What I'm looking for

I’m looking to lead C#/.NET engineering on real-time trading or high-throughput systems—lock-free pipelines, distributed execution, and DeFi integrations—where I can own architecture end to end and ship production-grade apps.

I’m a Senior Software Engineer with 8+ years building high-performance, data-intensive systems in C#/.NET. I specialize in real-time trading infrastructure, lock-free concurrency, and DeFi protocol integration.

At Torus Trading, I architected algorithmic and click execution systems spanning equities, crypto, and DeFi. I integrated 18+ live exchanges and implemented StarkNet and Solana features in pure C#—alongside execution and signing workflows—while building lock-free, high-throughput pipelines that processed 50K+ events/sec across dozens of concurrent strategies.

I also lead production desktop and cross-platform delivery, from WPF to Avalonia, and built full-feature POS/CRM systems and real-time web experiences. Whether it’s 50+ strategy types with Kalman filtering and Johansen cointegration testing or distributed Blazor/SignalR deployments, I’m driven to ship reliable systems with strong architecture.
