About Me
Hi there! 👋🏼
I’m Hersh, a Software Engineer based in London with a passion for everything tech. I’m currently a Senior Software Engineer at HubSpot, and previously worked at Bloomberg LP. I also used to live as a monk in a monastery, where I spent my time meditating, teaching others and connecting with people from all walks of life. I’m not your typical engineer, that's for sure!
I created this website to showcase my experience, skills and various technical projects. If you’d like to get in touch with me via email, feel free to hit the button below.
