Currently

Graduate Research Assistant, University of Maryland - Sep 2026-present HPC I/O research for Open OnDemand under Dr. Alan Sussman, in collaboration with the Ohio Supercomputer Center and Princeton Plasma Physics Lab (PPPL).

Software Engineer (ML) Intern, AWS Redshift ML Team - Summer 2026 (completed) Shipped a native vector search prototype into Redshift's query engine (500K-50M vectors, sub-100ms) and Bedrock ML integrations that cut LLM time-to-production from weeks to days. Won the org-wide Amazon AUTA AI Hackathon among 800+ Amazon interns for a multi-model cost-aware router (3.2x cheaper inference). Case study →

GSoC 2026 Contributor - Hardened the Accord Project Agreement Protocol MCP server under The Linux Foundation. Shipped the typed service-layer port, MCP SDK 2.0 migration, PG18 + RLS smoke, paged MCP resource URIs, and the A2A wrapper design of record. Mentors: Niall Roche, Dan Selman. Blog write-up →
