Our Team

Fixing crypto's broken foundation isn't easy. It demands rare expertise: deep financial engineering fused with hard-won crypto experience. Our founders live that fusion. They've seen the problems from both sides – and they're building the solutions.

Jan Pevzner

CEO & Co-founder

The Architect: Quant Finance Veteran & LP Note Inventor

Jan spent 25+ years building the engines of global finance. Think complex derivatives, high-stakes trading, billion-dollar platforms.

Built Trading Systems:

Led quant teams, designed market-making infrastructure (Deutsche Bank), traded at Salomon Brothers. He knows how real markets work.

Scaled Structured Products:

Helped grow Halo Investing's platform to $12.5B+. He understands risk, structure, and scale.

DeFi Innovator:

Saw crypto's potential – and its dangerous lack of rigor. Developed DualWieldSwap and the core math behind LP Notes to fix it.

Jan brings unmatched financial engineering depth. He builds the robust infrastructure crypto desperately needs.

Guyi Shen

Co-founder

The Builder: Product Expert & DeFi Survivor

Guyi brings 18+ years building products and scaling ventures in the real world, including the turbulent crypto frontier. He's a 4x founder who knows how to build things people use (like Save22, SEA's top price comparison app).

Scaled DeFi:

Led Swerve Finance's $1B+ growth surge. Witnessed firsthand how flawed liquidity models attract fleeting capital, hurting real product adoption and user experience.

Survived the Trenches:

Saw countless promising projects crippled by unsustainable liquidity schemes and predatory practices. He understands the builder's pain because he lived it.

Mastered Ecosystem Politics:

Navigated complex governance across major DeFi protocols (SWRV, ESD, DSD, YFII), learning how incentives really work (and fail).

Guyi ensures Exchequer builds practical solutions. His product mindset demands systems where great projects – not just hype – can actually win.

Faruk Mustafic

Lead Software Engineer

The Engineer: Full-Stack & Risk Architect

Faruk operates at the intersection of Artificial Intelligence, Financial Engineering, and EVM architecture. He translates Exchequer's complex financial models into secure, immutable code.

DeFi Infrastructure:

Previously at Argent, where he optimized big data pipelines for one of DeFi's most popular smart wallets.

Risk Modeling:

Spent 5 years consulting on crypto risk modeling, Monte Carlo simulations, and end-to-end blockchain architecture for startups.

The Tech:

At Exchequer, he architects the full lifecycle of LP Notes—from designing modular Diamond pattern smart contracts to engineering the off-chain settlement verification systems.

The Background:

A Co-founder (dyos) with a Master's in AI and a history of financial engineering research at Humboldt University.

Tarik Sidran

Lead Backend Engineer

The Operator: Real-Time Systems & Infrastructure

Tarik ensures that when the market moves, Exchequer moves with it. He translates on-chain chaos into precise, real-time data for the user.

DeFi Infrastructure:

Builds the high-speed FastAPI backend services that power Exchequer's live position data, pricing, and liquidity metrics.

Industrial-Grade Reliability:

Comes from a background in industrial automation (Cintio), where he engineered embedded systems for heavy machinery. He applies the same zero-failure standards from industrial controllers to financial data integrity.

The Tech:

Specializes in optimizing RPC polling and event subscription to deliver accurate protocol states without lag.

The Community:

An active member of Superteam Balkan and a key builder in the regional Web3 ecosystem.
