If your team is still chasing numbers every week, rebuilding the same reports, reconciling different figures from different teams, or running dashboards nobody fully trusts — the problem isn't effort. It's the system underneath. I build reporting infrastructure that runs itself. Using SQL, Power BI, Excel, and AI-assisted analysis, I help finance, operations, and e-commerce teams replace slow, error-prone manual work with clean, automated systems designed for real decisions — not just presentations. I've delivered this for retail businesses, FMCG companies, agencies, and e-commerce teams, with a 5.0⭐ rating across every completed engagement. 🔹Most teams I work with come to me with one of these: • "Our reports take too long to update every month" • "Different teams report different numbers for the same metric" • "Dashboards look fine but don't explain why things changed" • "Leadership questions the data before they act on it" • "We're still doing everything manually in Excel" If any of those sound familiar, you're exactly who I work with. ✅Track record 5.0 ⭐ rating across all completed jobs Jobs completed: dashboards, SQL, AI/ML, Excel, Google Sheets Portfolio: Power BI, SQL, Geo analysis, AI automation 🔹 What I deliver ✅KPI & executive reporting AI-assisted • WoW, MoM, QoQ, YoY comparisons, trend diagnostics, and rolling averages — with AI-powered anomaly detection that flags what changed and why, before your next meeting. ✅Power BI & dashboard systems • Interactive Power BI dashboards with automated refresh and drill-through filters. • Excel and Google Sheets dashboards built for non-technical users who need to act fast. ✅SQL reporting & data modeling • SQL querying, joins, transformations, and reporting-ready data models. • ETL workflows and structured master tables that reduce manual errors and support live dashboards. ✅AI/ML analysis & automation • AI/ML analysis on e-commerce and behavioral datasets. Automated workflows using Python and AI • APIs — including predictive models, churn analysis, and segmentation systems. ✅ Excel & Google Sheets systems • Advanced formulas, Power Query, XLOOKUP, dynamic arrays. • Financial models, P&L dashboards, trackers — no fragile VBA, built to last without babysitting. ✅ Geo & sales analytics • Geographic performance analysis and sales territory dashboards in Excel and Power BI. • Behavioral segmentation and scenario evaluation for sales and operations teams. ✅Reporting automation & cleanup • Consolidation of scattered sources into one reliable system. • Data validation, audit views, and semi-automated pipelines — built to run without babysitting. 🧠 Why Clients Work With Me • Strong business logic, not just technical output — clients badge me "Committed to Quality" and "Reliable" • AI tools applied to speed up delivery without cutting analytical corners • Clean, scalable designs that don't break after one update or one new data source • Dashboards built to explain change, not just display totals • Clear communication and structured delivery from kickoff to handover • Experience across retail, FMCG, e-commerce, banking, and telecoms 📌 Typical Projects • Executive KPI dashboards • Power BI with live SQL connections • P&L and financial reporting • Retail and e-commerce analytics • Behavioral segmentation • Customer churn prediction • Geo and territory analysis • HR analytics (headcount, attrition, compa-ratio) • Excel and Google Sheets overhauls • AI/ML analysis on business datasets ❌ Not a good fit if: • You want visuals without solid data structure underneath. • You expect insights without clean inputs. • You're looking for a one-off patch rather than a reliable system. • I work best with teams who value clarity, consistency, and confidence in their numbers — and want reporting that saves time every single week, not just once. Happy to review your current reporting setup and map out a clear path forward. Let's talk.
