ABOUT ME

Machine Learning Engineer for 5 years, Python developer for 12+ years

Hi there! My name is Jon. I love using technology to help solve useful problems, and to help others do the same. My background is a combination of software development, embedded systems, signal processing and machine learning. I can mentor in any of these areas, and am especially good at the intersections of these fields.

I have worked as a software engineer full-time since 2010, and Machine Learning Engineer since 2019. Currently, I am Head of Data Science and CTO at Soundsensing.

Over my career I have worked for most kinds of clients, from startups and small technology companies, to municipalities and large multinational corporations.

I have a Master in Data Science, and a Bachelor in Electronics Engineering.

Have developed several applications utilizing signal processing. Examples including an image processing web service that applied artistic filters, rescaled and optimized images for delivery on web. It served thousands of websites over the years. At Soundsensing I wrote the entire audio processing pipeline for acoustical sensors. Also used to be a contributor to the GIMP and MyPaint open-source graphical software, and have presented at Libre Graphics Meeting et.c.

Jon was efficient, insightful and had very relevant experience! This saved me hours of googling, and many more hours of reimplementing my version control system after realising the flaw Jon pointed out. Thanks!
