Hire the Best Test Results & Analysis Professionals

After two decades in corporate research, analysis, analytics, and presentations, I shifted to freelance work so I could bring my skills in Excel, data science, and presentation development to smaller businesses, nonprofits, and individuals doing work that matters. I’ve worked across business, education, and community organizing, and I know how to deliver results whether I’m optimizing a marketing model, building an executive dashboard, or cleaning up a spreadsheet nightmare. There are plenty of talented freelancers out there. What sets me apart is the combination of technical skill, high standards from working with demanding clients, and a deep commitment to making sure your data actually helps you move forward. I take pride in the clarity, speed, and reliability of my work because I know how costly it can be when something isn’t done right the first time.Some people speak code, some people speak data, some people speak business, and some people speak human. I speak all of their languages and am an expert translator between them all. When You Work With Me: I sign on as part of your team—fully invested in (y)our success. I take time to understand your business and goals, and tailor my approach accordingly. I focus on one project at a time, so you’ll have my full attention. I communicate clearly and consistently, with regular updates and opportunities for feedback. I often go beyond the original brief because I see something interesting in the data that could be useful to you—and if it is, I’ll share it. If you’re not sure whether your project is a fit, feel free to reach out. I’m always happy to talk through it. Services 📊 PowerPoint & Presentation Design The perfect presentation balances style and substance. I’ll help you build a slide deck that not only looks great but also tells your story clearly. If you’re presenting live, I can also create separate versions optimized for delivery vs. standalone reading—and coach you on how to present it like a pro. 📈 Excel & Spreadsheet Automation From spreadsheet creation and optimization to BI tools and beyond, I build Excel tools that are powerful, intuitive, and cleanly designed. I also bring macro/VBA, dynamic formulas, and dashboarding into play as needed—without making the file a black box. 📉 Data Visualization The best analysis is useless if no one understands it. I design clear, impactful visualizations that highlight what matters—no spaghetti graphs, no rainbow pie charts, just good design tailored to your audience. 🧠 Data Science & Analysis I specialize in making complex data feel approachable. Whether you're looking for basic insights or advanced modeling (regression, clustering, ensemble methods, machine learning), I can help you uncover patterns, tell a story, and make better decisions. 📝 Copy Editing Whether it’s an essay, a white paper, a grant proposal, or a research deck, I’ll help tighten your writing and make sure it’s polished, persuasive, and typo-free.

I'm a quantitative financial analyst and algorithmic trading data scientist with over 15 years of professional experience in technical and trading roles at hedge funds and major trading companies. I'm an expert at all aspects of systematic trading, going from raw idea, to fully automated systematic trading strategy. Strategy design & signal development Whether you arrive with a rough sketch or a fully-formed hypothesis, I help translate it into clear rule sets or statistical signals. Robust back-testing I build event-driven test environments that respect market microstructure: realistic fills, spreads, latency, and transaction costs. Applied machine learning (when it adds value) Some problems benefit from additional pattern-detection—regime classification, order-flow imbalance, or adaptive position sizing. Where appropriate, I incorporate ML techniques, but only when they improve risk-return relative to simpler rules. Deployment & oversight Strategies can be delivered as semi-automated tools (you review signals, click to trade) or fully automated pipelines posting orders to Interactive Brokers, Alpaca, or exchange APIs. Independent model review Funds often retain me for a “second opinion” on in-house or vendor models before capital is committed. I examine code, data-handling, leakage risk, and performance attribution, then provide a concise report highlighting strengths, weaknesses, and remedial steps. Expert witness & litigation support I assist in cases involving algorithmic trading, model risk, or market abuse—providing clear technical analysis and expert testimony. --- I'm very laid back about how engagements begin, and I appreciate that clients are keen to have conversations with multiple freelancers before choosing one. I'm happy to have a call and chat through your ideas and what I can add while you're deciding. Whilst I'm not new to quant finance, I am new to Upwork, and I've set my rate artificially low while I get some initial reviews. Pls see my work history, bio, and website for more information.

Most AI products do not fail because the idea is bad. They fail because the build gets stuck between prototype and launch. I help founders, startups, agencies, and business owners turn ideas, unfinished products, and manual processes into working AI MVPs, SaaS applications, and automation systems that are ready for real users. Recent projects delivered on Upwork include: ✅ Built an AI-powered lead capture system that automated inquiry collection, generated personalized responses using OpenAI, and reduced manual lead handling. ✅ Developed an AI MVP for startup validation, allowing the founder to test the concept with real users before committing to full scale development. ✅ Created and tested an n8n automation workflow that connected Google Form submissions to Gmail notifications, ensuring reliable and automated communication. Some of the business challenges I hae helped solve include: 📌Turning manual lead management processes into automated workflows that save time and improve response speed. 📌 Helping founders move from idea stage to a functional MVP they can demonstrate, validate, and improve using real user feedback. 📌Connecting forms, APIs, databases, email systems, and business tools into a single automated workflow. 📌 Reducing repetitive operational tasks through n8n automations and AI-powered business processes. 📌 Building practical SaaS applications and internal tools that support business growth without unnecessary complexity. My core tools include n8n, OpenAI, Claude, Supabase, Firebase, React, React Native, APIs, Webhooks, Base44, Lovable, Replit, Make, and Zapier. I work best with founders and teams who already have an idea, workflow, or prototype and need a practical builder who can turn it into a working product quickly and efficiently. If your project is stuck between idea, prototype, and launch, send me a message. I will review your current setup, identify the gaps, and recommend the fastest path to getting it into users' hands.
