Proof of Usefulness Score
You're In Business

The submission describes a legitimate freelance embedded software consulting business with verifiable testimonials and a clear professional focus. However, the PoU score is significantly limited by the nature of the project (a service business rather than a scalable tech product) and poor quality input data. The submission includes highly unrealistic claims (e.g., audience is 'everyone', 'most people have used my product') and misuse of financial terms ('marketcap' for revenue). While the service provides high utility to specific clients (Kelio, TPL), it lacks the broad reach, innovation, and scalability required for a high score in this framework.

Description
A Software Engineer specialized in Embedded Systems & IoT, I work as an independent consultant since 2021. Today, I help my clients designing and developing their embedded software. I make a point in writing well-architectured code that can be maintained and reused on the long term. My languages of predilection are C and Java, which allows me to write both low-level embedded firmware and higher-level human-interfaced software. I focus on writing high-quality code (i.e. no warnings, no untracked TODOs) in a proper development environment (i.e. build automation, proper git workflow, etc.) rather than functional but hastily tested and non-documented code. A French native currently based in the Nantes area, I am fluent in English and have an intermediate level of Spanish, which allows me to work in an international context.
