Personal Government ID - Text Extraction App

A computer vision-based app to detect and extract text from the personal image of Guatemala's government ID.

I developed the app for a banking company from Guatemala City, Using python for the back end and Shiny apps for the front end.

Generating Chatbot Insights from Product Features

The client relied on Chatfuel, a chatbot web platform, to share content and stories on social media. The product team communicated its need to drive actionable insights that result in growth.

I collaborated with the client to achieve this goal by setting up the instrumentation guidelines that would follow an automated process in tracking new products without affecting current integrations. By enabling product managers and stakeholders to create actionable reports based on these new criteria, this project allowed end-to-end tracking to understand product and customer insights.

S-Curve and Trace Logic

I developed a project management model that maps the relationship between tasks on a schedule to understand the impact of a change in scheduling, the criticality of a task, how risky that change is (with Monte Carlo simulations), and how that impacts the overall project.
