Ranked in the top 3% on Upwork globally, I’ve built trusted relationships with 80+ clients and received 60+ ⭐⭐⭐⭐⭐ reviews -- all within my first year of active use. With 14+ years of experience in Data Analytics, I operate at the intersection of strategy, analytics, and automation -- uncovering the signal behind the noise and translating it into insights leaders can act on. My work doesn’t just explain what happened; it clarifies why it matters and what to do next. As a Top Rated Plus freelancer, clients rely on me as a true thought partner, not just a technician. From Excel automation and SQL optimization to executive-level dashboards, financial models, and automated reporting systems, I design solutions that are precise, scalable, and decision-ready. Clients hire me when they need data analytics that answer questions like: • Where is our profit actually coming from? • What will revenue look like over the next 3–5 years? • Which marketing channels or business units are driving ROI? • How do we automate reporting so leadership sees the numbers instantly? My models and dashboards are designed for CFOs, founders, and executives who need confidence in their numbers. Core Expertise: ✔️Data Analytics & Engineering: Advanced SQL, Excel, SAS, and Access solutions that transform raw, fragmented data into reliable, analysis-ready assets. ✔️Statistical & Predictive Modeling: Regression, forecasting, and scenario modeling designed to support real business decisions—not academic exercises. ✔️Executive Visualization & BI: Tableau and Power BI dashboards that tell a clear story, highlight trade-offs, and drive alignment at the leadership level. ✔️AI-Driven Analytics & Automation: I embed AI directly into SQL workflows, Excel models, and financial analytics to accelerate insight delivery without sacrificing business context. My approach blends deep analytical reasoning (≈70%) with AI-powered automation (≈30%), ensuring speed and accuracy. ✔️Database & Performance Optimization: Purpose-built data structures and optimized queries that turn databases into high-performance decision engines. 💬 Client Feedback (⭐⭐⭐⭐⭐): (Recent Review from E.H.) "Subomi is the literal best, total icon!! I am genuinely grateful. I love partnering with a smart, hard, competent worker and he is just that! He is a great thought partner, beyond just someone to create models for you. I hired him for multiple projects and hired him additionally after I needed to redo work from someone who wasn't as thorough. He is extremely accurate, thorough, patient, helpful, willing to iterate, and does more than just create the models/chart/KPIs that you need - he helps you tell the story (both written and walking you through it) so you can understand all his assumptions. He makes projects better than what you would do on your own. Also, the work was so good that my bigwig private equity friend who reviewed his work was super impressed." 🌟 Let’s Build Something That Moves the Needle: If you need clarity from complexity, confidence in your numbers, or analytics that actually influence decisions, let’s talk. I don’t just deliver outputs; I deliver understanding, alignment, and results.
