Engineering and auditing secure, high-performance Rust systems for DeFi, trading platforms, and blockchain infrastructure.

• NautilusTrader: Ported critical trading systems (Throttler, Risk Engine, Portfolio, Indicators) to Rust for low-latency trading. Built nautilustrader.io and full documentation portal.

• ARK Builders: Developed a file/folder storage system in Rust. Wrote JNI bindings to integrate with Java/Kotlin apps and implemented a custom LRU cache for frequently accessed data.

• JaegerTracing: Rebuilt Jaeger as an OpenTelemetry extension during the LFX mentorship. Implemented adaptive sampling for Jaeger V2 to optimize trace filtering for storage backends.

• Leapwallet (TON DeFi) : Implemented optimized token swap algorithms with multi-path routing for moki aggregator.

• Stealth Data Firm : Built a high-performance PostgreSQL proxy server in Rust with semantic query transformation, strict privilege management, and AWS S3 model storage integration.

• Valid Proofs, Broken Protocols: The ZK Bugs Engineers Actually Miss: Explains how valid ZK proofs can still leak witnesses, prove weaker statements, or authorize the wrong protocol action.
• Native Rust on Solana: 7 Security Mistakes That Drain Protocols: Analyzes critical vulnerability patterns in native Solana Rust programs.
• The Ability Mistakes That Will Drain Your Sui Move Protocol: Explores critical security pitfalls in Sui Move’s ability system and exploit scenarios.
• Navigating the Cross-Chain Landscape: XCMP vs IBC: Compares Polkadot's XCMP and Cosmos's IBC cross-chain messaging models, their trust assumptions, and security trade-offs.
• XCMP in Polkadot: Security Measures Every Project Should Know : Explores cross-chain message security in Polkadot, common vulnerabilities, and best practices for secure XCMP design.
