About

I focus on backend systems, infrastructure, and performance across AI, Blockchain, Fintech, AdTech, and eCommerce.

I've worked on AI platforms that help turn ideas into working software, including MCP servers and the systems required to run them reliably, and I've built and operated core systems in the Ethereum ecosystem, including MEV builders, searchers, custom relays, and Layer 2 solutions on the OP Stack.

My background also includes full payment systems, financial data pipelines, AdTech tooling, analytics dashboards, and eCommerce platforms with integrated NFT marketplace functionality.

I'm always interested in new domains, complex systems, and challenging engineering problems.
