Project History
Langflow AI Software
https://langflow.orgLangflow is a powerful tool for building and deploying AI agents and MCP servers. It comes with batteries included and supports all major LLMs, vector databases, and a growing library of AI tools. Run a single or a fleet of agents with access to all your components as tools.
Algorithms for Matching Bullets
https://github.com/erichare/bulletrMy Ph.D. research was on algorithms for bullet matching. This involved creating an R package called Bulletr, which implements a set of statistical routines to automatically assess the probability that two bullets were fired from the same gun. We also deployed this as a web application, and the Annals of Applied Statistics accepted our paper on this research.
Omni Analytics Group Shiny Laboratory
https://labs.omnianalytics.orgAs part of my work for Omni Analytics Group, I created a web portal with a suite of Shiny applications developed by myself and my team. These applications prototype and highlight some of our capabilities as data scientists and give a preview of how analysis could look if deployed as a web application.
Past Consulting Work
https://omnianalytics.org/case-studies/A compilation of past consulting work I have taken part in at Omni Analytics Group can be seen at omnianalytics.org/case-studies. These range from simple exploratory data analysis projects to complex modeling and integration projects.
The intRo Statistical Software
https://github.com/gammarama/intRoA Shiny-based web application to complement an introductory statistics class. This application implements common statistical routines in an easy-to-use web application so that students are happy with their first exposure to statistics. The application is deployed and available at intro-stats.com.
