About

Mechanical Engineer working on complex industrial projects in the semiconductor sector, currently serving as Engineering Coordinator at STMicroelectronics. I coordinate internal engineering teams and external design contractors, supporting tendering processes, engineering planning, and delivery of multidisciplinary infrastructure projects. My role focuses on aligning design priorities, managing engineering deliverables, and contributing to early-stage planning through cost, schedule, and material estimations for upcoming installation activities. I have also been involved in defining team KPIs and improving internal project processes, contributing to measurable improvements in schedule adherence and design cycle times. Previously, I worked as a Hook-Up Project Engineer within the same organization, supporting the execution of multidisciplinary installation packages (~€3M scope) in live semiconductor manufacturing environments, achieving ~98% schedule adherence across construction, commissioning, and start-up phases. This experience allowed me to work closely with contractors, vendors, and operations teams while ensuring alignment between engineering design and site execution. Earlier in my career, I gained EPC project exposure at Technip Energies, contributing to modularization studies, construction execution planning, and subcontractor technical assessments for large-scale Oil & Gas projects. My professional focus lies in project coordination, engineering execution, and process optimization, with a strong interest in developing further within Project Engineering and Project Management roles, where technical expertise, structured planning, and stakeholder coordination are key to successful project delivery.

    • Engineering Coordinator
      Nov 2025 - Present · 8 mos

      Coordinating internal design activities and external engineering contractors within complex semiconductor infrastructure projects. My role focuses on aligning engineering priorities, managing contractor interfaces, and ensuring that design deliverables are developed in line with project timelines and operational needs. Key responsibilities include defining team KPIs and performance metrics, managing tender processes for design and installation packages, and developing assignment scenarios for installation contracts. I also contribute to early project planning through material, schedule, and cost estimations for upcoming installation activities. Additionally, I have worked on improving internal processes related to tendering and project delivery, contributing to a 23% increase in schedule adherence and measurable reductions in design cycle times. To support transparency and decision-making, I developed PowerBI dashboards and activity tracking tools providing reporting at operational, tactical, and management levels.
