About José

Experienced developer, I am now orienting myself towards software architecture, at the crossroads of technical, systems, and business challenges. I will assist you in the entire development of your software, in regulated or non-regulated environments, or as part of studies or audits on specific topics (performance, feasibility, industrialization, security, compliance, etc.).

I design reliable, maintainable, and easily evolvable systems, by relying on clear interfaces, a thorough understanding of functions, and attention to the overall structure from the early stages. I place particular importance on internal and external interfaces, which influence user experience, integration with other systems, compliance with standards, and the ability to efficiently test and evolve the code.

Specializing in embedded software, I also have solid skills in cryptography and cybersecurity. I particularly address operational technology (OT) cybersecurity issues, relating to the IEC 62443 standard.

I enjoy tackling complex technical problems, diving into details, and taking on challenges that require balancing a big-picture vision with implementation rigor.
I prefer assignments with clear objectives, defined collaboratively, to move forward in a healthy and structured framework.
