ProPad Coiler
Turning Test Data Into a Deployment-Ready Machine
The ProPad Coiler is a paper-based protective packaging machine developed by Sealed Air. As an Applications Engineer on the second-generation iteration of the system, I worked across the full product development cycle - from hands-on hardware testing and failure analysis to software QA and data infrastructure - bridging the gap between the engineering R&D team and project stakeholders.
Note: Project details have been generalized to remove sensitive information.
Project Objective
My goal was to validate and refine the ProPad Coiler's second-generation design ahead of scaled deployment. This required identifying mechanical failure modes under real operating conditions, improving the operator-facing HMI experience, and building internal tooling to standardize machine configuration across varying paper types and coil specifications.
Testing & Cross-Functional Collaboration
I conducted structured in-house testing on the upgraded system, systematically documenting hardware failure points and working alongside the R&D team to design and evaluate prototype mechanical fixes. In parallel, I performed QA on the machine's HMI software, logging bugs and flagging interaction patterns that created friction for operators—translating field observations into actionable product feedback. I compiled testing findings and presented them to project managers and executives to inform development priorities.
Internal Tooling & Data Visualization
Beyond the physical product, I built an internal database to capture and standardize default machine configuration properties derived from testing data. I paired this with an interactive Excel and Power BI dashboard that visualized operating ranges across key variables—paper type, coil density, and coil dimensions—giving teams a reliable reference for commissioning decisions. I also oversaw the commissioning of machines shipping out of the facility, ensuring each unit met validated operating standards before deployment.
End Result
My testing program produced a structured record of second-generation hardware behavior that directly informed design improvements carried forward by the R&D team. The internal dashboard became a living reference tool for machine setup, reducing configuration ambiguity during commissioning. I successfully communicated findings to executive stakeholders, contributing to informed go/no-go decisions on the product's rollout.
