Back to original languageAbout Franco
I help companies and startups build fast, stable, and scalable digital products for thousands of users, without technical headaches.
With over 3 years of experience in Full Stack development, I specialize in designing robust backends with NestJS and creating modern, high-performance interfaces with Next.js. My focus is on efficiency: I optimize databases, design clean APIs, and solve complex integrations (from legacy systems to real-time flows).
What do I bring to your project?
Maintainable code: I apply Clean Architecture and Domain-Driven Design (DDD) so that the software can continue to grow without becoming obsolete.
Experience with real systems: I know what it means to have a system in production; I handle deployments, CI/CD, and problem-solving under pressure.
Autonomy: I lead complete modules from planning to deployment. I work by deliverables, ensuring you see real value in every advancement.
