What I'm looking for

I seek senior roles where I can lead OT/SCADA architecture, improve security and reliability, drive cost-saving automation projects, and mentor technical teams in an operationally focused organization.

I am a Senior Operations Technical and Industrial Automation Consultant with extensive experience in SCADA systems, field data acquisition, and OT architecture within the oil & gas sector.

I have led large-scale automation projects, migrations, and platform selections, delivering feasibility studies, technical specifications, and implementation strategies for downstream and upstream energy clients.

My work includes architecting PAD-level I/O and controller standards, separating OT/IT per Purdue model, and implementing secure point-to-point SD-WAN/VSAT solutions that produced substantial annual savings.

I combine hands-on technical proficiency with leadership, vendor and contractor management, and a focus on security standards (NIST SP 800-82, ISA/IEC 62443) to improve operational performance and sustainment.
