  • Description: In my current role, I have been instrumental in designing and implementing a data ingestion pipeline for the Pfizer Knowledge Mining Platform, which involved fetching PDF content from PubMed and storing it in Amazon S3. I also developed advanced chat-related APIs that enhanced the functionality of the LLM-driven application. My collaboration with data science and engineering teams has enabled seamless integration with a vector database, significantly improving the retrieval of relevant articles. Additionally, I contributed to the Deloitte Internal Senior Manager Performance Evaluation Application by implementing new features and optimizing performance, resulting in a notable reduction in post-release bugs and improved data retrieval speed.
  • Achievements: I have successfully designed and implemented over 10 new features, increased application reliability through extensive unit testing, and optimized GraphQL queries to enhance data retrieval speed. My efforts in streamlining file uploads and revamping upload functionality have led to significant improvements in server load and upload speed. I also developed a text audit feature that drastically reduced compliance violations and created custom React hooks to improve code reusability. My commitment to quality and collaboration has been recognized through my involvement in code reviews and major production releases, which have resulted in critical post-release issues.
