Portfolio
Pastorek Landscaping
In November 2024, I had the opportunity to rebuild a website previously developed with Joomla, transitioning it to the WordPress platform. The project involved a local landscaping company that required a new hosting provider and urgent assistance to restore their website online. Utilizing their old cPanel backup, I set up a local development environment using Microsoft Windows, MySQL, and PHP. Within a tight two-day timeframe, I successfully migrated their site from Joomla to WordPress, ensuring a smooth transition and meeting their immediate business needs.

Hapbee Manufacturing
Based on feedback from the C-Suite we had to improve our manufacturing process in the early stages of investor rounds and our Indigogo campaign. Due to tight security requirements at the start the manufacturing time for a single device took anywhere from 3 to 7 hours with Bluetooth and a custom Xamarin App. By using Microsoft Windows SDK, Microsoft .NET, and custom test and manufacturing hardware we improved our manufacturing time to a total of 12 minutes between programming and testing as of December 2022.
