Rohan Paul@rohanpaul_aiAI 评分4040A 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.
