Hi 👋, I’m Bjoern Stiel

I started my career nearly twenty years ago on the tech side of Investment Banking. I hold an MSc in Business Economics and an MSc in Financial Engineering but always had a soft spot for software.

Back in the day Excel was the tool of choice for many trading desks. It integrated easily with Quant libraries and Bloomberg market data feeds. And it was very quick to implement changes.

It was my job to develop and maintain these trading workbooks. I think, the biggest one was just over 100gb in size.

Fast forward to 2012 and I got out of banking and into self employment and consulting. Mostly Python based trading applications (think hedge funds and the likes), exchange connectivity and distributed workflows.

I also got into building a bootstraped startup together with my friend Felix Zumstein. A Git based version control system for Excel which is still alive and kicking.

Parsing and comparing Excel spreadsheets involves some computationally expensive operations. Celery has been my companion ever since.

Celery has grown in popularity and maturity since I started using it in earnest in 2012. But the lack of clear tutorials and gotchas Celery has grown in popularity and maturity since I started using it in earnest in 2012. But the lack of clear tutorials and gotchas about the nitty gritty details have been nagging me ever since.

I live with my wife and my two children in Hackney, London. I am an ultra-distance cyclist, my favourite trips involve a fair amount of pre-sunrise and post-sunset cycling and a bivvy.

I started this blog to share my experiences and thoughts on building and managing Celery based applications. If there is anything I can help you with Celery wise, feel free to drop me an email bjoern.stiel@distributedpython.com
