👋 Hello
I’m Josue Sanchez,
Based in Orlando Area, FL.
Every utility knows its substations are aging. Few can tell their board what to replace first, what it will cost, and why. I'm Josue Sanchez. I help utilities plan, prioritize, and execute substation and distribution investments, and I build Al tools that make engineering teams faster.

Investigated and resolved power quality complaints as a Certified Power Quality Professional (CPQ) — diagnosing voltage, flicker, and harmonic issues — and implemented corrective actions that measurably reduced customer service disruptions and complaint frequency.
Executed root cause analysis on a high-fault-frequency circuit, identified underlying design deficiencies, and implemented system changes that reduced protection operations to one of the lowest levels in the service territory.
Improved system reliability indices (SAIDI, CAIDI, SAIFI, MAIFI) through targeted feeder analysis, sectionalizing design improvements, and infrastructure upgrade recommendations.
Planned, designed, and project managed electrical infrastructure for critical and high-profile loads including hospitals and large commercial and industrial customers.
