Rahul Dev.

Backend developer/Rust · Infra · Solana

Based in India, with 2+ years of full-stack experience. I build backend services, AI applications, developer tools, and Solana programs with Rust, Python, and TypeScript.

I like digging into how things work: how async tasks run, how processes communicate, and where a system spends its time.

Let’s talk GitHub
