Distribution Channels:
Smart Micro Solar
IoT-based Photovoltaic Control
Smart Micro Solar (SMS) is based on an ESP32 microcontroller and enables monitoring and control of photovoltaic systems.
I support the further development of the firmware.
The SMS makes it possible to monitor and control the energy flow in the system to maximize self-consumption and minimize grid feed-in. The application offers the following functions:
- Monitoring of energy flow in the system
- Control of energy flow to maximize self-consumption
- Display of real-time data
Digital Product Files (Components-Cloud) according to VDI 2770
Prototype of a cloud-based solution for product information
In this project, I developed a prototype of a digital product file based on the VDI 2770 standard. The application enables importing and managing customer and order information as well as product documents. It offers the following functions:
- Import of customer, order and product data
- Automatic creation of user accounts for customers
- Display of information about orders and products
- Export of product data according to VDI 2770 standard
AdHoc Naturstein - Specialized CMS
Lightweight Content Management System for Rock Types and Damage Information
For the adhoc-naturstein.de project, I developed a specialized CMS that focuses on capturing and managing information about rock types and their damage. The application was implemented with Angular, PHP and MySQL and is resource-efficient, so it can be easily installed in a small hosting package. The main functions of the system are:
- User management and creation
- Capture and categorization of entries
- Clear presentation of information about rock types and damage
- Management of entries yet to be written
QR Code and NFC Projects
Innovative Solutions for Contactless Technologies
I have worked on a series of projects that use QR code and NFC technologies to create interactive and user-friendly applications. These projects included:
- Development of QR code scanner apps for mobile devices
- Implementation of NFC-based access systems
Note: Due to confidentiality agreements, further details about these projects cannot be shared publicly.
Additional Ionic Apps
Several additional Ionic apps have been developed by me that are not publicly accessible. These include an app focusing on background geolocation queries for iOS and Android and another app with document scanning functionality.
