Over the past year, there has been a lot of churn & activity in the FINOS GitProxy project - a git-aware reverse proxy for enforcing security controls & custom push protection for source code repositories. In that time, we've hit architectural speed bumps, dealt with security vulnerabilities in naive or unspecified assumptions, and have strived to deliver more features on a regular release cadence. That doesn't come without its challenges.
Git Proxy is a flagship FINOS project and an enabler for many FINOS members. Importantly, securing outbound source code - and doing so without sacrificing the benefits of open source participation - solves a real and complex problem for our industry. As a result, the project has to evolve & adapt quickly.
In this talk, I'll walk through a roughly year-long journey from struggling in the muck in early prototyping, API dead ends, and difficulty in "connecting the dots" between many complex domains into a totally new way of working that has allowed me to rapidly iterate and push the project forward.
Using new agentic-based development techniques and tools such as GitHub Copilot & Claude Code, I've been able to deliver a feature-complete, top-to-bottom rewrite and fresh, new architecture of the core system while still continuing to leverage "classic" software engineering - expressive & well-thought-out abstractions, battle-tested frameworks & libraries, and a corpus of human ingenuity & wisdom. These tools, only when combined with this bedrock of expertise, allowed me to move well past prototyping into a production-ready revamp - and proved that the most powerful thing you can give an AI is a well-designed API to call.
