I find what breaks in DeFi before it ships.

Selected work

↗

↗

Production DeFi · DEX

TrunkSwap

Shipped a working testnet DEX demonstrating end-to-end DeFi UX from wallet connect to swap confirmation.

↗

Production DeFi · Cross-chain DEX

FerrySwap

Enabled users to interact with complex chain logic through familiar swap interfaces.

↗

Protocol research · Uniswap v4 hook

TrunkGuard

Demonstrated private, intent-based swap architecture as Atrium Academy capstone.

How I work

Research, in keypoints

01

Mechanism Design

Uniswap v4 hooks & stablecoin LVR

Oscillon — reactive fee research with state-weighted backtesting and published negative results.

02

Quantitative Research

Empirical validation before shipping

934 Chainlink days · 3 calibration datasets · self-correction when data changed the headline by 38%.

03

Adversarial Analysis

Find what breaks before auditors do

Oracle failure modes, disagreement guard blind spots, and honest findings about mechanisms that don't clear LP thresholds.

The Fee That Only Works When You Need It Most

Can dynamic depeg-aware fees meaningfully improve LP outcomes, and under what conditions? Stablecoins are supposed to be boring — USDC and USDT sit within a few basis points of a dollar, until they don't.

Two Ways to Fight LVR, and Why I Picked the Weaker One On Purpose

I spent months building Oscillon, a Uniswap v4 hook designed to protect stablecoin LPs from Loss Versus Rebalancing — the silent extraction that happens every time an arbitrageur is faster than the pool.

The Window You Can't Close: A Mechanism Design Flaw I Found in My Own Hook

I found a flaw in my own Uniswap v4 hook this week. Not from an auditor. Not from a user report. From asking myself one uncomfortable question about my own oracle design.

Track record

Experience

DeFi Infrastructure @ Judge Finance

Built the Earn dashboard with cross-chain YieldCoin balance tracking, APY calculations, and portfolio analytics for Bitcoin, Monero, and Ethereum.

Sept 2025 – Present

Full Stack Web3 @ FerrySwap

Contributed to FerrySwap, a decentralized exchange on Serai Layer 1, enabling cross-chain swaps between Bitcoin, Monero, and Ethereum.

May 2025 – Dec 2025

Market Design @ Atrium Academy

Completed the Uniswap Hook Incubator cohort, building Uniswap V4 hooks and capstone projects. Built TrunkGuard a confidential swap protocol on Fhenix using Fully Homomorphic Encryption for private on-chain swaps.

2025

Five months on Oscillon. Three years shipping DeFi in production. I backtest mechanisms, publish when they fail, and ship the infra to prove it.

About

  • ·Oscillon: state-weighted LVR model, −38% self-correction, oracle failure published pre-audit.
  • ·Production: Judge Finance, FerrySwap, TrunkSwap — subgraphs, multi-chain, v4 hooks.
  • ·Looking for: mechanism design, protocol risk, quant research where honest negatives are the job.
