Nicholas Muthoki
> Systems Architect && Full Stack Engineer
I create practical and reliable systems where financial accuracy meets decentralized innovation.
I focus on building software that is trustworthy, understandable, and useful. My approach uses Domain Gates: systems that validate and protect data before it reaches the ledger, whether in PostgreSQL, Ethereum Smart Contracts or AI agent workflows.
