Hey, I'm Ray!!

Dual Master of Science student at Tufts (Computer Science + Innovation & Management), graduating December 2026. Received my Bachelor of Science Degree in Computer Science and Management at the University of St Andrews in Scotland.

I like building things that work. Most of what I do sits between software engineering, data, and finance.

What I've been working on

  • 🧩 PuzzleFlix β€” full-stack puzzle platform (React, Node.js, MariaDB) β€” repo
  • 🚲 Bayesian CitiBike Prediction β€” predicting ride destinations across 5.2M+ trips using Bayesian logistic regression
  • πŸ” Encrypted Messaging β€” end-to-end encrypted chat with RSA-2048 and challenge-response auth
  • πŸ—³οΈ Raft Consensus β€” leader election and log replication in Go

Tools I reach for

Languages: Python, Java, JavaScript, Go, SQL, C
Web: React, Node.js, Express, Vite
Data & ML: scikit-learn, PyTorch, PyMC, pandas
Infra: AWS, Docker, PostgreSQL, MariaDB, GitHub Actions
