CTO @ Future Median · M.S. Information Systems, Northeastern University

Portfolio · Resume · GitHub · LinkedIn

I ship AI systems that earn trust through verification, not vibes — agents with their own gates, RAG pipelines graded on accuracy rather than demo polish. Currently CTO at Future Median, a nonprofit closing the healthcare-education gap, architecting the platform on Next.js, three.js, Supabase, and open-source LLMs. Along the way: 43 public repos, two peer-reviewed papers, one registered software copyright, and a KGC 2026 poster-session win.

Real repos, real metrics — every number below is from a shipped project.

Neo4jSnowflake CortexLangChainStreamlitPlotly Grounds Llama 3 over a 57,877-node Neo4j knowledge graph (19,883 attractions, 352 cities). A triple-validation pipeline blocks invalid Cypher before execution, holding 74% accuracy in query generation across six interfaces. KGC 2026 poster-session winner.Repo

Next.js 15three.jsNASA GIBSNOAA GFS Real NASA satellite imagery, a physically-computed day/night terminator, animated global wind from live GFS data, and 1,200 real cities lighting up as the terminator crosses them — plus a Mars twin and a 6,000-year city-growth time machine. Live demo · Repo

Google ADKGemini 2.5 FlashCloud RunSQLite Four specialized agents collaborate on sprint planning, standups, and retros over real sprint data instead of gut feel. Ships with 30 passing tests. Live demo · Repo

Tauri v2RustReactOllamaSQLite Local-first assistant: ask it to build a new skill and it writes sandboxed code plus a test, proves it by running the test, and refines on failure. Prefers local Ollama, falls back to free cloud tiers. Ships fully open source. Repo

Next.jsOpenAIFirebaseTailwind Customizable response style, language, and length. Tested with 500+ students on campus, reaching 95% query-resolution accuracy. Live demo

Elastic Agent BuilderMCPPython Multi-agent disruption detection and automated recovery on Elastic Agent Builder, wired together with the Model Context Protocol — built against a problem measured in $184B of annual global disruption cost. Built for Elastic Hackathon 2026. Repo
