About

Rahul Karna

I build production web apps end to end—frontend polish, API design, data modeling, and deployment—with an eye for maintainability.

I care about fast feedback loops, accessible interfaces, and observability so teams can iterate safely. Currently deepening skills in edge performance and design systems.

Currently: Exploring distributed tracing and advanced Next.js patterns.
