Product Engineering, Custom Software Development & Consulting
I help companies and founders design and build robust software systems – from concept to production.
As an independent software engineer with a Master's degree in Computer Science – specializing in high-integrity systems – I focus on building reliable, maintainable, and scalable solutions for Apple platforms, Linux environments, and connected IoT systems.
My work combines clean architecture, strong engineering principles, and product thinking.
