Limestone Digital团队用2名工程师在3.5个月内重建了FedEx供应商的交付编排平台,而原估计需7-8个月。他们首周未写代码,而是构建了覆盖模块、依赖、数据流和领域术语的全仓库知识图谱(markdown文件),AI智能体据此生成代码,最终约90%的代码由模型编写,122个合并PR均经人工审查。AI计算成本约每名开发者每月200美元,该团队被客户CTO评为公司内“表现最佳的团队”。

Two forward deployed engineers rebuilt a live FedEx supplier's delivery platform in 3.5 months. The original estimate was eight.

Their advantage did not begin with faster code generation, but with a repository-wide knowledge graph covering modules, dependencies, data flows, and domain language.

2 years ago you'd need 5 engineers and double the timeline for this output.

They mapped the entire repository into markdown files covering modules, dependencies, and data flows.

Agents read that map first, so generated code matched the real architecture.

That structure kept every task inside a context window the model could hold.

Humans reviewed all 122 merged pull requests, and the models wrote about 90% of the code.

You set up that infrastructure and two engineers produce what used to take a full team.

Kudos to @mardehaym’s Limestone Digital team.

A delivery orchestration platform that supplies FedEx, estimated 7 to 8 months to rebuild their core system. We delivered in 3.5 months with 2 engineers and 122 merged pull requests in the first 90 days. I want to walk through how, because "we used AI and it was faster" doesn't help anyone. Their codebase had real users, real logistics operations, and real consequences if something broke. This is brownfield, not a weekend prototype demo. Week one, we didn't write code. We scanned the entire repo and built a knowledge graph: markdown files documenting every module, dependency, data flow, and domain term. Our agents read that graph before touching anything. Teams skip this constantly. They point an agent at a repo, hand it a ticket, and get code that compiles but misunderstands the architecture. I've seen it across 100+ engagements. When someone says "AI doesn't work on our codebase," they almost always skipped context acquisition. Every ticket ran a six-step loop: define, spec, plan, implement, test, document. The agent handles about 90% of code generation. A senior engineer reviews every PR, and nothing merges unless they can verify it, explain it, and debug it without the agent. We call that the V.U.E. gate. The 50% time reduction came from three things: upfront context eliminated false starts, the agent handled mechanical coding so engineers focused on design and review, and tight spec-to-PR discipline kept scope from drifting. AI compute: about $200 per developer per month. Their CTO called our pod the "top performing team" inside the company. Both engineers got discretionary bonuses, twice. That's what our Velocity Framework was built for.
