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.
