PROFILE

Gera Shegalov

Worked on NVIDIA/spark-rapids and NVIDIA/spark-rapids-jni, focusing on build tooling, code quality, and containerization. Enhanced cross-version compatibility by refactoring Python-based shim class generation, interpolating Spark version classifiers to streamline class materialization and reduce maintenance. Improved code quality by refining Scala static analysis, excluding generated files from scalastyle checks and ensuring core sources are consistently validated, which strengthened CI reliability. Delivered a Docker build feature enabling CUDA path overrides via bash scripting, allowing flexible CUDA version management during containerized builds. Across these projects, applied Python, Scala, and bash to address reproducibility, maintainability, and deployment flexibility in complex data processing environments.

April 2025: Delivered Docker Build CUDA Path Override for NVIDIA/spark-rapids-jni, enabling HOST_CUDA_PATH-based CUDA path overrides during Docker builds to support flexible CUDA version management in containerized environments. This feature reduces environment friction, improves build reproducibility in CI, and enhances deployment flexibility across hosts with different CUDA installations. No major bugs fixed this month; focus was on delivering a robust, reusable build-time configuration capability.
