@nayaraevangelista
Analytical professional (8+ years in Electrical/Reliability Engineering) leveraging proven problem-solving and KPI analysis skills for remote roles.
I am an Electrical Engineer and STEM professional with over 8 years of proven success in industrial maintenance, reliability engineering, and complex team leadership within major companies like VALE and Gerdau. My career has been defined by applying rigorous analytical methods and a data-driven mindset to solve mission-critical operational challenges.
My Core Achievements & Skills:
Operational Reliability: I led initiatives that significantly improved critical KPIs (MTTR/MTBF), notably increasing plant availability from 75% to 95% over three years at ATVOS.
Structured Problem-Solving: I am highly proficient in structured methodologies like RCM, FMEA, and RCA, which allows me to quickly identify root causes and implement lasting process improvements.
Technical Leadership: I managed multidisciplinary teams of up to 35 people, consistently aligning maintenance execution with high safety standards (NR-10, NR-12, NR-35) and operational KPIs, resulting in a 30% reduction in maintenance backlog at VALE.
Technical Content Management: I possess extensive experience reviewing, annotating, and standardizing technical content, maintenance plans, and work orders within CMMS systems like SAP PM, ensuring data integrity and effective process execution.
In 2025, I intentionally took a career break for a 5-month international immersion in the UK. This commitment successfully elevated my English skills and greatly enhanced my cross-cultural communication and adaptability skills, preparing me for the global remote market.
During this transition, I leveraged my attention to detail and analytical skills in freelance roles as a Data Annotator and Reviewer. I was quickly promoted to a Reviewer position due to the consistent high quality and accuracy of my digital outputs, confirming my ability to manage workloads independently and deliver precision results in a flexible, remote setting. I also contributed to AI model training projects, demonstrating technical curiosity and rapid learning of new digital tools and protocols.
I am actively seeking remote roles, such as Expert Network Consulting, specialized customer/technical support, or advanced data review/annotation, where my blend of deep analytical capability, engineering discipline, and professional communication skills can drive value for international teams.
