Systems Engineering
Rail systems testing, field integration, turnover readiness, stakeholder coordination
Hi, I'm @nautxx,
17+ years building with a sharp eye for quality, usability, and aesthetics across construction engineering, field systems, service operations, and software.
From major infrastructure projects to automation-backed businesses, I turn messy problems into working systems: inspection workflows, testing processes, SOPs, customer operations, custom builds, and tools built end-to-end that last.
At Codenauts, I turned repeatable problems into repeatable systems — cleaner workflows, documented processes, automation, and self-service support for customers and teams.
Build it well. Make it useful. Make it last.
This still feels like day one. Ready for what’s next.
17+ years building reliable systems across infrastructure → quality → field operations → automation → software, translating complex real-world work into clear processes, durable tools, and measurable outcomes.
