PROFILE

Daniel Sosa

Over the past year, Sosa Garcia engineered and maintained core build, packaging, and quantization workflows across TensorFlow and LiteRT repositories. Leveraging C++, Python, and Bazel, Sosa modularized quantization tooling, refactored build systems, and automated Python wheel packaging to streamline cross-platform deployment. In google-ai-edge/LiteRT, Sosa introduced Manylinux-compliant packaging and Python API wrappers, improving integration and distribution. For Intel-tensorflow/tensorflow and ROCm/tensorflow-upstream, Sosa cleaned up dependencies, modernized quantization libraries, and stabilized CI pipelines, reducing technical debt and maintenance risk. The work demonstrated depth in build automation, dependency management, and code hygiene, resulting in more reliable, maintainable, and scalable ML infrastructure.
