Hello, I'm Raj Aryan.

Key Arguments: Led product strategy for an AI-powered platform connecting MSMEs with government schemes. Architected a scalable microservices backend with 99.8% uptime.

Evidence: Drove 35% MoM growth. Reduced application processing time by 50%. Established partnerships with 15+ nationalized banks, driving 60% of user acquisition.

Key Arguments: Architected a hybrid retrieval strategy combining sparse (BM25) and dense (FAISS) methods with a Cross-Encoder reranker to enhance answer relevance from complex scientific PDFs.

Evidence: Showcased three distinct architectural approaches, including a full-stack web demo, a Streamlit app, and a research-focused Colab notebook, demonstrating versatility in both research and production contexts.

Key Arguments: Developed an Ensemble Voting Classifier (Random Forest + Gradient Boosting) to identify gases using low-cost IR Quantum Dot Photodetectors.

Evidence: Collected and processed a dataset of ~10 million samples. Engineered new features to distinguish between gases with similar IR signatures. Predicted gas concentrations with a stable R² score of ~0.738.

Key Arguments: Founded a new venture to address key pain points for non-technical SMB owners, identified from 500+ user interviews. Architecting an AI-driven marketing automation platform.

Evidence: Solution includes GenAI Content Creation, Automated Social Posting, and Transparent ROI Tracking. Projected to improve marketing ROI by 60%.

Key Arguments: Built a multi-disease prediction system for 4 chronic illnesses. Compared 66 different models to identify the highest performers for individual, ensemble, and master models.

Evidence: Integrated SHAP and LIME to provide transparent, explainable predictions, bridging the trust gap in clinical AI. Deployed the solution as a user-friendly web application.

Key Arguments: Collaborated on a research project with IIM Bangalore to apply analytical models to complex financial challenges, such as identifying inventory writedowns and measuring director competency.

Evidence: Created an analytical approach that broke down market strategies in an intuitive way, making complex financial data more approachable and actionable for strategic decision-making.
