👨‍💻 About Me

I'm a Computer Science student and Full-Stack Developer focused on building complete software products — from frontend interfaces and mobile applications to backend APIs, databases, authentication, payments, and deployment.

My primary development stack is JavaScript/TypeScript, React, React Native, Node.js, Express, MongoDB, PostgreSQL, and Redis, with additional experience in Python and machine learning.

I'm particularly interested in:

  • Full-Stack Web Development
  • Backend Engineering
  • REST APIs & System Design
  • Database Design & Optimization
  • Authentication & Authorization
  • SaaS Applications
  • AI/ML Integration
  • Scalable Application Architecture
  • DevOps & Deployment

Currently targeting SDE-1 / Full-Stack Developer opportunities.
