- Build an OCR pipeline for large volume of clinical summary documents that is less pixelated.
- Regularized OCR results that were overlapping with texts and try to optimize the character recognition for clinical assessments.
- Opencv Library was leveraged to identify the text-blocks (bounding boxes) which was later OCR'ed.
- Opencv + Paddle OCR engine combinationhad significantly regularized the contentsof clinically summarized documents.
- Utilized some of the pretrained models (like RCNN) to ensure that the quality of the Image files are not loosing its original information while processing pipelines.
- Fine tuned the parameters to make sure the OCR results are not violated by its original information
- Containerized the OCR components like Image preprocessing, OCR parser and output
- Pushed docker images on AWS EKS clusters.
- Developed fastapi application and hosted it on the client's AWS infrastructure

- Demographic Record Matching project (NLP) Performed Data Analytics of various matching attributes like Insurance Plan, Referring physicians and Patients
- Identified relevant attributes for building MVP for the matching process
- Developed baseline model in AWS sagemaker using record linkage library, cosine similarity module and sentence transformers
- Performed data annotation using Record Linkage annotator to build ML model
- Identified feature importance to assign weights to different fields of various data attributes like Insurance Plan, referring physicians etc
- Helped in hosting jupyter notebook instance and sql server client database on Amazon's EC2 instance to fetch the data from the db into the sagemaker studio
- Built an Experiment tracker tool in AWS environment to track the model's daily performance and automate the tool to store the output result in the s3 bucket.
