Solar ProducƟon Predictor

Built a solar producƟon predictor to quickly and economically get bankable solar producƟons.

Managed measured solar producƟon data from over 500 different sites with more than 100 features each. Trained and opƟmized mulƟple machine learning models (Linear Regression, Random Forest and XGBoost).

The top performing models achieved results with +/-10% error based on benchmark with the measured data, significantly surpassing the tradiƟonal predicƟon method. This resulted in an esƟmated savings of about $120,000 and geƫng the results quicker for the clients by reducing over 70 less important features. Energy Savings Detector

Led a team to analyze (Python/SAS) large volumes of historical energy consumpƟon data (Time Series), spanning over 1.0 million premises to idenƟfy energy consumpƟon paƩerns, trends and detect anomalies.

OpƟmized building energy consumpƟon for over 22,000 premises through energy efficiency measures like smart lighƟng control and HVAC system etc. Created Energy Savings Detector to calculate and visualize the energy savings for different measures (Matplotlib/Power BI).

Found that energy efficiency measures like AC Tune-up and Duct TesƟng/Sealing offered the most energy savings and helped to secure esƟmated regulatory rebates of $560,000 for uƟlity companies. DNV GL USA INC Katy, TX

Senior Engineer Project Manager 09/2009 - 04/2020

Finite Element Analysis Global and hydrodynamic finite element analysis of offshore structures by use of GENIE and ABAQUS to assess strength capacity of offshore structures. Appointed to be project manager (PMP cerƟfied) and fully responsible for various oil and gas projects. PROJECTS

Employee Churn Predictor 03/2023 - 06/2023

Developed a model to predict employees who are likely to leave a technology company.

Integrated different types of data, such as employee age, and monthly income etc. for over 23,000 employees. Reduced over 33 features and integrated new interacƟve ones. The chosen Random Forest Classifier model had good performance, achieving a recall score of 0.93 and F1 score of 0.94.

Deployed the model on AWS EC2 with Streamlit for real-Ɵme monitoring, aiding in employee retenƟon strategies. EDUCATION
