Engineering & Software
CAD, additive manufacturing, electrical, software and HVAC engineering, from the team behind OnSite and RevvLog.
Get StartedOur Services
Full-spectrum engineering capabilities to bring your vision to life.
CAD Design
From concept sketches to production-ready drawings, our mechanical design team delivers precise 2D and 3D CAD models using industry-standard tools. We handle tolerance analysis, GD&T, and full assembly documentation so your designs are manufacture-ready from day one.
Additive Manufacturing
Rapid prototyping and low-volume production through FDM, SLA, and SLS printing technologies. We optimize parts for printability, structural integrity, and material selection, delivering functional prototypes in days rather than weeks.
Software Engineering
Custom software solutions built for performance and scale. We architect web applications, embedded systems firmware, data pipelines, and IoT platforms using modern frameworks and battle-tested practices.
Electrical Engineering
End-to-end electrical design including schematic capture, PCB layout, power distribution, and embedded controller integration. We take projects from breadboard proof-of-concept through production-validated designs.
HVAC & refrigeration
Residential and light commercial comfort cooling and heat pumps, including high-pressure equipment consistent with EPA Section 608 Type II certification. Motor vehicle air conditioning (MVAC) refrigerant service under EPA Section 609. When your project needs it, we can pair field work with software, diagnostics, and IoT.
Our Products
Software we build and run ourselves.
OnSite
Field inspection software for HERS raters, home inspectors, HVAC technicians, and contractors. Schedule visits, capture photos offline, and generate professional PDF reports.

Where engineering meets ingenuity.
SpinFlip LLC was founded on a simple premise: great engineering should be accessible, efficient, and uncompromising. Our founder's career spanning mechanical design, software architecture, and data analytics across aerospace, automotive, and technology sectors forged a conviction that the best solutions emerge when disciplines converge.
We operate at the intersection of hardware and software, bridging the gap between physical systems and digital intelligence. Whether you need a precision-machined prototype, a production-grade web platform, or a fully integrated IoT solution, SpinFlip delivers end-to-end engineering with a relentless focus on quality and performance.
Every engagement begins with understanding your objectives and ends with a solution that exceeds them. We are not a body shop; we are your engineering partner, invested in outcomes that matter.
