Experience
Summer Research Intern
Summary
What I did
- Conducted independent research in Dr. Ana-Maria Cret¸u's group on reconstruction attacks that recover individual-level records from aggregate statistics.
- Built reconstruction pipelines in Python using PuLP, CBC and Gurobi, modelling the problem as Integer Linear Programming over aggregate constraints.
- Implemented custom second-solution and uniqueness checks using integer cuts and Big-M formulations, and investigated solver behaviour, k-way marginals and limited-query reconstruction.
- Reproduced findings from existing papers on database reconstruction attacks and investigated factors influencing reconstruction success.
- Developed an ILP-based reconstruction pipeline in Python and experimented with different combinations and dimensions of aggregate statistics.
- Investigated whether successful reconstruction necessarily meant the solution was unique.
Results
- Achieved 100% reconstruction accuracy on a synthetic dataset of 10 records using specific combinations of 4-way marginals.
- Identified how the amount, dimensionality, and overlap of released aggregate data affect reconstruction accuracy.
- Tested solver behavior across 10,000 random seeds.
Teaching Assistant
Summary
What I did
- Used automated workflows to build code and run test suites when changes were pushed to GitHub.
Software Engineering Intern
Summary
What I did
- Built an end-to-end internal tenant-management application using Python, FastAPI, Jinja2 and Azure SQL, centralizing customer license, usage and lifecycle information for support teams.
- Designed REST-backed workflows, sorting/filtering, pagination, alerts and a custom weighted tenant health scoring engine to identify expiring, inactive and high-potential tenants.
- Integrated Azure OpenAI (GPT-3.5 Turbo) to generate context-aware trial-ending, upgrade and re-engagement emails directly from tenant metadata.
- Migrated persistence from CSV files to Azure SQL using SQLAlchemy/pyodbc and deployed the application to Azure App Service, completing requirements, development, testing, documentation and handover.
- Consolidated tenant information to automatically calculate health scores and identify accounts requiring attention.
- Integrated Azure OpenAI to generate personalized customer outreach emails.
- Deployed a full-stack application on Azure App Service and managed an Azure SQL Database.
- Configured cloud services and environment variables.
Results
- Built and deployed an end-to-end system that automated tenant monitoring, prioritization, and AI-assisted communication.
- Designed system to support a portfolio of hundreds of tenants.
- Estimated potential 60–80% reduction in drafting time for customer outreach emails.
