⚡ Power BI & Excel Dashboard Expert | Turning Messy Data Into Decisions You Can Trust Most businesses don't have a data problem — they have a visibility problem.

I run Marino Data Management & Consulting (MDMC), a data integration + analytics practice that builds and maintains reliable reporting systems for growing businesses. I take ownership end-to-end: integrating sources, engineering clean models, automating refreshes, and delivering dashboards leadership can trust—then managing the system so it keeps working as data changes and teams grow. You can hire me for one targeted project or full end-to-end ownership—I’ll scope it clearly, validate the numbers, and ship something that stays reliable. Typical work includes: -Data cleanup & normalization (standardizing exports, deduping, aligning schemas, analysis-ready tables) -Integration & pipelines (APIs/exports, repeatable ingestion + refresh workflows) -Data engineering & modeling (transformations, KPI definitions, documentation/governance) -Automation & reliability (scheduled refresh, reconciliation/QA checks, anomaly flags, debugging mismatches) -Visualization (Power BI / Looker Studio dashboards for exec/marketing/sales/ops) -Ongoing management & consulting (updates, new KPIs, permissions/access patterns, performance tuning) I use Python/R when you need automation, API pulls, repeatable transformations, or lightweight data services beyond what a BI tool can handle. Core tools: Power BI, Looker Studio, SQL/BigQuery, Power Query, Excel/Google Sheets, GA4, and common CRM/ads platform exports.
