Two engineers rebuilt a FedEx supplier platform in 3.5 months with repository graphs

- Two forward-deployed engineers rebuilt a live FedEx supplier’s delivery orchestration platform in 3.5 months, versus an original estimate of 7–8 months.
- Their main advantage was not faster code generation, but a repository-wide knowledge graph that mapped modules, dependencies, data flows, and domain language.
- The team documented the entire codebase in markdown first; agents read that map before writing code, so generated changes matched the real architecture and fit inside context windows.
- Humans still reviewed all 122 merged pull requests, while the models wrote about 90% of the code.
- The post argues that with the right infrastructure, two engineers can now produce output that used to require a much larger team.
