About Vaibhav Yalla

I am deeply passionate about the world of data engineering, where raw information transforms into powerful insights that drive smarter decisions. What draws me to this career is the challenge and the reward of building scalable, reliable, and efficient data systems that truly make a difference. I\'m a Data Engineer with 6 years of experience building scalable data pipelines and real-time analytics systems across AWS, Snowflake, Databricks, and GCP.Recently, I’ve expanded into GenAI—developing RAG-based applications using LLaMA, Groq API, FAISS, and LangGraph for document-based question answering. I enjoy combining traditional data engineering with LLMs to create intelligent, scalable solutions for analytics and search.My work spans batch/streaming ETL, PySpark optimization, and end-to-end pipeline orchestration using Glue, Lambda, Kafka, and Fabric Data Factory. I’m also experienced in dashboarding with Power BI and Looker, with a strong foundation in statistics and hypothesis testing.I’m currently seeking opportunities that combine data infrastructure with applied GenAI, preferably in hybrid or cloud-native environments.* Successfully migrated large-scale data infrastructure from SQL Server to Snowflake, achieving 80% faster processing and boosting system scalability.* Delivered a dashboard by building an ETL pipeline to extract, transform, and load data for real-time business insights.* Saved over 30hr/ day and improved machine learning model performance by 8%, by building unstructured ETL pipeline.* Achieved 98% uptime of data pipelines by implementing disaster recovery region replication for critical pipelines.EXPERTISE: Python | SQL | Spark | Snowflake | Databricks | Airflow | AWS | Azure | GCP | Tableau | Power BI | Machine Learning | LLMs | RAG | Agentic AI
