IoT Solutions Architect and Embedded Hardware Engineer

About Me

I’ve built my career across diverse technological environments, contributing to projects that combine engineering, data, and systems architecture in different countries and sectors.

Each context has been an opportunity to understand how technology adapts to various operational, regulatory, and cultural realities.

This international experience allowed me to develop an integrated view of systems — understanding that beyond hardware or software, what truly matters is the communication between them and their alignment with business objectives.

Throughout my career, I’ve worked in environments where hardware, software, and data converge, ensuring communication, stability, and scalability across technical layers. That path shaped my ability to think systemically and focus on interoperability and efficiency.

Today, I direct my work toward solutions that turn information into decisions and technology into measurable results — ensuring that every implementation creates operational impact and sustainable value.

What I Bring:

  • System-level thinking: the ability to connect devices, data, and infrastructure into coherent, maintainable, and scalable ecosystems.
  • Cross-domain experience: exposure to scientific, corporate, and operational environments that demand reliability, precision, and adaptability.
  • Hands-on engineering mindset: from embedded design and data flow modeling to infrastructure management and process optimization.
  • Analytical and pragmatic approach: focusing on traceability, efficiency, and measurable operational outcomes.
  • Continuous evolution: expanding into data, backend, and AI-driven systems to deliver end-to-end technological value.

Current focus:

  • Designing RAG-based AI infrastructures for enterprise applications.
  • Developing scalable IoT and data pipelines for sensors monitoring.
  • Expanding skills in data science & backend development.
