I Build Data-Driven Decision Systems | Power BI, SQL & Python

Most businesses don’t lack data — they lack clarity. I build executive dashboards that turn data into real decisions. I help founders, CEOs, and teams turn scattered data into clear, decision-ready dashboards using Power BI and modern BI tools. Through my work, I’ve developed a structured approach called ConecDatos, focused on building executive control systems, not just dashboards. What I do: Design executive dashboards for leadership teams Build KPI systems aligned with revenue and growth Connect marketing, sales, and operations data Transform messy data into a single source of truth ConecDatos Framework (how I work): Define decisions → What do you actually need to decide? Identify KPIs → Metrics that truly impact the business Structure the data → Clean, connect, and organize sources Build the dashboard → Clear, actionable, decision-ready What I typically build: CEO / Executive dashboards Marketing performance dashboards (Ads, funnels, ROAS) Sales & pipeline dashboards Operations & performance tracking systems Most dashboards look good but don’t help you act. I focus on building dashboards that actually get used. If your data is messy, unclear, or not helping you make decisions — I can fix that. Recent work includes: Funnel performance dashboard (live project) KPI systems for marketing and sales tracking Data structuring for decision-making dashboards
