Completed Online GIS Certificate course at the University of West FL. Accepted a new job position in a collaborative and diverse work environment at Collier County Property Appraisers Office. My new job responsibilities now include GIS tasks centered around entry to intermediate level cadastral GIS mapping activities involving recorded deed data to verify, update, or create new parcel information to support a cadastral dataset of various layers that support a county-wide tax roll. I'm looking forward to this new learning experience and opportunity to widen my GIS skills to include interpreting official recorded data and using COGO tools to examine and traverse recorded metes and bounds legal descriptions related to tax parcels.

August 2019 - December 2020
Sr. Operational Analyst
BCC Collier County - Growth Management Division (GMD), FL

Continually learning and applying GIS in the Planning and Regulatory Government work-space is my current routine. I'm planning to graduate from the Online GIS Certificate course at the University of West FL. I also continue to practice database and web programming skills as I learn to adapt to Esri's new program called ArcGIS-Pro and the new flavor of arcpy, which is now using python-3. I also continue to explore cartography using ArcGIS Pro, which is showcased in a new Esri MOOC dedicated to learning Cartography using ArcGIS Pro. I'm looking forward to learning and using this new 64bit GIS software. I just purchased a new video card that better supports graphical needs of ArcGIS-Pro and hopefully, the learning experience will be better with a CUDA core enabled video card.

January 2016 - August 2019
Sr. Programmer Analyst
BCC Collier County - Growth Management Division (GMD), FL

Another reorganization in the Growth Management Department introduced me to the Planning and Regulatory workspace, which was familiar to me growing up in a family that worked and lived in the Building and Construction industry. Building footprints and property boundaries were not new to me. I mainly supported the building review process and an agency application called CityView. I managed the Enterprise Data Engine and the integration of GIS services required by CityView to support the Building Review Module. I also learned to perform GIS reviews, whcih involved reading blueprint, which was nothing new. I grew up reading blueprint along side my Grandfather, Father, and Uncle. What was new to me was the permitting process, regulatory review, environmental planning, and zoning aspects of building. Site development planning was an interesting experience. And in the realm of GIS, was starting to apply the GIS corriculm learned via an Online GIS course at the University of West FL.

October 2014 - January 2016
Sr. Operations Analyst
BCC Collier County - GMD Transportation Division, F

A Transportation department reorganization opened the door for an Application Administrator for an agency asset management system called Cartograph, which included GIS integration for field crews to collect asset information using Trimble devices. I was now involved in maintaining new and existing roadway data that allowed me to continue my map making skills for internal and public audiences.

March 2013 - October 2014
Wastewater Sr. Technical Specialist
BCC Collier County - Public Utility Division (PUD), FL

My main work focus was finally GIS. I worked on a project to convert a Wastewater ArcGIS 9.3 infrastructure to ArcGIS 10.0 and as a result, started to be the dedicated ArcSDE administrator of the new version 10.0 spatial data engine (SDE). Making maps with data being collected and maintained began a learning process into Cartography that continues today with Esri's new flagship program, ArcGIS Pro, which is a better map making experience for me as compared to using ArcMap for Cartography tasks.

January 2011 - March 2013
Application Analyst
BCC Collier County - Information Technology (IT), FL

Main focus was Application & Database support and delivering services, products, and customer exspectations with the help of new learned skills in Project Management, which I acquired when studing for my Professional PMI Certification (PMP), which I acquired in 2009. My PMP Certificate # is 1634944. Some of my projects involved GIS related deliverables which allowed me to continue exploring GIS via ArcObjects and making web maps with a now old out-dated Flex technology. I was also introduce the ArcGIS for Developers website and continue today to participate with today's tutorials.

September 2009 - January 2011
Programmer Analyst
BCC Collier County - Information Technology (IT), FL

Although my main focus was related to Microsoft related technologies such as converting ColdFusion websites to ASP.NET, Sharepoint, SQL Server Reporting Services, backend Sql Server DB support, an introduction course on ArcObjects with VBA at USF in Tampa was when I started learning about GIS.

GIS-4043 Introduction to GIS

This map involved some spatial analysis where I examined locations, attributes, and relationships of features in spatial data through overlay and other analytical techniques to obtain knowledge of campsites near other features (roads, lakes, and rivers) that might be helpful when selecting a campsite. Proximity Analysis answers questions like what campsite features are near other features, such as streets, lakes, and rivers. The outcome of proximity analysis is the generation of new information as the result of taking one or more actions on a set of features described by some criteria. I put this into action when obtaining useful camping information. GIS overlay tools combine features and attributes from multiple layers to create new information. Both the geometries of the features and the attributes of those features are carried through the overlay process.

GIS 3015 Cartographic Skills

In this class, I learned to graphically communicate via artistry, symbols, fonts (typography), and balancing all primary & secondary (figure-ground) objects in a pleasing way based on the map purpose and intended audience. In this map example, I applied a few design principles (simplicity, context appropriateness, and pleasing appearance) and several aspects of map composition (visual balance, focus of attention), which is the arangement or organizaition of map elements.

GIS 4102 GIS Programming

I've used this model for many years as an Enterprise GIS GeoDatabase administrator. It's an Esri good practice for maintaining a geodatabase. As a geodatabase is edited over time, the adds and deletes tables increase in size which can negatively impact database performance. I've also exported this model as a Python script and executed it as a nightly task by creating a Windows scheduled task. Automating various geoprocessing tools in a script during available network maintenance windows will help ensure your GIS customers have a responsive experience.

GIS-4035 Remote Sensing & Photo Interpretation

This statis map deals with Remote Sensing. It is the result of learning the basics of ERDAS Imagine and properties of Electromagnetic Radiation (EMR), the source of energy recorded and analyzed in all types of remote sensing. ArcMap 10.3 was used to display the output of preprocessing (subset) an advanced Very High Resolution Radiometer (AVHRR) satellite image using ERDAS.

GIS-4035 Remote Sensing & Photo Interpretation

This statis map deals with Photo Interpretaton. The image reminds me how-to use various recognition elements to visually interpret aerial photographs by using the tone and texture of aerial photographs. Tone describes the brightness or darkness of an area. Texture deals with how smooth or rough the surface appears.

GIS-4930 Special Topics in GIS

This is a story map journal is made up of different types of slides (graphic/image, map, web map, video, etc). Each slide is a navigational component that has two parts: a descriptive part and visual part, which is the main visual part of the slide component. It's a great way to capture you map user's attention.

GIS-4944 Internship

During this semester I continued to apply learned GIS skills at work, focus on learning ArcGIS Pro, and build a web-enabled version of both a profile and resume. I experimented with various types of templates that I discovered on the internet. This website that you are currently viewing is my work-in-process profile, which contains links to a web version of my resume and a downloadable version of my resume. Of all the templates I created, this one works the best for a shared low-budget student hosting account through sitegrounding.
