DevFlow
DevFlow streamlines the code review process for distributed engineering teams. It integrates with GitHub and GitLab, offering a real-time collaborative editor, AI-powered review suggestions powered by LLMs, and a metrics dashboard tracking review velocity and bottlenecks.
// key outcome
Reduced average code review time by 40% for teams of 10+ engineers.
The Problem & User Context
Engineering teams at fast-growing startups struggled with slow, asynchronous code reviews that blocked deployments and frustrated developers. Review cycles averaged 48 hours, creating compounding delays.
Approach & Tradeoffs
We built a real-time review layer on top of existing Git workflows. Reviewers see live cursors, can co-annotate diffs, and get AI suggestions that flag common patterns. Integrations with Slack and Jira notify the right people instantly.
Technical Architecture
Next.js frontend with Tiptap-based diff editor. Node.js backend with Socket.io for presence. PostgreSQL for review data, Redis for ephemeral presence state. OpenAI GPT-4 via function calling for suggestion generation. Deployed on Kubernetes with AWS EKS.
