01 / ABOUT

Engineering with purpose.

As CTO at a digital fitness and training platform, I lead the architecture and development of scalable systems that serve thousands of users daily.

My focus is on building sustainable products with clean architecture — leveraging Flutter for cross-platform apps, Laravel for robust backend systems, and Svelte for modern web experiences.

Beyond product development, I contribute to open-source projects, build automation tools, and consult with startups on technical strategy and scalable business models.

Pragmatic solutions. Sustainable architecture. Real impact.
