Senior🎓
Top SchoolDmitry Baryshkov is a Senior Staff Engineer with 26 years of deep experience in Linux kernel and userspace development, currently at Qualcomm and long active in OpenEmbedded and Linaro. He is a seasoned systems and kernel programmer who has led development of the IEEE 802.15.4 stack and driven low-level device driver, firmware and board support work across ARM, MIPS and PowerPC platforms. Dmitry pairs embedded systems expertise with cryptography contributions in notable RustCrypto projects—adding OID support and refining RSA signature traits—demonstrating fluency across C kernel-land and modern Rust security code. He also brings practical build and DevOps know-how from contributions to OpenEmbedded core, improving cross-compilation and SDK workflows. Based in Micronesia, he combines long-form open source stewardship with hands-on bugfixing and architecture work on constrained hardware.

Aug 2022 - Dec 2022
RSA implementation in pure Rust
Role in this project:Back-end Developer
Back-end DeveloperContributions:42 reviews, 13 commits, 37 PRs in 4 months
Contributions summary:Dmitry primarily worked on implementing and refactoring RSA signature implementations within the `rustcrypto/rsa` repository. Their contributions include defining and integrating `Signer`, `Verifier`, and `Signature` interfaces, adding modules for PSS and PKCS1v15 signatures, and incorporating testing for verification error handling. The user updated RSA signature traits, implementing key-to-DER conversions for public keys, and implemented support for encoding private keys to PKCS#8 DER format and hazmat signature traits. This involved significant code changes, including the introduction of new structures and traits, and refactoring to align with the signature crate's API.
