As a developer, I have been working with Rust for several years and have gained significant experience in building secure and reliable systems. I have also worked extensively with cryptography and have a deep understanding of its principles and application in various domains. In my recent projects, I have implemented advanced cryptographic protocols such as Threshold ECDSA Signing, Multi Party ECDSA Key Generation, BLS Signature Aggregation, and Threshold Signing with BLS Signatures using Rust. I have used Rust libraries such as rust-secp256k1-zkp, pairing, and blst to ensure their security and efficiency. In addition to my expertise in cryptography and Rust, I have extensive experience in Substrate development. I have been working with Substrate for over a year and have gained a deep understanding of its architecture. I have developed several projects using its framework and have extensively used the client side of Substrate node to make use of std libraries and optimize performance. I have also developed several host functions for pallets to call functions outside the WASM boundary, which has significantly improved the performance and functionality of the projects.
