Results-driven Senior Electrical and Renewable Energy Engineer with over 12 years of experience specializing in the development, commissioning, and utility-scale operations of Solar PV and BESS projects (10MW to 500MW) across the US and LATAM. Proven track record as a Team Lead and Deputy, expert in battery degradation analytics, plant performance optimization (PR/Capacity testing in Solar PV and BESS), and transitioning BESS assets into self-perform O&M. Self-motivated, promoting team integration and innovative ways to work, supporter of balance between human well-being and professional life.
Work History
BESS Maintenance Engineer
1 Year 8 Months- Asset Performance & Degradation Evolution: Evaluate and model real-time BESS equipment health and battery aging curves, project accurate End-of-Life (EOL) scenarios to optimize multi-cycling strategies and preserve asset value.
- Self-Perform Transition: Standardized a comprehensive suite of Standard Operating Procedures (SOPs) and troubleshooting guides, enabling seamless transitions to self-perform maintenance for the BESS fleet.
- Engineering Coordination & Leadership: Act as the primary technical authority for utility-scale BESS sites (including BMS, inverters, HVAC, and auxiliary systems), coordinating field teams and technical services to minimize downtime. Lead identification and resolution of issues, working closely with on-site teams.
- Systemic Issue Resolution: Spearheaded cross-functional initiatives to diagnose and resolve chronic inverter issues, thermal derate, and SOC calibration and balancing gaps, enhancing overall fleet reliability and performance. Analyze and interpret technical data to assess BESS equipment health and recommend maintenance updates in collaboration with engineers and planners. Supporting BESS execution and planning teams in developing and reviewing maintenance plans.
Senior Solar Engineer, Center of Excellence
2 Years 10 Months- Team Leadership & Deputy Functions: Led the Solar Design Specialist team as Deputy, coordinating project execution workflows, aligning technical tasks, and onboarding/training over 20 O&M engineers to scale internal capabilities.
- Due Diligence & Energy Yield: Directed comprehensive Energy Yield Assessments (EYA), Back-cast studies, and technical due diligence for utility-scale solar portfolios, supporting design criteria during RFP stages. Strong background of project development, participating from conceptual design and reviewing and validating 10%, 30%, 60%, 90% and IFC design packages. Participated of RFP processes, aligning technical requirements with contractor capabilities.
- Performance Testing & Standards: Authored internal PV plant design standards and loss definitions; successfully led site teams through Performance Ratio (PR) and Capacity Tests to meet critical contract milestones for 3 PV plants in the USA. Oversaw site data collection, analysis, and installation reviews to ensure optimal PV plant performance.
Solar Resource Specialist
2 Years 7 Months- Yield Optimization & Layout Design: Engineered optimized solar plant layouts and resource models using PVSyst, yielding a 7% reduction in energy losses across major operational assets. Conducted solar resource and energy assessments for solar power plants, providing critical analysis for optimal performance. Created detailed solar power plant layouts ensuring efficient design and energy production.
- Commissioning & As-Built Verification: Conducted rigorous field inspections and validated "As-Built" data, identifying performance gaps between layout design and real-world generation to protect baseline revenue.
- Operational Performance enhance: Analyzed system losses and supported internal teams in evaluating Performance Ratios, enhancing operational efficiency. Reviewed and analyzed site measurements against performance data to identify and address energy production gaps.
Electrical Specialist Engineer
5 Years 5 Months- Engineering Design Collaboration: Design of electrical engineering for On & Off-Shore Oil and Gas, commercial and industrial facilities in low and medium voltage with the application of national and international electrical engineering design codes and standards (NEC, IEC, NOM, NFPA). Developed power generation prototypes utilizing renewable sources (primarily photovoltaic) for commercial applications, promoting sustainable energy solutions., including drafting of users manuals and training sessions for clients.
- Multidisciplinary Team Integration: Structured and integrated dedicated Renewable Energy teams, defining scopes and dynamics of teamwork.
Electrical Auxiliary Engineer
