SPRING '23 PROJECTS
Fall 2023 projects will be announced soon. In the meantime, take a look at last semester's projects!
Client Projects
Our client teams work with industry partners to build products ranging from full stack web development to machine learning.
Recidiviz is a data platform that develops tools for people in all areas of the criminal justice system (corrections officers, policymakers, judges, and more). Our project focused on building a web tool for policymakers and prosecutors to easily calculate time served in prison (based on original sentence, offense, etc.) and visualize sentencing outcomes.
Etsy is an e-commerce platform that allows users to sell and purchase a wide variety of handcrafted and vintage items. For our project, our team accomplished a proof-of-concept of certain portions of Etsy's Image Upload pipeline in order to better understand how a future, re-architected efficient/optimized pipeline might be built on Etsy's new service platform.
Sprinter Health addresses the technological gaps and barriers for access to diagnostics at scale. Our team migrated Sprinter Health's Sprinter app, which was used by their clinicians to get instructions and information from android to iOS. In the end, our changes were directly tested with real clinicians.
Mentored Project
Our mentored team focuses on learning the essentials of software development and simultaneously develops an full-stack web application for a non-profit organization.
