James has been a key measurement partner for a number of years. While running a boutique analytics agency, I would bring Just Understanding Data into a number of growth transformation projects at a time, across a portfolio of B2B SaaS and D2C E-commerce clients. These projects involved solving a diverse set of challenges. Together we worked on bespoke data collection solutions, applying machine learning models to marketing challenges, and surfacing often complex ideas into easy to digest actionables that clients could act on. James is well spoken and handles client communications well. His super power is being able to create a shared understanding around the insights drawn with analytics. Without James, you’ll be leaving growth on the table. 5* recommendation from me.

James is a very nice and professional person to do business with. He doesn't mind explaining technical information to give you a clearer picture of how online business works. He has a great work ethic and I'm sure Insight Jar will go far

James is literally a legend! I asked him to perform a web scraping task that was quite tedious revolving academic abstracts and he literally did it within a week after posting the gig. He also went above and beyond and gave me tips on applying NLP techniques which worked out quite well for my solution the month after. I would highly recommend working with him for any of your data collection needs or if you just need tips/help solving any Data Science issues!

Software & Data Engineering Done Right.

I build software that is easy to use, easy to maintain, and easy to scale.
