I build backend systems, Ethereum infrastructure, and developer tools, mostly in Rust and Python. Recent work includes Ethereum trading and builder infrastructure, agentic engineering workflows, and internal tooling for engineering teams.
Current focus
What I'm working on now
Recent work centers on Rust, Python, Ethereum infrastructure, developer tooling, and agentic engineering workflows.
Ethereum infrastructure
Trading systems, builder infrastructure, Solidity tooling, and practical protocol integrations.
Developer tools and automation
CLIs, monitoring surfaces, internal tools, and automation that make engineering work easier to operate.
Agentic engineering workflows
Practical workflows for using coding agents without losing track of state, review, ownership, and quality.

Teaching
Teaching as engineering communication
I have taught Python professionally since 2012, including courses for teams at Intel, Samsung, Microsoft, and startups. I still teach selectively, mainly for engineering teams that want practical Python depth, clearer internals, better testing habits, and production-minded design.
About
About
I am a senior software engineer with 20+ years of work across backend systems, product engineering, Ethereum infrastructure, developer tools, and teaching.
I care about systems that stay explainable under pressure: clear boundaries, useful tools, practical documentation, and code that leaves room for the next person.
