I have seven years experience solving complex data problems by quickly mastering the right tools for each project. My business philosophy is to provide solutions that generate value for the client long after I deliver them. I'm constantly undergoing rigorous study to better understand and integrate evolving technologies to offer more comprehensive support to my clients. I can help implement: - various types of automation, including quality assurance automation - certain cloud solutions with GCP, AWS, and Microsoft AzureML - data transformations - machine learning models - dashboards - command-line interfaces - financial analyses - spreadsheet solutions (Google Sheets and Excel) - various types of interactive visualizations - software modules (in particular, I'm currently learning to build Python modules in Rust for faster performance) I have formal training as an engineer up to the Master's level. I also have training from past full-time roles as research engineer and data analyst. I attribute much of my current skills to ongoing self-study using online resources such as Packt and O'Reilly technology and business training. As a research engineer, I developed experimental machine learning models with Python and wrote corresponding technical reports. These efforts were also the subject of my graduate work. As a data analyst, I collected and analyzed data from solar energy infrastructure projects and conducted external market research to determine future project viability in different regions. Since joining Upwork, I have assisted clients with various ML and data engineering tasks. As mentioned earlier, I am currently training to be a full-stack solutions architect with both coding and strategic planning offerings.

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.

Looking for an experienced software engineer who has extensive industry experience, wide ranging technical skills, great communication skills, can work independently, and has an ability to really 'get' the big vision of what you want to achieve? Need someone who can fine-tune your new AI app or figure out why it's not working? UNDERSTANDING I don't just blindly focus on the technical aspects of the project. I will make sure that I understand exactly what your business wants and how the project will be used in the real world, so I can deliver something that is intuitive for users and exceeds your expectations. CREATIVITY I love coming up with brilliant and creative ideas for how your product could be improved or tweaked. If you're looking for a passive, mindless worker then you should hire someone else. I will frequently inject fresh new ideas into the discussion, and challenge your thinking. QUALITY What I can offer that you probably won't find from other freelancers here is a very high level of production build quality and testing. Instead of delivering the minimum to you, I excel in delivering a high-quality product that is not an unstable or incomplete prototype, but a production-ready product that is complete, user-friendly, intuitive, and free of bugs. EXPERIENCE I have 15+ years of experience as a software developer, building both front-end and back-end software applications, specialising in Java, JavaScript, React, Python, Django, C#, and SQL. I can integrate with LLMs such as ChatGPT to build AI features. I'm confident solving complex problems, designing new architectures, building DevOps pipelines, integrating 3rd party APIs, designing relational databases. I have exceptional skills in the area of problem-solving and trouble-shooting. COMMUNICATION What also sets me apart from most developers are my fantastic communication and people skills, making me a breeze to work with, and allowing you to understand the big picture even if you’re not a technical person. INDEPENDENCE I have and an ability to work independently to make technical decisions and solve problems, meaning you don't have to waste time micro-managing me. But it's up to you how much you delegate. I will find out from you which decisions you want to be a part of, and which ones you are happy to entrust to me. You always have the final say. WHAT TO EXPECT If I start a project with you, here is what to expect: 1. I will have a lengthy conversation with you to make sure I fully understand all of your expectations and requirements. Based on this, we will agree on individual delivery milestones. 3. I will write up the technical design for each milestone, along with an estimate of development time, and a plan for how to quality test it once it's complete. 4. I will work on each milestone and deliver a preview of it to you for feedback and minor tweaks. 5. I will then begin a round of quality testing to find bugs and ensure the product is stable and complete. 6. We will discuss and feedback and also bugs found during testing, and negotiate what can be realistically changed or fixed within the timeframe and budget of the project. 7. I will apply any fixes or minor tweaks that we agreed upon. 8. I will then deliver the final version of the software to you, complete with documentation for how to set up the development environment, how to deploy the software, and how to use it. Don’t wait, get in touch now and we can plan our first project together!
