Hi, Iām Javier! š Iām a data science leader who works at the intersection of analytics, modeling, experimentation, and production-grade AI. My North Star is simple: Solve real problems with data and share the playbook.
Data Science & Applied AI
I first honed my analytics and modeling skills by building valuation and forecasting solutions using techniques such as ARIMA and gradient-boosted trees, then deepened my craft in health tech by developing applied machine learning and AI products for consumption at scale.
Today, I lead data analytics at Jeppesen ForeFlight, unifying how the organization measures and understands business, product, and financial performance. I partner closely with leadership to turn data into trusted insight, while laying the groundwork for advanced analytics and applied AI as the business evolves.
Languages
My daily languages include R, Python, SQL, and Bash, but my preferred language is R. I use R for a wide range of work including ML/AI model development, package creation, communication with data warehouses and REST APIs, vector DB + RAG solutions, automation pipelines, interactive apps, and websites (for example, this site was built with R + Quarto).
Data Science Communities
There are a plethora of online and in-person data science communities to learn from and share your own experiences. Online communities for open-source languages and data science are incredibly welcoming and below are my favorites:
