I've built everything from automation scripts and custom formulas to add-ins, ribbons, and interactive KPI dashboards. A big part of my work involves cleaning, reshaping, and consolidating large volumes of exported data so it's actually usable. I also collaborate on open-source projects on GitHub, so I'm comfortable reading other people's code and improving it. Clients often tell me I come up with solutions they didn't know they needed. I attribute that to my engineering background and a mindset built around analytical thinking, systems thinking, and problem-solving. I'm passionate about building tools that people actually find useful. Clear communication matters a lot to me. I tend to ask detailed questions upfront to fully understand the problem, to save time and frustration later. When you reach out, you can expect a response within 24 hours, a solid understanding of your needs, and a clear plan with realistic timelines. I'm comfortable working on both fixed-price and hourly projects, depending on what makes the most sense for the job. Thanks for reading!

When your spatial data is messy, your workflows are manual, or your deliverables aren't decision-ready — that's where I come in. I'm a Civil and GIS Engineer. That combination matters: I don't just map your infrastructure, I understand it. My analysis is grounded in engineering logic, which means outputs that hold up in planning, design, reporting, and field use — not just visually clean maps. My project history spans post-conflict infrastructure damage assessment with UN-Habitat Lebanon, national-scale digital twin QA/QC facilitation in Saudi Arabia, multi-epoch LiDAR elevation analysis for tidal marsh restoration in California, seismic risk and building vulnerability assessment for a peer-reviewed MDPI Remote Sensing publication, solid waste routing GIS for Lebanese municipalities, end-to-end parcel screening automation across US counties using ArcGIS REST APIs, and AI-based change detection training using deep learning and open-source tools. I have also placed in ESRI GIS competitions. I work across the full GIS project lifecycle — raw data intake, quality validation, spatial analysis, workflow automation, and final client-ready deliverables. My clients include environmental consultancies, engineering firms, municipalities, humanitarian organizations, and research institutions. Available for short-term projects, long-term contracts, and ongoing retainer engagements.

𝗛𝗲𝗹𝗹𝗼! I'm Kim, a serial entrepreneur turned Business & Strategy Consultant with 10+ years of experience helping startups, small businesses, and Fortune 100s like Disney and Boeing thrive. The knowledge & expertise I've gained from experience is fortified by Lean Six Sigma certifications, a Psychological Science degree, and an MBA from USC Marshall (a top-20 business school). 𝗕𝗔𝗖𝗞𝗚𝗥𝗢𝗨𝗡𝗗: My mother was an entrepreneur, so like a fish in water, I've been surrounded by business my entire life. She founded a snack food manufacturer when I was 5, and it grew alongside me like a sibling. After her unexpected passing, I became the company's CEO and joined forces with my human siblings to run it. That remains the most stressful and scariest year of my professional and personal life, but the lessons afforded to me during childhood and the support of an awe-inspiring team empowered me to succeed its trials by fire. In my first year as CEO, revenue increased by 20% and profitability increased by 36%. We doubled within a few years and steadily grew until receiving a buy-out offer that, after some negotiation, we couldn't refuse. I attribute those experiences to the consultant I've become and my ability to connect with clients. I'm intimately familiar with how overwhelming running a business can be, and I'm passionate about leveraging the knowledge and expertise I've accumulated to empower entrepreneurs in similar ways. 𝗛𝗢𝗪 𝗜 𝗖𝗔𝗡 𝗛𝗘𝗟𝗣: I bring a unique blend of practical knowledge, strategic thinking, business acumen, and technical skills to the table. I specialize in data-driven strategy development, which frequently culminates in projects including comprehensive research & data analysis, business plan writing & development, growth & marketing strategies, and financial analysis & planning. Furthermore, my network of industry experts and professionals enables me to provide clients with access to additional resources and support. 𝗛𝗜𝗚𝗛𝗟𝗜𝗚𝗛𝗧𝗘𝗗 𝗖𝗟𝗜𝗘𝗡𝗧 𝗥𝗘𝗦𝗨𝗟𝗧𝗦 • Secured seven-figure funding from investors, banks, and SBA programs. • Boosted IT service provider's growth rate from 3% to 16% in 6 months. • Increased an HVAC company's net income by 33% despite a 7% revenue decline. • Grew a supplement company’s EBITDA 16% by aligning corporate & financial strategies. • Outsold 97.9% of sellers on the $2.3 billion platform Etsy within a drinkware brand’s first year by developing scalable go-to-market and operational strategies. • Drove 385% growth in hyper-competitive entertainment industry as fractional CEO, establishing a renowned 27,000 sq. ft. multimedia studio. • Increased YouTube channel's 90-day impressions by 46%, views by 126%, and click-through rate by 1.9%. 𝗟𝗲𝘁'𝘀 𝗱𝗶𝘀𝗰𝘂𝘀𝘀 how I can leverage my lifetime of experience, formal education, and incredible network to take your business to the next level. I know that hiring a freelancer is an important decision, and I'm happy to provide more information and answer any questions you may have. I’m here to help and just a message away!

