About Jorge

Full-Stack Developer with over 7 years of experience designing and building critical enterprise applications. I currently lead a team of 9 developers, combining microservices architecture on Google Cloud, backend with Spring Boot, frontend with Angular, and ETL processes in Python on BigQuery and PostgreSQL.

What I do best:

- Backend in Java / Spring Boot: REST APIs, microservices, integrations, and performance optimization.
- Cloud architecture on Google Cloud Platform: Cloud Run, BigQuery, Workflows, Docker, and CI/CD.
- Frontend in Angular.
- Data and ETL: pipelines in Python, BigQuery, and PostgreSQL.
- Technical leadership: Scrum, estimations, code review, mentoring, and direct client communication.

I am a self-taught individual: I built my entire career without a degree, scaling from intern to Tech Lead in under five years thanks to a passion for technology and continuous learning. This is evident in how I work: pragmatism, focus on delivery, and a real ability to solve problems.

I balance freelance work with my main role, so I offer partial availability (afternoons, evenings, and weekends) with committed milestones and deliveries. This is well-suited for evolution projects, technical support, occasional consulting, or development without continuous presence during office hours.
