Work Experience

Data Engineer Apprentice at Greenflex
September 1, 2025 - September 1, 2025
Data Engineer apprentice responsible for building scalable PySpark pipelines in Databricks to process 100M+ energy records. Led the development of an automated invoice information extractor using a fine-tuned LLM (Ollama) achieving ~80% accuracy. Refactored legacy Spark jobs and implemented historical data backfill; reduced redundancy and improved runtime efficiency of large-scale jobs. Industrialized workflows with Ruff, Conda, and revamped GitLab CI/CD pipelines. Monitored and maintained ML models in production and supported business teams through data literacy initiatives and model explainability.
