Hi, I'm a

I'm a Computer Science Master's student at Northeastern University, passionate about building reliable, scalable, and user-focused software.

With hands-on experience in full-stack development, backend systems, and AI-powered applications, I specialize in technologies like Ruby on Rails, GraphQL, AWS, React, and FastAPI.

As a Software Engineer Intern at Codecademy, I’ve built backend systems and multilingual content workflows that improve the experience for over 1 million learners worldwide.

I'm currently seeking full-time Software Engineer roles, where I can bring a strong foundation in backend engineering, cloud infrastructure, and collaborative product development.
