About me

I'm Arshdeep Singh, a full stack software developer, currently working at Stripe Stripe

I have a profound interest in software and all things tech. My journey into software began early, having built my first website in grade 7 after diving into a web development course. And I've been obsessed with tech ever since. Between my full-time job and other responsibilities, I often work on side projects, hacking away at everyday problems with skills I continually develop and refine.

Software development is an ever-changing, challenging field. I love to code and hope to make a career out of it, gathering skills and making important connections with like-minded people along the way.
