JOIN ME IN MY JOURNEY

On Becoming a

Network & Cybersecurity Engineer

Welcome to a space where passion meets purpose—where every ping, packet, and protocol brings me one step closer to becoming a network and cybersecurity engineer. I’m just getting started, and this blog is my open journal, documenting every lesson, challenge, and breakthrough along the way. Whether you're a fellow beginner, a curious explorer, or a seasoned pro, I invite you to join me in this journey. Let’s learn, build, and grow together—one command line at a time

Introduction In this project, I completed a full ortho mapping workflow in ArcGIS Pro to create accurate satellite imagery products. The goal was to correct geometric distortion in raw satellite images so they can be reliably used for mapping, analysis, and measurement. This workflow included creating an ortho mapping workspace, performing block adjustment, adding ground control points, generating a digital

Most people think GIS is about making maps. In reality, the most valuable GIS work happens when spatial analysis supports real decisions. This lab focused on a practical problem faced by many communities: how to identify open-space parcels inside flood-prone areas that may qualify for FEMA Community Rating System (CRS) credits and potentially reduce flood insurance costs. What makes this

Introduction In a recent lab exercise, I worked with GeoDa, developed by the University of Chicago Center for Spatial Data Science, to examine spatial structure in geographic data. The objective was not simply to map values, but to determine whether patterns were statistically clustered, dispersed, or random. A map shows distribution. Spatial analysis tests whether that distribution has structure. What

In this lab for REM-617-01: Image Analysis & Information Extraction, we performed image manipulation and atmospheric correction using a Landsat ETM+ scene in ENVI. The assignment required stacking spectral bands, interpreting RGB composites, creating a Region of Interest (ROI), building a mask, computing statistics, and applying Dark Object Subtraction (DOS). The objective was to move from raw satellite data to

Abstract This study examines the relationship between median rent in 2008 and the percentage of households with children in 2008 across New York City sub-boroughs. Exploratory spatial data analysis was conducted using GeoDa to assess the distribution of data, identify outliers, and evaluate statistical relationships among variables. Results indicate that median rent is positively skewed, while the percentage of households

Abstract This study examines the spatial distribution of Airbnb listings in Albany, New York, and evaluates their statistical clustering using the Getis-Ord Gi* local indicator of spatial association. Listing locations were aggregated into 8,000-foot hexagonal areal units to address spatial structure and mitigate point-level noise. A fixed distance band of 12,000 feet with row-standardized spatial weights was applied to identify

Here we go again, dressed up as responsibility. This week, The Manila Times reported that the Philippines is considering mandatory social media user verification to curb abuse. The pitch is neat and comforting. Order over chaos. Safety over noise. Names over anonymity. The subtext is even clearer: if everyone can be identified, everyone can be managed. That is not about

Somewhere inside Malacañang Palace, there is a comforting belief that corruption can be outsmarted by software. Not confronted. Not dismantled. Outcoded. Just add blockchain, say transparency a few times, roll out a pilot, and suddenly decades of theft, patronage, and selective justice politely excuse themselves and leave. It never works that way, but we pretend it does. Yes, Filipinos might
