I build SQL and BigQuery data pipelines, reporting models, and custom dashboards that help teams track performance without manually combining data from multiple systems. My work covers the data behind the dashboard and the reporting experience itself: extracting data, cleaning and transforming it, defining business metrics, and building a clear interface for the people who use it. I’m Top Rated Plus on Upwork, with $70K+ earned and 100% Job Success. My projects include marketing and eCommerce analytics, BigQuery integrations, SQL development, automated reporting, and financial dashboards. WHAT I CAN HELP WITH • Data integration: Connect APIs, databases, spreadsheets, and business platforms to BigQuery. • SQL and data modeling: Turn raw data into structured reporting tables with consistent definitions, reusable transformations, and validation checks. • Automated pipelines: Build extraction and transformation workflows that keep reporting data up to date. • Custom dashboards and analytics applications: Build tailored reporting interfaces when your team needs more flexibility than a standard BI dashboard provides. • Looker Studio and Metabase: Build or improve dashboards when an established BI tool is the right fit. • Business analytics: Define and analyze revenue, profitability, acquisition costs, ROAS, customer lifetime value, and retention. I work with data from GA4, Google Ads, Meta Ads, Shopify, CRM systems, accounting platforms, and other business sources. For custom applications, I use AI-assisted development tools, including Claude and Lovable, alongside SQL, BigQuery, and Python. I validate the underlying data and calculations so the reporting reflects the business correctly. Past projects include daily MySQL-to-BigQuery data flows, multi-source marketing dashboards, eCommerce KPI reporting, and finance dashboards using QuickBooks and Xero. Whether you need the data foundation, the reporting interface, or both, send me your current setup and what you need to measure. I’ll help scope a practical solution.
