Why senior-led teams ship faster, not slower

Most agencies staff a project with senior engineers for the sales call and discovery phase, then quietly swap in a junior bench once the contract is signed. The result is predictable: velocity drops right when the hard architectural decisions need to be made. At JDNextGen, the engineers who scope a project are the ones who build it. That's not a marketing line — it's a staffing constraint we hold ourselves to, because the alternative costs clients far more in rework than it saves in day rate.
