Prism

Teams that scale past calling a provider directly from the app run into unpredictable cost, no visibility into failures, PII/prompt-injection exposure, and no resilience when a provider degrades — usually all at once.

Fully local document Q&A: ingests PDFs, Word files, spreadsheets, and images (with OCR), retrieves with hybrid FAISS semantic and TF-IDF keyword search, reranks with a cross-encoder, and answers through a local Ollama model, with source citations on every answer.

Streamlit tool that runs Slither static analysis on Solidity contracts, ranks findings by severity, and summarizes each in plain language with a local FLAN-T5 model; a second tab forecasts next-block Ethereum base fees with a small PyTorch GRU.

Photo Search & Recognition

Serverless photo search on AWS: S3 uploads trigger a Lambda that labels images with Rekognition and indexes them in OpenSearch; natural-language queries are parsed with Lex and served through API Gateway, with infrastructure in CloudFormation.

DiningBot on AWS

Serverless dining-concierge chatbot on AWS: Lex for conversation, Lambda for business logic, and restaurant data scraped from Yelp into DynamoDB and Elasticsearch, served through API Gateway.

A Pilot Study of a Gamified CBT-Based Digital Approach for Body Image Distress and Appearance-Related Concerns

Human Behavior and Emerging Technologies (Wiley/Hindawi)

Anushka Singh (Amity) · Naman Tyagi (Amity) · Fahad Eqbal (Amity) · Dolly Sharma (Amity) · Aikaterini Bourazeri (Essex, Corresponding Author)

Co-developed a pilot-scale serious game integrating CBT techniques with AI-driven analysis to support body image distress and appearance-related concerns. The AI model interpreting user input reached 97.15% accuracy on held-out test data, outperforming a BERT-based baseline, with preliminary results pointing to gamified digital interventions as a scalable, accessible complement to traditional CBT.
