José Higinio Sosa profile

Profile

Practical engineering for products that need to run well.

Full stack software developer with more than six years of experience across the complete web development lifecycle. I have worked on enterprise, financial and e-commerce platforms with Vue.js, Angular, React, TypeScript and Node.js, relational databases and cloud and container deployments.

My cloud practice includes Microsoft Azure, App Services, Docker, Kubernetes and OpenShift, with Jenkins CI/CD pipelines and Linux support scripts. I integrate REST APIs, JWT authentication and modular solutions focused on performance and security.

I currently work as a freelancer on independent projects with Vue.js 3, Composition API, Pinia and TypeScript. I collaborate with clients and development, business, QA and infrastructure teams, from requirements gathering through testing, technical documentation and incremental delivery.
