Hey there

🚀 About Me :

  • 🌱 Proactive results-oriented Analyst with a unique 5-year background in process optimization and a proven track record in retail analytics. Proactive with a focus on development and implementing the best solutions.

My journey started in a highly regulated field, where I learned to optimize complex systems: reduced costs by 73%, accelerated document flow by 2.4x, and boosted reporting speed by 40-80%.

I then deliberately mastered the modern data stack (Python, SQL, Power BI) and successfully applied it in retail:

  • ✅ Built a forecast model with ~95% accuracy (MAPE)
  • ✅ Automated key reporting processes
  • ✅ Slashed claim processing time from 2 months to 1 day

I have a deep passion for data analytics, seeing it as a form of art that allows us to unravel the complexities of reality and make informed, impactful decisions.
