From research to running code

Papers argue. Products have to work on a Tuesday, for someone who never read the paper.

LinkScape

Co-founder & CFO · January 2026 to present · fiscally sponsored by Hack Club

A student-run nonprofit that turns technical ideas into tools and programmes other students can actually use. I look after financial planning, sponsorships and operations, which in practice means budgets, compute costs, and making sure the money is there before the build starts.

Flagship — Resonaite

A headset reads eight EEG bands once a second and the audio engine re-mixes the track in response, so the music changes while you are still hearing it. Seven stages of filtering keep it sounding like music instead of a test tone: modulate audio the obvious way and what comes out is a hearing test. I am project manager and full-stack developer.

Research prototype, not a medical device. No clinical validation, and nothing here is a therapeutic claim.

VitaTex

Team lead · Diamond Challenge Global Finalist

A smart garment designed around the thing wearables usually get wrong: the burden of wearing one. It senses on the garment and runs inference on the device, so it interrupts you only when a reading has actually changed. I directed strategy, market research and financial modelling, and delivered the pitch at the University of Delaware finals.

Ring-Ing Career Technologies

Researcher & developer · June 2026 to present

A career-technology startup. I run market and user research, build the partnership pipeline, and ship full-stack features into the production codebase.

PoliScope

Built over a weekend at HackHarvard 2025

A bill's text is public. So is the list of its sponsors, the lobbying filed against it, and the money that moved through the campaigns of everyone who voted. Connecting those four public records by hand takes an afternoon per bill. PoliScope does the joining: a LangChain and LangGraph retrieval system reads Congress.gov, GovInfo and FEC filings together, traces how a bill's language changed between drafts, and reports who was pushing at each revision. It runs on Google Cloud Run.
