About Me
"A builder who learns fast, a thinker who ships things, somewhere between backend systems and AI."
I am an Informatics student at President University, currently building systems that turn data into useful and reliable applications. Most of my time goes into backend development, data pipelines, and AI-related projects.
I have worked on RAG-based chatbots, computer vision systems, and NLP pipelines, built as part of coursework, internships, and personal projects. Currently interning as a Data Engineer at FIFGROUP and previously as a Backend Engineer at BCA.
I have hands-on experience with FastAPI, Kafka, Docker, MongoDB, PostgreSQL, and modern LLM frameworks. My current goal is to strengthen fundamentals while shipping things that work in real-world environments.
