Paul Wu Email and Phone Number

• Architected and implemented scalable data pipelines leveraging big data technologies such as Apache Spark and Iceberg to process large datasets for industrial parks and enterprise investors.• Designed and optimized data models supporting advanced machine learning models and interactive visualizations, enabling actionable insights for stakeholders.• Integrated Generative AI (GenAI) into solutions for enhanced analytical and decision-making capabilities.• Provided technical leadership, strategic recommendations, and prototypes for cost-effective and timely project delivery

Leveraging Databricks' Notebooks for development, Workflows for pipeline orchestration, and its job scheduler for managing production processes, I have led multiple high-impact projects utilizing Databricks, Apache Spark, Snowflake, and Oracle, focusing on enhancing machine learning models and optimizing big data analytics. These projects extensively took the advantages of Databricks' advanced error-handling mechanisms, comprehensive logging, and automated retries to ensure robust and reliable production systems.• Databricks and Snowflake: Engineered a custom 'transformer' to convert complex legacy Oracle queries generated by a Java API into Snowflake queries. This facilitated near-real-time analysis of hundreds of KPIs from thousands of wireless network counters, reducing development time by 67%, from six months to two.• Machine Learning & AI: Led a team to achieve 97% classification accuracy for anomaly detection across 1 million mobile cells, using near-real-time processing. Integrated ChatGPT’s Generative API to enhance a web-based communication platform, driving innovative customer interactions.• Big Data Analytics: Designed and implemented a Spark-based analytical framework for optimizing wireless network performance, processing over 2 billion calls daily to identify real-time network issues. The tool significantly improved network reliability and customer experience by minimizing downtime.• OneMap Web Service: Key contributor to the design and development of the OneMap Restful Web Service for AT&T's E-Commerce platform. Successfully integrated the OSGi model into a legacy infrastructure, overcoming significant technical challenges and improving system scalability.
