Summary
🤩
Rockstar🎓
Top SchoolYoseline Angel is an interdisciplinary scientist-engineer with 13+ years applying remote sensing, machine learning, and GIS to water and food security, precision agriculture, and ecosystem monitoring. Currently an Assistant Research Scientist at NASA Goddard after a postdoc there, she translates UAV and satellite hyperspectral data into actionable vegetation and land-surface indicators across deserts, forests and wetlands. Her engineering roots include leading corporate GIS and high-accuracy GNSS networks for O&G operations in the Orinoco and Amazon basins and designing spatial data infrastructures that bridge industry, academia and conservation. She pairs fieldwork and in-situ campaigns with advanced computer-vision and ML models, and uniquely blends applied security-focused software contributions (notably to privacy/censorship tools and crypto code on notable repos like tor and obfs4) with Earth-observation science. A multilingual communicator and international speaker, she specializes in turning multi-scale sensor data into interpretive frameworks that inform climate resilience and resource management.

Yawning/obfs4
May 2014 - Sep 2022
The obfourscator (Courtesy mirror)
Role in this project:
Back-end Developer & Security Engineer
Back-end Developer & Security EngineerContributions:134 commits, 10 PRs, 91 pushes in 8 years 5 months
Contributions summary:Yoseline primarily focused on developing and maintaining the obfs4proxy code, addressing security and feature enhancements. Their contributions included refactoring code for a unified client/server binary, implementing replay detection in handshakes, and hardening the handshake process with client authentication timeouts. Furthermore, they introduced and refined padding techniques, enhanced logging practices, and addressed several reported bugs. These changes reflect a deep understanding of the security considerations involved in the project's goal of censorship circumvention.
DaGenix/rust-crypto
Jan 2015 - Feb 2015
A (mostly) pure-Rust implementation of various cryptographic algorithms.
Role in this project:Back-end Developer
Back-end DeveloperContributions:17 commits, 7 PRs, 18 comments in 18 days
Contributions summary:Yoseline made significant contributions to the `rust-crypto` repository, primarily focusing on implementing and optimizing cryptographic algorithms. They added support for XChaCha20, a variant of the ChaCha20 stream cipher, and also implemented the HKDF (RFC 5869) key derivation function. Furthermore, the user improved the performance of Salsa20 and ChaCha20 algorithms by optimizing the processing loop and leveraging SIMD instructions. These changes enhance the cryptographic capabilities and performance of the library.
