Arihant Deva — Finance + Engineering

Builds autonomous equity research and trading systems. Currently shipping Leviathan — an autonomous equity research platform that turns a ticker into a full DCF model, research memo, and investor deck. Looking for the next seat where research rigor and engineering throughput compound.

Professional

Where I've been, in chronological order — from the first ticker to the current seat.

Early

Started trading

Got curious about markets as a teenager. Self-taught from filings, transcripts, and primary sources rather than influencers. Quiet, long, compounding interest.

Niche conviction

Built early conviction in a then-niche corner of markets. Spent years researching it before it was mainstream. Wrong often, right enough to keep going.

Drawdown → discipline

Learned the hard way that conviction without risk management is just a story. A drawdown taught more than any course. Built checklists, position-sizing rules, and a "thesis-kill" file for every position.

School

Millburn High School

Honors coursework, AP-heavy load in math, economics, and the sciences. Where the markets habit started turning into something more structured.

Investment Club — President

Ran the club, restructured the pitch process, mentored younger members on building real DCFs instead of vibes-based price targets.

Rutgers Business School — Finance & Analytics

Dean's List. Coursework in valuation, econometrics, and accounting forensics.

Internships

FinBotX — Quant / research intern

Worked on systematic equity signals. First time touching production-grade backtesting infrastructure.

Work

Independent quantitative research

Built mean-variance portfolio optimization on the S&P 100 in Python (PyPortfolioOpt · cvxpy · scipy). Layered K-means preselection, GARCH(1,1) volatility via arch, covariance shrinkage, and weight-bounded constraints feeding the efficient frontier. Backtested through tail events (including the COVID drawdown) against equal-weight and proportional-weight baselines. Outputs: optimized weights, drawdown curves, Sharpe-maximized portfolios.

Tags: PyPortfolioOpt · cvxpy · GARCH(1,1) · K-means · covariance shrinkage.

Pivot

Independent research → Leviathan

Realized every sell-side report I read could be assembled by an agent if I gave it the right tools. Started building.

Now

Leviathan

Institutional-grade autonomous equity research platform. See Projects → Leviathan for the full breakdown.

Next

Looking for the next seat

Targeting roles where research rigor and engineering throughput compound.

Creative

Side-A is writing and music; Side-B is live field notes from running real money. A sticky-whiteboard of pinned tiles, some finished, most in flight.

Essays

LVT.MEMO.001 — Why I'm building Leviathan

2026.03. Origin essay on the case for autonomous equity research — why a single analyst with a model assembly line beats a team with spreadsheets, and what that implies for the sell-side stack over the next five years.

LVT.MEMO.002 — DCF, agent-assembled

2026.04. Walks through the WACC → DCF → bear/base/bull pipeline end-to-end: where data is sourced, where assumptions are bounded, where Monte Carlo enters, and how forensic-accounting checks gate the final BUY/HOLD/SELL.