You don't just want a "black box" model. You want answers you can trust. I don't just build models; I build deployed, explainable, and reliable data science tools. I specialize in the complete end-to-end ML pipeline, from a messy CSV file to a live, interactive Streamlit app that provides your team with actionable, data-driven insights. My process focuses on Explainable AI (XAI). A model that's 99% accurate is useless if you can't understand why it's making its decisions. I use tools like SHAP to open the "black box" and show you exactly which features are driving your predictions. My 100% Job Success Score isn't just a number; it's my commitment to professionalism, clear communication, and delivering a polished, robust final product. My project works has given me deep, hands-on experience in the complete data science lifecycle. I am ready to apply these skills to your business. My Core Skills & Deliverables When you hire me, you are hiring a multi-faceted problem-solver. Here is the menu of my capabilities and the tangible products I deliver. Skills (The "How") Analysis & Strategy: -Data Auditing: I find the "lies" in your data—contradictory rows, logical fallacies, and hidden biases that will poison your model. -Deep EDA: I use correlation heatmaps and distribution plots to find and solve hidden problems like high multicollinearity. -Feature Engineering: I transform weak, redundant, or confusing features into new, powerful signals (e.g., combining Sales and Time into Sales_Velocity) that give your model a clear path to success. Modeling & Engineering: -Model "Bake-Offs": I test multiple models (e.g., Logistic Regression vs. Random Forest vs. XGBoost) to prove which one is actually the best tool for your specific problem. -Optimization for Imbalance: I am an expert in handling imbalanced datasets (like fraud or churn) by tuning decision thresholds using Precision-Recall Curves to catch rare, critical events. -Pipelines: I build robust, production-ready scikit-learn Pipelines that bundle all preprocessing and modeling into one clean, deployable object. Deliverables (The "What You Get") -A Deployed, Interactive Streamlit Web App A live, user-friendly application that your team can actually use to get real-time predictions. -A Full Data Analysis & EDA Report A comprehensive Jupyter Notebook or Medium article that tells the story of your data, explaining all insights and the "why" behind my design choices. -Model Explainability (XAI) Reports Clear, simple SHAP plots (waterfalls, bar charts) that answer the "why" and build trust in the model's decisions, allowing you to take confident action. -A Clean, Version-Pinned Deployment Kit A production-ready requirements.txt or environment.yml file. This is the "blueprint" that guarantees your app will work perfectly on a server without the AttributeError crashes that plague beginner projects. Why Choose Me? 1. End-to-End Builder, Not Just an Analyst. You get a tangible, deployed, and usable tool, not just a theoretical notebook. I am a problem-solver who can handle the entire process from data cleaning to app deployment. 2. Explainability & Trust Expert. My specialty is opening the "black box." I don't just give you a score; I give you the reason, using SHAP to build trust and deliver actionable insights. 3. Proven Professionalism & Reliability. As a freelancer with a 100% Job Success Score, I am a reliable, communicative, and organized professional. I deliver polished, documented, and robust solutions on time. Ready to Work Together? Do you have complex data that needs to be transformed into actionable insights? Or perhaps you have a model stuck in a Jupyter Notebook that your team can't actually use? I'm here to help. I specialize in turning data problems into deployed, automated solutions. Send me a message about your project. Let's work together to turn your data into your most valuable asset. You have data. I build the tools to turn it into decisions. Let's talk.

