Machine Learning & Data Engineer | M.S. in Artificial Intelligence @ Northeastern University

Machine learning and LLM engineering enthusiast completing an M.S. in Artificial Intelligence at Northeastern University (GPA 3.9), with four years of experience as a Data Engineer building FP&A and operational reporting systems. My work bridges production-grade data engineering with modern AI systems—covering retrieval/RAG architectures, LLM orchestration and evaluation, ML or Vision domain, and end-to-end MLOps. I like working on full-stack ML systems, including but not limited to 3D human pose or Scene data, with a strong focus on deployable, cost-aware, and reproducible pipelines.

Current reads: Andrew Gordon Wilson's keynotes and lectures on Bayesian deep learning; gated attention for LLMs (NeurIPS 2025 best paper); Google's work on nested learning and self-modifying recurrent architectures; Efficient LLM training with memory and compute optimization.
