Work History

3.5Years

Data Scientist 2

Microsoft
Mar, 2024 - Present1 yr 1 month
    Working in Microsoft Bing team to enhance user experience by removing billions of Junk (Dead & lowquality) URLs from search results. Leveraged GPTbased LLMs to automate identification of Junk URLs, saving $100K annually in human labeling costs. Achieved a 75% reduction in false positives in Junk detection techniques through indepth analysis of user behavior on Edge browser.

Data Scientist

Microsoft
Aug, 2021 - Feb, 20242 yr 6 months
    Developed and deployed clustering algorithms with 99+% precision, detecting over 5 billion Junk pages daily. Engineered highperformance Big Data pipelines using Spark streaming APIs and Kafka, ensuring lowlatency blocking of junk pages. Modernized legacy Junk pipelines using Azure tools (Logic Apps, Functions and ARM), significantly reducing oncall workload.

Mentor

TensorFlow (Google Summer of Code)
Mar, 2021 - Aug, 2021 5 months
    Spearheaded a collaborative effort with fellowmentors from Google Brain to enhance the opensource TensorFlow Datasets library. Mentored a student to utilize contributions from TensorFlow & Hugging Face communities, effectively doubling the readily accessible datasets.

Software Engineer

TensorFlow (Google Summer of Code)
May, 2020 - Sep, 2020 4 months
    Introduced userfriendly features like CLI for the library, folderbased dataset generation methods, and enhanced dataset catalog. Improved backward compatibility and crosslanguage support by loading datasets without reading dataset generation code.

Data Scientist Intern

Microsoft
May, 2020 - Jul, 2020 2 months
    Pioneered the enhancement of scanned PDF accessibility by adding an Optical Character Recognition (OCR) feature in the Edge PDF reader. Enabled users to select and search text in images of PDF files, enhancing the PDF readers capability. Created a network communication workflow for making Azure Cognitive Services API calls via the browser network layer.

Software Engineer

Haskell (Google Summer of Code)
May, 2019 - Sep, 2019 4 months
    Developed an opensource HsYAML library for serializing and deserializing YAML documents in Haskell. Extended the data model to allow roundtrips while preserving comments, anchors, etc. Achieved 99% accuracy on YAMLTestSuite, establishing HsYAML as the best YAML processor.
