Software engineer + GC · Systems lane
CA Lic. GC (B)Design exp.Founding Eng. · TexturaAcq. Oracle

Engineering rigor applied to construction operations. Founding engineer at Textura, the construction-finance platform later acquired by Oracle that processes billion-dollar-monthly volume for general contractors and developers nationally. A licensed General Contractor in California (Class B) with hands-on design experience, Shuo bridges the systems side with the build side — drafting scope, reviewing details, and walking the job on the same projects he runs the books for. At R&Y, Shuo owns scheduling, draw management, and financial transparency: every client sees the same dashboards we do — milestones, line items, pending change orders, and where the money is, in real time. Software is the back office. The building is the product.

Field and execution authority.

Hands-on master builder. Forms, framing, MEP, finish — Gonzalo's run every trade. When a crew hits a problem on site, he's the one who already has the answer. CA-licensed General Contractor. Three decades in the field, no shortcuts.

Role
Design–build A + GC

A 1962 single-story ranch on a deep lot in Walnut. We reorganized the main residence around a recovered north–south axis, then sited a detached one-bedroom ADU at the rear, preserving three mature California pepper trees and the original concrete drive.

Engineered shearwalls and a continuous load path resolved the structural changes without exposed steel. The two volumes are linked by a decomposed-granite courtyard that doubles as fire-department access.
