About me

I came to finance through computer science, so I build research the way an engineer would: point-in-time data, no look-ahead bias, every result reproducible from one script, and tests that check the numbers.

  • 🎓 Now: Master of Quantitative Finance at Rutgers, focused on derivatives, fixed income, credit risk and Bayesian statistics
  • 💼 Business Development Analyst (Data & Automation), Timestamp LLC: I automate lead generation with Python pipelines, cutting prospect research from 10 hours to 10 minutes
  • 🤖 Software Development Intern, Engineta LLC: Improved NLP model accuracy by 15% and cut latency by 20%, then deployed the models on AWS EC2
  • 👕 Co-founder, ACKTUS: I run the finances for a direct-to-consumer clothing brand with 1,000+ units sold
  • 📈 CME Group University Trading Challenge: Returned 5% on a simulated $100K futures portfolio
  • 🌱 Purdue Student Government: As Director of Sustainability, managed a $25K+ budget
