Hi, 👋

I'm Sayan Das, a Full-stack Developer and AI Engineer currently working in Kolkata, India 🇮🇳 Over the past few years, I've been exploring different layers of the tech stack — from building modern web applications to experimenting with Artificial Intelligence and intelligent systems. Some of the technologies and areas I have been recently working with include:
Flutter
For me, every project is an opportunity to learn something new, push my technical boundaries, and build things that genuinely help people. Feel free to explore my work, projects, and experiments — and if you're interested in AI, development, or building something cool together, don't hesitate to reach out. 🚀
