I'm Avijit Roy, a Full Stack Developer and Software Engineer specializing in the MERN stack — React.js, Node.js, Express.js, and MongoDB. I hold an MCA (Master of Computer Applications) from Sister Nivedita University and a BCA from MAKAUT, and I'm currently open to entry-level Software Engineer, trainee, and associate opportunities across India.

As a Frontend Developer and Backend Developer, I design and build responsive web applications, REST APIs, and real-time systems using Socket.IO, along with secure authentication and authorization workflows. My work spans modern web development, API development, database design, and foundational system design — with growing hands-on exposure to cloud deployment, Docker, and Git/GitHub-based workflows.

Beyond web development, I've explored AI and Machine Learning, building projects that apply predictive modeling and computer vision to real-world problems. I'm an active member of the OWASP Foundation, have solved 200+ Data Structures & Algorithms problems, and have participated in 6+ hackathons spanning web development, AI, and cybersecurity. I actively contribute to open source and continue sharpening my skills in scalable, production-grade web development.

In short: if you're looking for a Full Stack Developer, MERN Stack Developer, or Entry-Level Software Engineer based in Kolkata, India, who ships real projects and understands the full lifecycle from frontend to backend to deployment — let's connect.
