About
Software engineer working on AI systems — RAG pipelines, LLM evaluation, and agentic workflows. Currently at AskTuring.ai and a research assistant at United International University, where I’m pursuing a B.Sc. in Data Science.
I write here about the things I’m building and the papers I read along the way.

Experience
Jr. Software Engineer — AskTuring.ai · Sep 2025 – Present
Promoted from AI Engineer Intern. I own the Eval Service and Admin Dashboard, automating benchmark evaluation of RAG pipelines across HotpotQA, MuSiQue, FinQA, and CUAD. Architected Deepen Answer — a production RAG pipeline that combines extended-thinking LLMs, expanded retrieval, and an agentic gap-fill layer for research-grade answers. Build scalable backend services and REST APIs; tune retrieval through hybrid BM25 + vector search with reciprocal rank fusion.
Research Assistant — United International University · Dec 2025 – Present
Research on autonomous AI agents and multi-agent systems, contributing to publications and academic initiatives across LLMs, retrieval, and agentic workflows.
Head of R&D — UIU Data Science Club · Mar 2025 – Present
Lead AI/ML research initiatives, student projects, and workshops on transformers and deployment. Organize industry collaborations and hackathons.
Projects
Predicta — ML pipeline platform automating EDA, feature engineering, and model optimization. Cuts repetitive workflow time by ~40%. Champion, UIU CSE Project Show, Spring 2024.
Personal Knowledge Assistant — Multi-agent RAG system with semantic search, document chunking, and intelligent routing across LLM agents and a vector store.
Analyzia — AI CSV analysis platform built on LangChain agents with RAG, turning natural-language queries into visualizations.
