About

Five years turning specs into running plants.

I turn process intent into control systems that survive construction. Five years across fab and minerals plants — three capital projects, ~30,000 I/O specified, 400+ RFIs and 200+ submittals closed without slipping schedule.

Design intent → construction

P&IDs, loop sheets, wiring, and narratives that survive the field with traceable revision discipline.

Cross-discipline alignment

Keeps Process, Electrical, Mechanical, and Piping coherent so the plant is one design — not five.

Field-side problem solver

Support During Construction: resolve issues, close RFIs, confirm commissioning matches intent.

Cross-team coordinator

Primary bridge between distributed engineering teams — aligning deliverables and priorities across time zones.

Skills & Toolchain

Experience

Five years, four roles, four disciplines coordinated.

From submittal reviews to design package ownership — each role added a new dimension to how I think about controls in a plant.

  1. Senior I&C Engineer

    Exyte U.S. Inc.Chandler, AZ
    Feb 2026 — Present
    • Lead I&C design for large-scale semiconductor and industrial projects — drawings, specs, and system architectures delivered as constructible packages.
    • Own the design/trend package: oversee deliverable updates, manage revisions, and keep process, electrical, mechanical, and piping disciplines aligned.
    • Provide Support During Construction (SDC): guide field teams, resolve installation issues, and confirm commissioning matches design intent.
    • Drive submittal reviews for instrumentation, control panels, and automation — issuing clear, traceable comments that hold vendors to spec.
    • Manage RFIs with detailed engineering clarifications that close design conflicts and protect schedule integrity.

  2. I&C Engineer

    Exyte IndiaIndia (cross-site with US)
    May 2025 — Jan 2026
    • Completed instrumentation & controls submittal reviews ensuring vendor packages met project specs, standards, and operational requirements.
    • Reviewed and updated P&IDs, loop sheets, wiring diagrams, and control narratives to support construction sequencing and field changes.
    • Primary coordinator between India and US engineering teams — aligning deliverables, construction support, and project priorities across time zones.
    • Led technical discussions that drove timely closure of submittals, RFIs, and construction-phase queries between global teams.

  3. Technology Systems Engineer III

    Exyte U.S. Inc.Chandler, AZ
    Jun 2022 — Apr 2024
    • Developed engineering solutions, drawings, and specifications for instrumentation and control systems in the semiconductor industry.
    • Coordinated I&C design with Process, Electrical, Piping, and Mechanical to ensure a coherent plant-wide design.
    • Partnered with clients to develop system architecture for a functional site communications network supporting the control systems.

  4. I&C Engineer II

    M3 Engineering and TechnologiesChandler, AZ
    Sep 2021 — Jun 2022
    • Developed instrument indexes, I&C specifications, spec forms, logic diagrams, instrument plans, and installation details for timely plant construction.
    • Supported procurement by issuing Engineering Requisitions and performing technical analysis to ensure correct equipment was ordered.
