I'm Uttam, a Rust backend developer based in Jharkhand, India. I build APIs with Axum, Tokio, and PostgreSQL, alongside local AI applications and developer tools.
I've worked on production APIs, authentication, and database integrations for a multi-tenant CRM. Now I'm going deeper into concurrency and local inference through my own projects.
