Hi there 👋

🎉 I wrote a book about graphics programming and generative art using Go. Check it out!

Hi, I'm Preslav.

Preslav Rachev speaking at PyConWeb 2019

I am a software engineer with around a decade behind my back, developing data-intensive software systems and applications. I have recently started work on my independent business, focusing on education (books, courses, etc) and building my own products and services. I am also helping small teams bring their ideas to market. If you are in need of technical guidance or mentoring, feel free to get in touch.

Besides my pure developer duties, I advocate for a strong culture among software developers, indie hackers, and solopreneurs - whether through my blog, or speaking at various events. I am an avid reader, a distance runner, and a hobby musician.

Being a genuinely curious individual, I always keep an eye on challenging problems I could help solve. If yours is one of those, I’d love to hear from you. Want to get in touch? No problem! Find me on Twitter. Follow right away or send me a direct message. I am also on Telegram, Medium, and LinkedIn.
