Data Analytics · Business Intelligence · Cloud Analytics

I turn complex data into decisions people can use.

My analytical practice combines more than a decade of multilingual search quality, language evaluation and AI data work with SQL, BigQuery, Looker, Power BI and formal study in data science and business analytics.

Analytical Practice

A clear path from questionto recommendation.

The method stays visible so the result can be reviewed, challenged and reused.

  1. 01 Frame

    Start with the decision, not the dashboard.

    I define the question, the audience and the action the analysis must support before choosing metrics or methods.

    Business question · Scope · Success criteria
  2. 02 Prepare

    Make the evidence trustworthy.

    I inspect structure, standardise fields, identify duplicates, document assumptions and preserve enough context to explain every transformation.

    Cleaning · Validation · Joins · QA
  3. 03 Analyse

    Test what the headline number hides.

    I compare segments, markets, intent and performance so the largest figure is not automatically mistaken for the strongest opportunity.

    SQL · Spreadsheets · Python · Exploration
  4. 04 Explain

    Turn findings into a usable answer.

    I connect the result to commercial context, communicate limitations and build a recommendation that can guide the next step.

Selected Analysis

Technical execution connectedto a real decision.

The projects combine analytical engineering, data quality and business interpretation across financial risk monitoring and international market opportunity.

BigQuery + Looker Enterprise

Portfolio risk analytics

Loan Portfolio Risk and Concentration Monitor

I built an end-to-end cloud analytics workflow that validates 270,299 loan records, creates reusable BigQuery risk marts and turns exposure, status and geographic concentration into an interactive Looker monitoring dashboard.

  • Data modelling
  • Quality checks
  • Dashboard design

Market opportunity analytics

SEO Market Opportunity Analysis

I cleaned and compared 2.15 million monthly searches across Spain, France and the United Kingdom. The analysis separated raw demand from accessible non-brand opportunity and found that France offered the strongest launch position, with a 69.7% non-brand share.

Relevant Experience

Years of evidence, evaluationand structured judgement.

My experience with data began before the modern BI toolkit. It was built through search evaluation, multilingual quality work, structured review, publishing QA and risk-sensitive investigation, and is now extended through SQL, cloud analytics and dashboard development.
