize in research design and statistical modeling, delivering results that meet academic standards. With competencies in hypothesis testing, validation of measurement instruments (EFA, CFA, CB-SEM | SPSS AMOS | R lavaan | JASP | PLS-SEM) and customer segmentation, I excel in providing fact based insights to my customers. I am a trusted partner for reliable data solutions. Let me bring my passion for data and research to your projects, exceeding your expectations with quality results.

We worked with Benjamin for some projects now, and the quality standards have been high in all of them. He's been brilliant when it comes to the job done, but also answering questions and providing help. We are really happy with the results as we were in all past projects with Benjamin.

We worked with Benjamin in several different projects, and the quality of the delivery was always top. He was also able to give us advise when it comes to the very design of the project. We will consider Benjamin as the first option for future projects for sure.
