Renewable and Sustainable Energy Engineer

Indonesia
Message

I’m a renewable and sustainable energy engineer with experience in solar PV systems, renewable energy operations, technical project support, and data analysis across Indonesia and Australia. I combine hands-on system design thinking with structured operational improvement to help renewable teams deliver reliably and at scale.

In my Business Development Analyst role, I monitored and managed SLA performance for risk assessment, engineering, and contract processes across 60+ renewable energy projects. I also evaluated and improved renewable energy credit assessment processes through data review, while managing Renewable Energy Certificate (REC) registration and issuance records for over 120 solar assets. I developed SOPs, workflows, and process maps to improve operational efficiency and clarity for stakeholders.

As a Jr. Product Solutions Engineer at Clenergy, I managed technical assessments and support for more than 2,200 solar PV mounting projects monthly. I analyzed project requirements to provide technical recommendations, supported structural engineers and sales account managers through calculations and proposal reviews, and led AI chatbot technical support implementation to improve customer response efficiency.

My foundation includes designing residential solar PV systems (panels, inverters, and batteries) and analyzing costs for 15 customers as a Solar PV Engineering Intern. Through research and engineering internships, I built strong habits in energy efficiency regulation analysis and electricity/energy-saving comparisons across HVAC and boiler systems. I’m especially interested in solar forecasting, energy storage systems, data automation, and energy management applications.