Leaked content, impersonation, and unauthorized distribution can damage your reputation, audience trust, and revenue in a matter of hours. For the past 5+ years, I’ve helped talent agencies, digital brands, and online platforms identify, investigate, and remove unauthorized content across Google search results, social media platforms, forums, and hosting providers. I don't just send automated templates. My experience comes from managing large-scale enforcement operations, where I personally processed more than 700,000 high-risk URLs per year while maintaining a 98% accuracy rate under strict deadlines. What I Help With ▪ DMCA Takedowns & Content Removal Identify and investigate leaked or unauthorized content across search engines, social platforms, forums, and third-party websites. Submit DMCA notices and manage platform specific reporting processes. Coordinate directly with hosting providers and registrars when standard removal channels fail. Reduce the visibility of infringing content in Google search results (SERPs). ▪ Impersonation & Content Abuse Investigations Detect fake profiles, rogue domains, and unauthorized use of brand assets. Investigate distribution networks and coordinated abuse patterns to identify the source of unauthorized content. Use OSINT techniques to gather clear, actionable evidence for escalations and enforcement actions. ▪ Large-Scale Enforcement Operations Process high volumes of URLs, images, and digital assets efficiently without sacrificing accuracy. Handle complex removal cases, counter notices, and disputed takedowns. Maintain structured documentation and organized workflows to keep investigations moving forward. How I Work Automated tools and scrapers are useful for scale, but they are often blind to context. They can miss the difference between a legitimate use case and a real violation, and in content enforcement, mistakes can result in financial loss, reputational damage, and unnecessary disruption. My approach combines efficient investigation workflows with careful human review. Every enforcement action is reviewed and validated before escalation. When standard reporting methods fail, I identify the relevant hosting providers, registrars, and compliance teams to pursue manual resolution pathways. Why Clients Hire Me They need someone who can take ownership of investigations, organize findings, and move cases forward without constant oversight. I understand how unauthorized content spreads across platforms, how to trace hidden distribution points, and how to act quickly before exposure becomes a larger problem. If your agency, platform, or brand is dealing with leaked content, impersonation, copyright infringement, or platform abuse, let's discuss your situation and identify the fastest path to resolution.

I have a Bachelor's Degree in Psychology from De La Salle University-Manila and I finished rank 9 from the Board Licensure Examination for Psychometrician back in 2019. I've been working with Marketing Consultants as a Data Analyst for 3 years and can provide different kinds of analytics reports depending on the business need. I can do statistical analyses using various tools like Excel (advanced functions and formulas, advanced visualizations and dashboards), SQL(extracting data from related databases), R(end-to-end data analysis), and Tableau(dashboards and visual storytelling). I handle the end-to-end analytics lifecycle from data collection, data preparation, data cleaning, data analysis, data visualization, and generating insights and recommendations out of the dataset. List of reports I can perform (regularly): 1. LTV Analysis (using Shopify and Amazon) - What is the Lifetime Value of your customers? (This can also be segmented) 2. Churn Analysis - What is the drop-off rate / cancellation rate of your subscriptions? How long does a customer typically subscribe before cancelling? 3. Email Attribution Analysis - which of the emails you captured ended up converting and how long? 4. Product Repeat Purchase Analysis - Which among your products tend to yield repeat purchases from your customers? 5. Customer Repeat Purchase Analysis - On a segmented basis (month, year, etc.), what is the repeat purchase rate of your customers? How many of your first-time customers tend to buy again? 6. Average Time Between Repeat Purchases Analysis - What is the average time between first and second purchase of your customers? second and third? etc. 7. Facebook/Google Ads Analysis - Which among your ads perform the best? Which should you drop off? What kind of creative / messaging resonates with your audience? 8. Discount Code Analysis - Among the discount codes you've ran, which among them were most profitable? Which among them were most effective in converting your audience? 9. Market Basket Analysis - Which among your products are best bundled together to increase AOV and probability of purchase? 10. Product-Based LTV - Which among your products tend to yield high LTV customers? This list is by no means exhaustive, and I work on many other reports depending on the requirements of the analytics problems. I mostly work on customized reports that require critical thinking and creative problem-solving (for example, building a report to help identify the existing customer reactivation of a specific client on a month-by-month basis.) Professional Skills: Excel, R, Tableau, SQL, Databox, Research Writing, Thesis Writing, Statistical Analysis, Psychological Testing and Assessment, PowerPoint Presentation, End-to-End Data Analysis Process, Lead Generation, Influencer Outreach, Customer Support.

I am a seasoned data science professional with over 10 years of experience. At my full-time job as a senior data scientist for a large cruise company, my passion is leveraging both fundamental and advanced analytics to provide bespoke business and revenue solutions across the organization. Previously, I worked as a senior data analyst for a multi-billion dollar quasi-governmental company working to help fund affordable high-speed internet across the United States. My experience in data science and analytics is full-stack. What that means is you can rely on me from A-Z: processing your raw, messy data (ETL), finding significant insights in your data (EDA) and then uncovering subtle patterns via advanced statistics and algorithms (machine learning), and finally putting everything together with powerful visualizations in a compelling report. In addition, I am more than happy to help with any programming/scripting, database, and reporting automation projects. I am very comfortable programming in Python, R, and SQL. I also am an expert in visualizing and manipulating data with Tableau (including Tableau Prep). I earned my master's degree and Ph.D. in materials science and engineering from the University of Virginia where I specialized in computer modeling and simulation of nanoscale materials. Before that, I graduated from the University of Richmond with a double major in Physics and Chemistry.
