About Me

I am a Master's student in Artificial Intelligence at the University of Jyväskylä, Finland, and a software engineer focused on building scalable, production-ready systems. My interests span language models, retrieval-augmented generation, full-stack development, and cloud-native architectures.

Alongside industry work, I enjoy working on applied research problems at the intersection of natural language processing and trustworthy AI, with prior experience on fake news detection for Bangla.
