Summary
🤩
RockstarApoorv Sadana is a founder and full-stack engineer with four years of experience building developer tools and zk-rollup infrastructure from India. He leads Karnot and maintains Madara, an open-source Substrate-based framework for building zk rollups, while also spearheading tooling at Charged that simulates and intercepts Starknet transactions and exposes developer-facing APIs. Comfortable across product, DevOps, and extension development, he has hands-on experience stabilizing CI/CD pipelines and shipping Raycast and Chrome extensions that streamline blockchain developer workflows. A repeat founding engineer, he has built consumer and B2B products that scaled to thousands of daily users and optimized backend systems for low latency and robust error handling. Notably, he blends startup grit with deep protocol work—contributing to Madara and Pragma X—making him as comfortable iterating product features as he is architecting cryptographic infrastructure.
