- Drafted and coordinated buildable AutoCAD permit drawings across 24 MEP projects, translating engineer markups and field conditions into construction documents.
- Selected and sized mechanical equipment, then produced cut sheets and equipment schedules for construction document sets.
- Designed a full HVAC system with load calculations in Carrier HAP for a variety of different projects insuring optimal airflow, and audited drawings against code and permitting requirements.

Engineering, operations,
and leadership.
- Built the company website with a customer intake form that automatically feeds submissions into a structured Google Sheets record.
- Automated the booking workflow so online scheduling syncs to a calendar and triggers instant email notifications.
- Engineered a repeatable operating process covering pricing, intake, scheduling, and expense tracking.
- Manage a ~$650K annual operating budget across 24 officers and committee categories for an ~80-member chapter, using a multi-sheet Excel tracking and forecasting system I built.
- Reduced chapter debt by ~52% through improved tracking and an alumni-driven repayment strategy, and cut budget forecasting variance by ~75%. See the system →

Treasurer Operating System
A multi-sheet Excel system that rolls officer, committee, food, fine, and utility spending into one live budget dashboard with variance and projections.
Pool Table Room Conversion Plan
A to-scale room layout, itemized bill of materials, and use policy — a full execution plan built to win approval from our alumni board for a shared-space upgrade.
