I'm a backend engineer specializing in Rust, with hands-on experience building real-time data systems and blockchain integrations on Solana. I work with Tokio-based async services, REST/WebSocket APIs, and database-backed backends using PostgreSQL and SQLx. On the blockchain side, I've built live on-chain data pipelines for Solana — indexing swaps, reading AMM state, and integrating with RPC nodes in production. I care about writing clean, maintainable Rust that actually works under load — not just prototypes. If you need someone who takes correctness seriously and knows the Solana ecosystem from the inside, I'm a good fit.

DeFi Protocol Engineer & Senior Rust Backend Developer I design and build production-grade DeFi protocols and backend systems using Rust and Solana, with hands-on experience across lending and borrowing protocols, stablecoins (CDPs), swaps, interest accrual engines, liquidation systems, and oracle-driven risk management. My work focuses on protocol correctness, capital safety, and deterministic execution — from on-chain lending logic and liquidation thresholds to off-chain services and real-time infrastructure. I stay deeply involved in implementation, writing and reviewing production Rust code while owning system architecture end-to-end. Core expertise: DeFi protocol engineering: lending & borrowing, CDPs, swaps, interest & liquidation logic Rust backend systems: Actix-Web, Tokio, Diesel, Subxt Solana & Substrate protocol development (Anchor, runtime integrations) Zero-knowledge & confidential execution: zkVMs, RISC Zero, MPC / Arcium Event-driven and real-time systems: Kafka, Redis PostgreSQL, Docker, CI/CD, production deployments Alongside protocol engineering, I bring strong system design and delivery discipline, enabling me to take complex DeFi ideas from concept to secure, production-ready systems without sacrificing performance or safety. I work best with founders and teams who need a senior, hands-on engineer who can architect, implement, and ship critical protocol infrastructure — not just advise. I’m open to senior Rust / DeFi engineering roles, protocol architecture work, and long-term engagements where deep ownership and execution quality matter.
