Welcome to my personal portfolio! I’m glad you’re here. Here you’ll find some of my recent projects and a few of my professional accomplishments. Feel free to click around.
About Me
I began studying Package Engineering over 6 years ago at Michigan State University where I learned quickly that packaging involved a little more than corrugated board and tape. What originally drew me to packaging was the vital role it played in society. I was intrigued by its immense attention to detail and how decisions made by packaging engineers were almost always unidentified by the end consumer. After accepting a position as the first Packaging Engineer at Envases Ohio, I quickly grew and found myself expanding into other departments. In the spring of 2020, I was promoted to Engineering Project Manager at E.O.
When I’m not working, I’m still working – or at least messing around with something. It is rare to find me not preoccupied with something that has piqued my interest. I’m currently the founder and developer of Pixsle – a mobile application that allows photographers to deliver photos directly to their clients using facial recognition algorithms. Pixsle has been in development for over 4 years and finally hit the Android and iOS app stores in early August 2019. Along with Pixsle, I also enjoy flying helicopters. I’m currently pursuing my private pilot’s license for the Robinson R44 Helicopter. To unwind, I enjoy playing guitar. I currently play a nylon classical acoustic guitar, studying finger-style melodies. Last but not least, I enjoy working out at the gym. Every day I find a way to move!
I am currently employed at Envases Ohio LLC, a sister company of Envases Universales, as the Engineering Project Manager. Before full-time at Envases, I worked for Michigan State University as an Undergraduate Researcher for Plastic Food Packaging. I also have previous experience as a Packaging Engineer Co-op working for Sherwin-Williams where I was mentored alongside three great packaging engineers.
I welcome any connection whether it be a colleague, manager, or passionate person, so please feel free to contact me.
Work Experience
Currently I:
• Coordinate the implementation of new manufacturing lines dedicated to the production of 211, 214, 307, and 404 size cans.
• Reduce SKU's and increase the performance of UN rated packages.
• Qualify new suppliers, increasing profitability, throughput, and contingency plan alternatives.
Currently I:
• Develop and oversee all packaging designs/redesigns including technical drawings, packaging specifications and artwork/labeling.
• Ensure regulatory compliance according to CFR 49 and United Nations (UN) certification process.
• Involved in implementing crater prevention systems guaranteeing a silicone free product and facility.
• Intimately involved in quality processes including the development of quality management systems (QMS), root cause analysis, and the creation of corrective action reports.
• Wrote work instructions and standard operation procedures (SOP’s) for eventual ISO 9001:2015 certification.
• Developed in-depth packaging specifications ensuring document control, spec sustainability, and the overall accuracy of all products produced.
Professional Photography for the average event goer.
Pixsle is a mobile application for Android and iOS devices that allows photographers to deliver photos in real-time directly to their clients’ mobile devices using facial recognition.
Pixsle App has two versions: Photographer and Client. Similar to popular models such as Uber, where two separate applications work in tandem (i.e. a driver and passenger), Pixsle features a Photographer and Client application that combine to form one cohesive entity. Photographs are captured by the photographer on a DSLR camera, the photo is then forwarded to the Photographer Pixsle app and, through facial recognition, delivered to the end Client app. Simply put, a photo is captured on a professional camera and sent directly to the client in less than 10 seconds.
As a Undergrad Researcher I:
• Researched a new bio-based antimicrobial package material designed to extend the shelf life of perishable produce.
• Set up minimum inhibitory concentration studies to determine fugal resistance.
• Utilized a gas chromatography to analyze foam release kinetics. Analyzed foam physical characteristics using image processing software.
As a Packaging Engineer I:
• Wrote a new package quality report on the SAP database drastically improving retrieval time of package quality metrics.
• Coordinated with procurement and suppliers to input and maintain package specifications. Performed comparative study for multiple package designs.
• Developed package testing procedures ensuring proper compatibility between package and product.
• Tested a new iteration of pail package design and administered flow through current lines.
As a Warehouse Manager I:
• Coordinated hundreds of daily shipments.
• Organized 25,000 products on online database.
• Developed and maintained relationships with customers and suppliers.
• Requisitioned and organized store merchandise to optimize warehouse space.
