Hi, I'm Raiyan Chowdhury! Nice to meet you!

I’m a student majoring in data science I'm just trying to learn new things and build useful projects that impact real-life along the way
As of right now, i am dabbling in the art of React, Node.js, and Python.I hope to learn a lot in the coming years!

Technical Focus

Areas where I spend my time building and learning

Data Engineering

Building efficient data pipelines, working with structured and unstructured data, designing database schemas, and optimizing query performance. Python, SQL, and Pandas are my primary tools.

Backend Development

Creating APIs, managing application logic, handling authentication, and integrating with databases. Currently expanding into distributed systems and cloud architecture.

Applied Machine Learning

Working with NumPy and Pandas to build data-driven applications. Focused on practical implementations rather than theoretical research—solving real problems with ML techniques.

System Design

Learning to architect scalable systems, understanding trade-offs, and making informed decisions about technology choices. Studying patterns from production systems.

Why Hackathons

I'm preparing for competitive hackathons to work alongside developers who ship fast and think clearly. The time pressure, technical constraints, and team dynamics at hackathons force better decision-making and faster execution—skills you can't learn from tutorials.

Currently applying to HSIL Harvard Hackathon and similar programs. Looking for opportunities to build with people who prioritize impact over polish and learn by doing.
