What I'm looking for

I seek roles in renewable energy where I can lead technical project delivery, optimize processes, and apply data-driven solutions in a collaborative, sustainability-focused team.

I am a senior electrical engineer with a strong focus on renewable energy systems, combining technical depth with project coordination experience.

With over five years in renewable energy project roles, I have led tendering processes, developed technical proposals, and improved operational performance through data-driven approaches.

My achievements include optimizing bid workflows as an Electrical Tendering Coordinator, reducing documentation errors as a Product Engineer, and improving operational reliability through KPI standardization as a Data Analyst.

I am proactive, sustainability-driven, and experienced with tools such as MS Project, Excel, MATLAB, PVSyst, and SQL, ready to contribute to teams delivering impactful renewable energy projects.
