Isabella Antonella R.
Data Automation Specialist | SQL Tuning & Performance | Power BI
Your team is losing hours every week exporting data by hand. Your dashboards time out because nobody ever tuned the queries behind them. Reports arrive too late to act on, and half the numbers don't match between departments. That's the problem I get hired to solve. I'm a Business Economist and Data Analyst with 4+ years turning messy, manual, or slow data operations into automated systems that just work. 🔧 What I actually do: I automate what's eating your team's time. For a US-based education holding company running 8 separate entities, the VP of Finance was spending 2 full days a week manually exporting QuickBooks data and pasting it into shared sheets. I built a Python pipeline on GCP that runs the whole thing daily, automatically, with fault isolation per entity. Result: 16 hours a week back, zero manual touchpoints, 100% accuracy. I turn scattered data into a business health dashboard your leadership actually trusts. Right now I'm running this exact playbook for an import/export distribution company: connected their Odoo ERP straight to BigQuery, designed a proper data mart (Kimball star schema), and I'm building out the KPI dashboards leadership uses to see the business in real time. Along the way, I don't just build what's asked, I actively flag data quality issues nobody had caught (unconverted foreign currency getting mixed into totals, negative delivered quantities) before they turn into bad decisions. I fix slow queries, not just build reports on top of them. Dashboards are only as fast as the SQL behind them. I do hands-on query tuning: EXPLAIN ANALYZE, indexing strategy, cost-based optimization. In one project I took a query from ~600ms down to under 10ms. If your reports are slow, timing out, or your database groans under load, that's a fixable problem, not something to just live with. 💰 Also worth knowing: earlier in my career I translated financial data into upsell/cross-sell strategy that generated $1.5M+ in net profit, so I don't just automate processes, I know which numbers actually move the business. 🛠 Tech Stack & Tools: • BI & Visualization: Power BI (DAX), Looker Studio (formerly Data Studio), Tableau • Databases: PostgreSQL, MySQL, BigQuery, MongoDB, Databricks • Integrations & APIs: QuickBooks Online REST API, Odoo API, OAuth 2.0 • Automation & Programming: Python (Pandas, NumPy), GCP (Cloud Functions, Scheduler), Power Query, KNIME • Query Performance & Tuning: EXPLAIN ANALYZE, B-Tree Indexing, Execution Plan Analysis, Query Refactoring, Cost-Based Optimization I am actively seeking opportunities where I can apply my unique blend of analytical skills and commercial perspective to help forward-thinking international companies make smarter, data-driven decisions. If your data operation runs on manual work, slow queries, or reports nobody fully trusts, let's talk. 📩 Send me an invite or drop a message with what's slowing your team down
