Experience

Sept 2023 - Dec 2023

Machine Learning Intern at Nokia USA

• Developed a telecommunications QnA system, transitioning from Elasticsearch to fine-tuned BERT models, reducing infrastructure costs by 20%. • Implemented semantic and hybrid search capabilities, fine-tuned models, and integrated LLMs for data enrichment and query optimization.

Jun 2023 - Aug 2023

Data Engineer Intern at Honeywell USA

• Orchestrated data pipelines to migrate IoT data from CosmosDB to Azure Blob, optimizing CRUD operation costs. • Built Azure data integration pipelines and SQL-based transformation workflows to enable fire safety data analysis.

Aug 2021 - Aug 2022

Data Scientist at Shell

• Developed time series and regression models for demand forecasting, boosting trade revenue by 33%. • Engineered a PoC for anomaly detection in trade transactions using clustering, followed by regression analysis to assess the risk of flagged outliers and identify high-risk trade patterns.

Aug 2020 - Aug 2021

Associate Data Scientist

• Built a risk identification model using clustering and outlier detection techniques, to detect compliance risks in transactions, reducing manual compliance review time by 30%. •Designed ETL workflows to process consumer lending data, handling daily incremental loads of 15 GB with a focus on data validation and accuracy.
