Available for work
Hey, I'm Raiyan, a CSE student and software developer.
Most of my days are spent building projects and diving into algorithmic challenges in Competitive Programming. I care a lot about good craft, performance, and understanding how systems work under the hood.
When I stumble on an interesting problem or learn something worth sharing, I write about it in my notes.
I enjoy building fast, reliable web applications and crafting great user experiences. I'm currently taking on freelance projects and open to new roles. If you have an idea or need help with your product, I'd love to chat.
