About Mario

Does your company need a custom technological solution or to scale a project that has become too small? As a Computer Engineer, my goal is not simply to "write code," but to design robust, scalable software that solves real business problems.

How can I help you and what value do I bring?
As I am in the final stage of my Computer Engineering degree, I have a very solid technical foundation in software architecture, algorithms, and best practices. This allows me not to be tied to a single language or framework; I learn and adapt quickly to the technology stack your project needs to offer the most efficient solution.

What sets me apart
I come from developing and supporting B2B (business-to-business) software. I have managed the complete cycle: from Full-Stack development of new features to resolving critical incidents hand-in-hand with the end client. I understand business pressure, I know how to communicate with non-technical profiles, and I translate your needs into clean, secure, and functional code.

Projects and deliverables I manage:

Custom Development: Creation of web applications and platforms from scratch (Backend and Frontend).

Integrations and APIs: Connecting your system with third-party services.

Databases: Design, modeling, and optimization of complex queries.

Maintenance and Refactoring: Bug detection, legacy code auditing, and performance improvements.

B2B Support: Evolution of SaaS products and resolution of technical blockers.

If you are looking for a problem-solving, versatile profile with strong analytical skills, write to me. I will be happy to analyze your case and propose the best technical path.
