Développeur back-end
Au cours de sa carrière, Aron a fourni de nombreuses solutions à long terme. Un produit logiciel qu'il a développé en 2006 reste utilisé quotidiennement, un témoignage de sa robustesse et de sa valeur durable. À Ericsson, il a contribué à la composante principale du réseau 5G, le Service d'application de la téléphonie, mettant en lumière son expérience en matière d'infrastructure critique.
Aron a également travaillé avec Proxify, obtenant des retours exceptionnels pour son expertise technique, sa fiabilité et son approche collaborative.
Given my previous experience with voice bots, I was invited to this project as an expert consultant. I gave insight on prompting, voice2voice networks, transcription handling, and real-time information injection. The project uses ElevenLabs (which sadly isn't in the technologies list). My role here is not a constant load, more like being involved occasionally when there are uncertainties around technology or user experience. My role was more crucial in the beginning of the project when obviously there were more decisions to make. As I'm writing this, the project is about to go live, so my work here is mostly done.

Adnexo is operating a system that tracks trucks, and generates road usage reports to the Swiss government. Due to legislatory changes, their usage more than quadrupled in a short period, and their system was unable to handle the load. My first task was to stabilize the system, and make it performant again, by optimizing both source code and infrastructure. But the load was still growing, so the CTO decided to move over to AWS, which meant moving 7 billion records within a very small timeframe, since the system is real-time, so it can't be down for long. I also did a major refactor of the core of the system, making it parallel and scalable, and many new features and upgrades.

I worked for OpenAI as an AI trainer, my role was mostly focused on the Chat Completion feature, introduced in ChatGPT 4. I trained ChatGPT for using various programming languages, mostly Python, to detect when the use of programming is required to answer the question, and how to verify if the solution given by the program is correct. I was part of a group of about 4000 people.
