Deep technical expertise. Multi-state relationships.

DeepBlue Engineering, LLC was founded by Maggie Ye, PE — a licensed engineer with 10+ years of experience and 400+ bridges designed, rated, and inspected across Louisiana, Mississippi, and Texas. The firm was built to solve a persistent problem in the DOT and structural consulting market: workload spikes, tight deadlines, and rework caused by inconsistent subconsultant quality.

DeepBlue fills that gap by delivering submission-ready work with minimal oversight, functioning as a seamless, high-reliability extension of client teams — whether that's a prime consultant managing a DOT contract, a municipality replacing a local structure, or a contractor needing construction-phase engineering support.

We operate as a lean, senior-led practice: every project is handled directly by an experienced, licensed engineer — not passed down to junior staff — so quality and reliability stay consistent from proposal to final stamped plans.

End-to-End Capability

From concept through submission-ready plans — design, drafting, load rating, and inspection across all bridge and structural types, without relying on outside support.
