AI Engineer & Platform Owner · Drake Hub
Drake Construction (via Emapta Global)
Sole engineer of an internal AI-first construction management platform, from architecture to production support.
- Designed and shipped a 38-table, 5-role platform: scheduling (Gantt with dependencies), daily logs, financials (schedule of values, change orders, AIA G702/G703 billing), estimating, subcontractor bidding, plan management, timesheets and a client portal.
- AI in production, not demos: field crews send a photo and a Spanish voice note and get back a structured English daily log; an assistant reads plans, logs and site photos and edits the Gantt; Q&A over construction drawings and per-project semantic search.
- An estimating pipeline (plan PDF → scope extraction → in-house pricebook → branded quote PDF) that replaced a paid third-party tool, calibrated against real submitted bids.
