🧠 About Me

πŸ‘‹ Hey, I'm Majid!

I'm a Software Engineer who loves building things that actually matter β€” apps people use every day, systems that are fast and secure, and backends that scale without drama.

My work spans the full spectrum: from pixel-perfect Android & Flutter apps to serverless AWS architectures, to systems-level tools written in Rust that take memory safety seriously.

I've shipped a 500K+ download Play Store app, built a Women's Health AI on Compose Multiplatform (CMP), created a blockchain identity system with Ktor, and written a high-encryption file manager in pure Rust β€” all while staying obsessed with clean architecture and fast delivery.

Outside of work, I write about software engineering on Medium and enjoy a good game of table tennis. πŸ“

πŸ¦€ Why Rust?

"C-level performance. Zero garbage collector. Memory safety enforced at compile time."

Principle In Practice
πŸ”’ Ownership One owner per value β€” freed deterministically when it leaves scope, no GC needed
πŸ“¦ Borrowing One mutable or many immutable refs β€” race conditions impossible by design
⏳ Lifetimes Compiler ensures refs never outlive their data β€” no dangling pointers, ever
⚑ Zero-cost All safety checks at compile time β€” no runtime overhead, no tradeoffs
