Summary
Backend and platform engineer with 6 years shipping production-grade systems at American Express, Goldman Sachs and BlackRock, plus founding-engineer and lead roles across four live products. I build trading infrastructure, real-time data pipelines at scale, on-chain systems and enterprise platforms in Rust, Go and Java — and I work AI-native with Claude Code, Cursor and Codex to move from spec to reviewed production code faster.
Core Expertise
- Trading & market infrastructure — order books, perpetuals matching, funding and liquidations; built engines sustaining 60 orders/second and a DEX across 20+ markets.
- Real-time data at scale — 10M+ events/day in Rust over NATS JetStream with exactly-once delivery, into ClickHouse at 490M+ rows.
- Event-driven backend — Java / Spring Boot microservices on Kafka, event sourcing, Spark/Hadoop and AWS-native async flows.
- On-chain engineering — Solidity contracts, ERC-4626 vaults, Pyth oracles, on-chain collateral/PnL and Quorum tokenization.
- Enterprise platform delivery — dual-database migration frameworks at 99.9% consistency, SAP integration and multi-bank maker/checker workflows.
