I am a data wizard with a knack for turning raw data into actionable insights. With a solid background in data science and engineering, I've mastered the art of building and maintaining data ecosystems. My skills shine in creating and deploying complex data architectures and models that boost business strategies and processes. I'm a humble data scientist always working to improve my engineering skills, especially when it comes to handling infrastructure on GCP and AWS. I've got a knack for developing software, particularly using Shiny.
I’ve built robust web scraping systems to collect real estate and e-commerce data, keeping businesses ahead of the curve. My predictive models and market analyses have made a significant impact, ensuring precise pricing and smart strategic decisions. I’ve also been the go-to for supporting marketing with A/B tests, fine-tuning product recommendations, and boosting operational efficiency.
