Worked on a personal research project with the intention to create my own start-up company. The project involved designing the hardware and also the software for a wearable device by cows which informs the farmer if the cows are healthy or suffering from disease. The sensor was also able to inform the farmer of the exact day that the cow was ready to be inseminated (heat detection).

Worked on a contract (6 months) role as consultant software engineer for Intrion. I helped the company to successfully finalize the software for one of their customer robotic installations in France. The role required from me to do a technical and functional analysis for specific parts of the software, write tests, debug these parts and document them. The installation involved an Automatic Storage and Retrieval System products like chocolates, cakes, etc. The products were being stored on the machine by a robotic crane. They had to stay inside the storage for various amounts of hours. Later on, they were being extracted and were getting delivered to the appropriate pallet (or hand picking) stations in order to be sent to a client.
