Boris is now available for hire Hire Boris

I revel in working remotely, I've been doing it for 20+ years. I'm looking for opportunities in fully distributed teams.
I like the internet.
I like it so much I quit my career in Civil Engineering to become a web developеr. I taught myself to code through books, online courses and working with others.
After some experimenting, I tried out JavaScript and it felt like a great fit. It bridged my previous experience in engineering with my passion for all things online. I'm very happy where this decision took me and haven't looked back!
