Protocol Engineer & Builder
Currently building Numa Protocol — a hybrid lending orderbook on Solana
Contributor to Marginfi v2 and core engineer behind Satoshi Perps (formerly NLX)
I’m a blockchain engineer focused on DeFi protocol design, runtime optimization, and on-chain trading systems. My work spans Solana, and EVM based chains, where I’ve built lending engines, perpetual DEXs, and developer tooling.
I care about designing systems that are capital-efficient, modular, and performant — while staying true to open-source principles.

}| Project | Description | Stack |
|---|---|---|
| 🧩 Numa Protocol | Hybrid lending protocol combining orderbook and pool-based systems. Designed a deterministic account model and a high-performance matching engine. | Rust · Native Solana · Solana |
| ⚙️ Marginfi v2 | Contributed PDA-based account architecture for deterministic addressing and auto-indexing. Built safety mechanisms like time-limited emergency pauses. | Rust · Anchor · Solana |
| 📈 Satoshi Perps (Prev NLX) | Led protocol development for a perpetuals DEX. Implemented vaults, liquidation, governance, and keeper systems for real-time execution. | Solidity · TypeScript · Hardhat |
| 🔁 Asset Rebalancer | Solana on-chain rebalancer using AMM mechanics to maintain target portfolio ratios. | Rust · Anchor · Solana |
| 💡 PariSwap SDK | TypeScript SDK enabling atomic swaps on Hxro’s Parimutuel Protocol. Simplifies integration with SPL tokens. | TypeScript · Node.js |
- Protocol Architecture: Lending, Perpetuals, and Orderbook systems
- Performance Engineering: Runtime and compute optimization on Solana
- Security: Access control, safe upgrade patterns, and risk isolation
- Tooling: SDKs, indexers, and subgraphs for protocol integrations
- Refining hybrid lending logic on Numa Protocol
- Building deterministic account systems and on-chain risk controls
- Exploring MEV-aware execution and cross-chain liquidity
Excited to work on:
- Advanced DeFi primitives (hybrid orderbooks, lending, RFQ)
- Cross-chain messaging and yield aggregation
- Developer infrastructure for Solana or Rust ecosystems
