My name is Svilen. I'm a software engineer with a technical leadership and entrepreneurship background. I'm also an author, public speaker, and consultant.

Browse around to learn more about me, read my blog, or get in touch if you want to say hello.


Over the years, I've been extremely lucky to work on many interesting projects, with many talented people. Below you can find some personal highlights.


In 2016, I joined my friend Dimitar to build Heresy. We raised £755K in venture capital pre-product, and launched it in 2017. You can read more about it on TechCrunch.

Heresy was built using Elixir and Phoenix from the beginning. Elixir helped our small team tackle many of the challenges you'd have when importing and syncing data from thousands of Salesforce instances, in real-time.

It was a great journey, but in the end, we closed the company in early 2020. Lots of lessons learnt along the way.


I've had the opportunity to speak at many local and regional events. Some of them were small meetups of no more than a dozen people, while others had audiences of 300+ attending.

I don't do public speaking as much as I did in the past, but if you're looking for a speaker and think that I might be a good fit, get in touch.
