I build Python backends and machine-learning pipelines that read documents.

Software engineer based in Bengaluru. I spent 19 months in a full-time co-op role at British Columbia's land title registry, building serverless REST APIs on AWS Lambda and an OCR/NLP pipeline over 50,000+ scanned documents. I ship tested, Dockerized Python/FastAPI and React/TypeScript applications.

Finding discriminatory language in 50,000+ scanned land titles

Historical land title documents existed only as scanned images, and reviewing them for discriminatory language was a fully manual job.

Replaced the manual review across 50,000+ documents and saved 400+ hours of work.

IT Service DeskdatabaseREST API onAWS LambdaCorporatedatabasePython, Snowflake

A serverless API that keeps two systems of record in sync

The IT Service Desk database and the main corporate database were reconciled by hand, which caused duplicate entry and inconsistent records.

Eliminated the manual data entry and reduced data inconsistencies by 90%+.

  • AWS Lambda
  • Snowflake
  • SQL
  • REST

Redacting sensitive data without sending it to the cloud

Staff needed to redact personal information from scanned TIFFs and PDFs, and the documents could not be uploaded to third-party services.

Sensitive records stay entirely off third-party cloud services.
