Water Resources, GIS & Remote sensing specialist
Dear Eugene Water Electric Boar Hiring Manager:
I am excited to apply for the position of GIS Analyst II at your company. My working knowledge in hydrological and ecological modeling, field data collection, data analysis (managing advanced GIS, SQL database, and learning algorithms), programming skills, along with strong analytical, problem-solving and reporting results make me a great fit for this position. I am very enthusiastic about the opportunity to use my skills and abilities to help support the Eugene Water Electric Board (EWEB) team and contribute creative and innovative analysis techniques.

Enthusiastic, self-motivated, and results-oriented professional in Water Resources, Geographic Information Science (GIS) and Machine Learning, with 7+ years experience in geospatial and statistical analysis as well as flow and water quality modeling. Well-versed in quantitative analytical research, employing ArcGIS, SWAT, and R. Rich experience managing multiple databases and working on multiple projects simultaneously. Expertise in advance GIS, wetland delineation, land use and land cover (LULC) change and time series analysis employing learning techniques (Machine & Deep learning). Experience in web-mapping and developing Decision Support Systems (DSS) such as WRESOTRE (http://wrestore.oregonstate.edu/). Education:
• PhD. Civil Engineering – Water Resources, Oregon State University (OSU), Corvallis, OR, USA.
(2017 – 2021). My research involved hydrological and water quality modeling including BMP plans, agricultural features, using software in the GIS environment. In addition, stakeholders’ decision making for BMP plans were evaluated through the WRESTORE decision support system.
• M.Sc. Civil Engineering – Water Resources, Oregon State University (OSU), Corvallis, OR, USA.
(2014 – 2016). My work involved hydrological, water quality and bird habitat modeling including potential wetlands, crop operation, and riparian features, using software in the GIS environment. In addition, it included the optimization of wetlands to maximize their benefits while minimizing costs.
• National University of San Cristobal of Huamanga (UNSCH), Ayacucho, Peru. (1992 – 1997) Bachelor (Hons) in Civil Engineering.
Relevant Work Experience:
• Research Assistant in nature-based modeling to mitigate climate change effects. Oregon State Univ.
(Jan. 2017 – Dec. 2021)
I conducted hydrological and water quality modeling for Dairy McKay Watershed in Oregon and Eagle Creek Watershed in Indiana, involving BMPs like riparian vegetation and wetland restoration, crop operation, filter strips and others, for flow and ecological benefits (peak flow, sediment, nitrate, and stream temperature reduction). Modeling involved processing geospatial data such as water rights, land use and land cover (LULC), Soil data from SSURGO, DEM, PRISM-data, Remote Sensing Data (RSD), among others. Results were arranged in plans that were presented to stakeholders in reports, face-to-face meetings, and through the WRESTORE Decision Support System (DSS) (http://wrestore.oregonstate.edu/model_ecw/g2c.php), I developed. Stakeholder preferences for plans were evaluated using statistical tests. In addition, stream temperature was evaluated as an indicator of water quality for current and future scenarios. These results were compared with machine learning techniques (XGBoost, MLP, and CNN)
• Research Assistant in wetland restoration modeling for attaining flood, water quality and bird habitat benefits. Oregon State Univ. (Set. 2014 – Dec. 2016) I performed hydrological, water quality, and ecological modeling of the Big and Eagle Creek Watershed in Indiana. Potential wetlands were delineated from satellite images and included in the model as nature-based measures to reduce flood peaks, improve water quality and biodiversity. BMPs such as filter strip, crop rotation, and land use and land cover changes were also included in the modeling. Due to the large amount of data to process, the processes were automated using model builder, Python, and Java. Results were mapped and presented to stakeholders via the WRESTORE DSS. In addition, multi-objective optimization was performed to maximize wetland benefits and minimize costs
• Field Engineer. NV Building Company Inc, Lima, Peru (Jan. 2008 – March 2013) In this job, I worked inspecting various projects related to dams, hydraulic structures, irrigation systems, among others. This inspection involved work such as field measurements, field data processing, preparing reports for my supervisor, and engineering advice for future designs.
• Consultant Engineer. Peru Department of Agriculture (March 2005 – Dec. 2007). I worked providing engineering advise and technical solutions on different projects related to water management, soil conservation practices. Main clients were private agencies. Professional Skills Training
• Advanced GIS and remote sensing, handling tools such as ArcGIS, ArcGIS Pro, ArcGIS online, ENVI, GIS programming with Python (ArcPy), and model builder, and geospatial data Landsat, MODIS.
• Rich experience in modeling land use and conservation practices (wetlands, filter strips, crop operation, and others) to help mitigate watershed issues using SWAT, MODFLOW, HEC-RAS, HEC-HMS.
• Database Management: SQL, MySQL, Toad, Json, GeoJson, Access.
• Programming skills in Python, Fortran (SWAT code), Java, employing Git version control.
• Machine learning modeling: XGBoost, SVM, MLP, CNN, ML for time series, among others using Scikit- learn, Keras, TensorFlow in Colab and other tools.
• Advanced knowledge in Statistics and Data Analysis handling multivariate analysis using open source software such as R, Jamovi, Octave (Matlab), and Python. Software development, programming and web tools
