Profile Summary

Data Science undergraduate with hands-on experience building deployable AI systems across fraud detection, computer vision, NLP, and data engineering. I focus on evaluation rigor, clean architecture, and solutions that work in real scenarios — not just in notebooks.


Core Skills

Domain Technologies
Languages Python, C++, C#, SQL
ML / AI Scikit-learn, PyTorch, XGBoost, NLP, LLMs, RAG, PEFT, SHAP, Prompt Engineering
Data Engineering Pandas, PostgreSQL, SQL Server, ETL Pipelines, Data Warehousing, Power BI
Backend & Tools Streamlit, .NET, Jupyter, VS Code, Git
Cloud AWS, Microsoft Azure

What I Have Done

  • Built ML pipelines for fraud detection, recommendation, and forecasting with measurable evaluation metrics
  • Developed backend and database-driven systems handling authentication, workflows, and structured data
  • Designed ETL pipelines, data warehouse schemas, and Power BI dashboards for business reporting
  • Integrated LLM-based features including RAG systems, PEFT fine-tuning, and prompt engineering

How I Work

Problem understanding → data preparation → model or system design → implementation → evaluation → delivery

I focus on solutions that are not only technically correct but also reproducible, maintainable, and useful in real scenarios.


Project Areas

  • Applied AI & ML Products: Fraud detection, recommendation, and forecasting systems built with rigorous evaluation (AUPRC, recall, SHAP explainability) and deployed via Streamlit or HuggingFace.
  • Data Engineering & Analytics: ETL workflows, star-schema warehouse designs, and reporting layers that turn raw transactional data into actionable dashboards.
  • Backend & Database Systems: Structured backend logic, authentication flows, admin approval pipelines, and SQL-backed application features.
  • End-to-End Prototyping: From concept to deployable demo with clear documentation, modular code, and maintainable architecture.
