About

I'm an Electrical Engineer with 6+ years of experience, including 4+ years specialized in NFPA 72-compliant fire alarm and life-safety system design. I work remotely with engineering firms, contractors, and system integrators, delivering accurate, code-compliant fire alarm drawings ready for AHJ submittal.

Fire Alarm Design Services
I prepare complete design packages including fire alarm floor plans and device layouts, riser diagrams, sequence of operations (SOO), panel wiring diagrams, SLC/NAC circuit design, voltage-drop calculations, and battery sizing. I also handle drawing revisions from redlines, plan check comments, or field changes.

Cross-Discipline Coordination
I coordinate fire alarm designs with architectural, mechanical, plumbing, and fire-protection drawings to keep device placement, conduit routing, and system interfaces conflict-free before drawings go out for review.

Brands & Systems
System Sensor, Silent Knight, Kidde, Potter, Edwards, Siemens, Notifier, BOSCH, Gamewell, Napco, Simplex.

Electrical Protection Background
Before fire alarm design, I worked as a Senior Relay Engineer with Siemens SIPROTEC protection relays — installation, testing, commissioning, retrofitting, and troubleshooting in substations and power plants.

Core Skills
