What I'm looking for

I am seeking senior backend or infrastructure roles focused on high-throughput, low-latency distributed systems, blockchain/crypto infrastructure, and opportunities to lead technical initiatives and improve system reliability and performance.

I am a Senior Backend Engineer with 7+ years building high-load, low-latency distributed systems across exchange, settlement, blockchain, and platform infrastructure. I focus on concurrency, performance-critical system design, and reliability at scale.

I have hands-on experience designing and operating real-time data pipelines, execution and settlement engines, protocol-level systems, and custody solutions, and I have shipped production smart contract ecosystems and secure settlement engines with mainnet deployments. I led technical teams, owned full lifecycles from vendor negotiations to deployment, and drove security audits and integrations.

My technical toolkit includes Rust, Scala, Go, Java, Python, C++, C#, AWS, Docker, Kubernetes, Pulsar, Kafka, PostgreSQL, and RocksDB, and I bring deep domain expertise in market data, orderbook processing, DeFi mechanics, and MPC/cryptographic modules.
