Jake K.

I’m an R Shiny developer and data engineer who builds clean, fast, and reliable data tools using R Shiny, Python, and SQL. Most of my work is taking messy or slow processes and turning them into smooth, production-ready apps or pipelines. I build Shiny apps with editable tables, dynamic filters, custom JS, and clear visualizations, and I use DuckDB or cloud storage to make big datasets load instantly. On the Python side, I migrate old SAS/SQL code, build Databricks pipelines, and optimize workflows so teams can get results in minutes instead of days. I’ve done this across healthcare, biotech, and public health, and I’m good at taking unclear requirements and turning them into something simple and usable. If you need someone who can build or fix a Shiny app, or speed up a Python workflow, I can handle it.
