I really do know Google Sheets and Apps Script like the back of my hand, its quirks, uses, limitations and sometimes even better alternatives. I can optimize calculations to speed up performance or create a whole new accessible product for your use cases.

At Ocado Technology I pushed the limits of Google Sheets and Apps Script to build a model with millions of calculations which provided indepth sizing and productivity modelling for the whole company and prospective clients. It was at the centre of all warehouses built by Ocado and continues to be.

I am also more than happy to teach others about everything I know, I am not secretive and want to share the knowledge as much as possible.
