Mathematics and Business Administration at Northeastern University, class of 2028. I work on quantitative finance and the systems around it — research stacks, market tooling, and applied LLM infrastructure.

closebooks-app — AI-assisted month-end close for CPA firms. Next.js, Supabase with row-level security, Anthropic Claude for transaction categorization, Stripe billing, QuickBooks Online journal-entry push. Sole engineer. Deployed, billing in test mode, no automated test coverage yet.
cricstate — A pre-registered negative result. I asked how much predictive signal exists in ball-by-ball cricket beyond match state, froze the decision rule before reading the test split, and measured. Match state captures ~93% of the recoverable signal; player identity adds +0.31%, below my own materiality bar, so the hierarchical model I intended to build was declined on the evidence. 16,754 matches, 4.75M deliveries, match-level bootstrap, leakage canaries in CI. The result is the refusal.
nucarbon — An estimation dashboard for the carbon cost of campus AI use, built in a week for the Northeastern Sustainability Incubator. Models rather than measures, and says so on every page.
startup-investment-analysis — Segment ranking over ~41k cleaned startup funding records. Course capstone, notebook in Russian, English summary in the README.
Sole engineer at Glacier Capital Systems, building a Python research stack for a live options trading firm — scanner, multi-factor scoring, volatility surface, regime detection, and a real-time Next.js alert dashboard. Before that, daily market briefings on OFZ bonds and MOEX flows at BCS Bank's investment banking division, plus DCF and comparables work across energy and metals.

I try to publish negative results and known limitations alongside the work. Every README here states what is unfinished, untested, or simulated. If a repo says something is in production, it means deployed and reachable — not that it has customers.
