About Francisco Javier

I am a Digital Solutions Architect with over 6 years of experience designing, developing, and implementing complete end-to-end applications. I combine a full-stack profile (Java, Python, JavaScript, Angular, React) with a solid foundation in infrastructure and containers (Docker, deployments, automation, reproducible environments) and a clear focus on scalable architecture, performance, and software quality.

I have worked on projects for sectors such as banking, insurance, and technology, building microservices, robust APIs, distributed systems, and high-performance web applications. I master both backend and frontend, which allows me to design coherent, efficient solutions aligned with business needs.

I can help you to:

Design and develop complete applications from scratch
Create modern microservices-based architectures
Build fast and maintainable web interfaces
Optimize performance, security, and scalability
Implement Docker environments and deployment workflows
Integrate SQL and NoSQL databases (MongoDB)
Accompany you throughout the entire project lifecycle (SDLC)
My goal is to deliver solid, scalable, and well-thought-out digital solutions, bringing technical vision, execution capability, and clear communication throughout the project.
