About

I’m a Software Engineer and M.S. Computer Science student at Stevens Institute of Technology, with experience building backend APIs, full-stack applications, and AI-powered systems. I have worked as a Software Development Engineer at Brillio, where I contributed to a patient engagement platform using Java, Spring Boot, REST APIs, JWT authentication, SQL-backed data access, and React.js. My current work includes building Python-based research pipelines for multilingual LLM knowledge editing and evaluation across RAG, ROME, MEMIT, and IKE. Technical skills: Java, Spring Boot, Python, FastAPI, JavaScript, TypeScript, React.js, Next.js, PostgreSQL, MySQL, Supabase, AWS, REST APIs, WebSockets, JWT, JPA/Hibernate. I’m currently looking for Software Engineer, Backend Engineer, and Full-Stack Developer opportunities.
