About Paulo

Do you need a secure, scalable web platform tailored to your processes? I help you turn complex ideas into simple, efficient, and robust digital solutions.

I am Paulo Serrano, a full-stack developer and CTO with over 20 years of experience in web and mobile development. I work with companies, institutions, and entrepreneurs to create systems that truly work and generate results: from institutional portals and intranets to apps for events, marketplaces, or medical management systems.

What sets me apart is the ability to lead complete projects—from architecture and backend to deployment and technical support—with an absolute focus on performance, security, and usability.

I master technologies such as:

Laravel (Livewire, Filament, Scout, React, Websockets)

CI/CD with GitLab, Github, Gitea

Docker and Docker Swarm

Meilisearch and semantic search

Integration with Keycloak, LDAP, and complex APIs

Artificial intelligences

I have developed solutions for:

Public institutions such as the National Republican Guard (Portugal)

International medical congresses (Oncology, Psychiatry, Cardiology)

Marketplaces, CRMs, and custom SaaS platforms

My added value? I listen to your needs, propose the best technological solution, and execute it transparently, quickly, and scalably.

I am available for:

Custom web development

Legacy system migration

Technical architecture and DevOps

API integration, security, and automation

Let's talk. I analyze your project without obligation and propose a clear and realistic solution. Your system will not only work: it will be a strategic asset for your business.
