SPRING 2025 PROJECTS

Client Projects

Our client teams work with industry partners to build products ranging from full stack web development to machine learning.

DatabasesData Lakehouses

Amazon partnered with Codebase to upgrade DeltaCAT 2.0 by strengthening A.C.I.D. transactions, improving persistence, and adding Rivulet-convertible dataset support. These enhancements make the open-source data lakehouse more powerful for AI/ML-ready, industry-scale workflows.

Machine LearningFrontend

Recidiviz partnered with Codebase to build an LLM-powered platform that uses automation to streamline parole and probation workflows and reduce bottlenecks, boosting efficiency for case managers and improving outcomes for formerly incarcerated individuals.

Machine Learning

Sony PlayStation partnered with Codebase to develop a BERT-based NLP model that analyzes chat threads in real time to flag high-risk behaviors. Built with Python and PyTorch, the scalable solution enables early intervention and reinforces PlayStation’s commitment to player safety.

Machine Learning

Sony PlayStation partnered with Codebase to create a PyTorch-based ML classifier that identifies video game screenshots versus real images. The solution reduces reliance on third-party moderation, lowers costs, and improves player safety with a scalable in-house approach.

Mentored Project

Our mentored team focuses on learning the essentials of software development and simultaneously develops a full-stack web application for a non-profit organization.

Full Stack Web

Lotus Bloom, a community organization serving 1,000+ families, partnered with Codebase to build a secure online forum for staying connected during school breaks. The custom platform supports resource sharing, strengthens family bonds, and advances Lotus Bloom’s mission of community empowerment.
