What Used to Take Months Now Takes Days (obie.medium.com)

In an impressive demonstration of AI-assisted development, a new organizational knowledge distillation service called Nexus was built in just four days during the author's downtime amidst regular job responsibilities. The founder and CTO of ZAR, with 30 years of coding experience, highlighted the immense efficiency improvements enabled by Claude Code, an AI coding assistant. Nexus captures and organizes technical conversations—structured around decisions, lessons learned, and discussions—from various platforms like Slack and GitHub, creating a semantic graph that can be queried by AI agents. The significance of this project lies in its potential to revolutionize knowledge management in software development. By distilling raw conversation transcripts into manageable, queryable knowledge, Nexus addresses a critical gap where traditional development practices often lose valuable insights. The technical architecture leverages modern technologies such as Ruby 4.0, Rails 8, PostgreSQL with pgvector for semantic search, and Rust-based Oxigraph for efficient storage and querying of information. This rapid development highlights a shift in the competitive landscape; as AI tools enable faster and cheaper software creation, the rationale for open-sourcing custom solutions—once a hallmark of software development—may now jeopardize competitive advantages.
