What I'm looking for

I seek a senior engineering role building resilient, low-latency blockchain systems with strong observability, cross-chain integration, and opportunities to lead architecture and scaling efforts.

I am a blockchain engineer with 6+ years of experience building smart contracts, Rust-based backends, and cross-chain trading systems. I began with EVM and Solidity and progressed to Solana indexing, distributed backend design, and high-performance event-driven architectures.

At BitradeX I architected a Rust backend for real-time aggregation and a sub-second cross-chain token swap engine, and I integrated AI-powered anomaly detection to flag abnormal trading behaviors. At SevenLabs I developed a robust Solana RPC datasource, modular indexing pipelines, and Prometheus-based observability to improve reliability and rollout speed.

My work blends low-level smart contract optimization with scalable backend infrastructure and monitoring; I prioritize performance, fault tolerance, and clear metrics to deliver resilient blockchain products.
