A comprehensive application designed to assist teachers in grading students utilizing GenAI models. As a back-end and GenAI developer, I created the API endpoints required for front-end integration and developed prompts for the AI model. Additionally, I collaborated in designing the application architecture to ensure efficiency, scalability, and ease of maintenance.

Developed a RAG application using Python hosted on Azure infrastructure to enhance client-customer interactions through a sophisticated chatbot interface. As a back-end and GenAI developer, I created API endpoints for seamless front-end integration and engineering prompts for the GenAI model.

Additionally, I implemented complex web crawling and scraping techniques to ensure comprehensive data collection, followed by data preprocessing tasks, including normalization and cleaning. I tested and selected optimal data parsers for various data types, such as JSON and text, which contributed to an effective chunking strategy.

Furthermore, I designed and deployed indexes with configurations that support multilingual functionality, integrated embedding models, and established an automated ingestion pipeline to ensure the chatbot's data remains current, enabling accurate and timely interactions.

Developed an application focused on extracting and anonymizing personally identifiable information (PII) from scanned and photographed medical documents. As a software developer, I collaborated in designing and developing the solution, working extensively with AI models to perform optical character recognition (OCR) on images and identification of PII entities and the reconstruction of original documents, with PII securely encrypted and incorporated into rasterized PDFs.

Built an end-to-end agentic application for processing invoices and receipt images, integrating AI models for OCR and GenAI for data extraction. I designed and implemented the entire solution, including the back end, front end, and deployment.

Integrated enterprise data for a multinational retail company. I developed ETL processes and system integrations using FTP, SFTP, and FTPS protocols. I also automated operational workflows and provided technical support for production applications.
