Professional profile · Oil & Gas
Sabit Trumov
Senior Materials & MRO Leader · Oil & Gas
Twenty years in the oil & gas industry: from CMMS Engineer to Field Materials Superintendent. I connect technical requirements, SAP data, stock reality and supply constraints into decisions that are practical, traceable and ready for execution.

01Professional identity
What I bring to the table
I connect field reality, SAP data, technical requirements and supply constraints, then turn them into a decision that can be explained, audited and executed.
I work where maintenance demand, materials, inventory, procurement and operational risk meet. My value is not only in processing material requirements. It is in turning fragmented signals into decisions, workflows and systems that people can trust. My career progressed from CMMS and spare-parts engineering to superintendent leadership, plant-wide inventory responsibility, preservation governance, procurement support, reporting and digital workflow design.

04Leadership and teamwork
How I lead
Leadership in practice- Evidence before assumption
Use the available signals before adding demand, cost or risk.
- Ownership over activity
A task is finished when the outcome is clear, not when it moved.
- System over symptom
Recurring problems deserve a rule, a workflow or a governance fix.
- Respect with standards
Firm on quality and responsibility, without losing respect for people.
