Description

My overall responsibility was to create the software for a new version of their existing product from scratch. The product is a computer with the aforementioned software installed on it, and is mounted on top of the panel in front of the driver seat. This product is not only used by the driver to plan what routes to drive for the day, it's also used to communicate with the signs and speakers inside the bus.

If we dissect the overall responsibility, we find out that the development process consists of software architecture and design, implementation, bug fixing, debugging, testing and documentation. Not necessarily in that order. The software is built with a modular architecture, includes APIs, a GUI, I/O (for server communication via radio and GPRS, COM-ports for signs and speakers, as well as local files) among other things.

In addition to the product itself, I built an internal web browser-based build system for easy management. This build system allowed us to compile and even "freeze" versions on a customer-basis.

Description

My responsibility was to create web browser-based tools for the IT support team from scratch.

One of the tools I created is used for task scheduling and status management. The tool allowed them to schedule a task to occur once, or at arbitrary intervals, starting from a specific date and, optionally, end at a specific date. For any specific day they would be able to see what tasks to perform that day and, optionally, update the status of a given task.

Another tool I created is used to manage configuration files for the computers in the network. The configuration files are processed by a tool called CFEngine.
