## about

Mayank Singh Tomar

Full-stack Developer · India

I build fast, scalable web applications across the stack — TypeScript and Node on the front, Go and Rust where it counts, with a security mindset throughout. I like shipping things that are simple to use and honest under load.

I've been freelancing since 2021, shipping full-stack products for clients across web and mobile — and I lean into Go and Rust when a workload needs the speed or the safety. A stint in cyber-security taught me to build with an attacker's eye, so security and correctness aren't afterthoughts.

I care about fast, honest software: small bundles, clear interfaces, and tools that hold up under real load.
