What I'm looking for

I'm looking to build scalable, secure SaaS and enterprise products using Java, Angular, cloud platforms, modern APIs, and AI integrations. I value clean architecture, collaborative delivery, and opportunities to improve performance and maintainability.

I've built enterprise applications for over 14 years, most recently delivering SaaS features in the Omeda ecosystem at OneSeven Tech with Angular 18, Java REST APIs, JWT authentication, and AI integrations.

At The CE Shop, I engineered a high-traffic e-commerce platform used by thousands of daily users and designed REST APIs for its Learning Management System. I also improved delivery through code reviews, CI/CD pipelines, and collaboration with AWS and PostgreSQL infrastructure teams.

At Indra Sistemas, I optimized large-scale energy distribution processing by 90% through algorithmic and database tuning. I also led the migration of the Mi EDEEste mobile app from React Native to Flutter and built reusable React components for Naturgy.

Earlier, I delivered mobile payments, telecom recovery, inventory, and database optimization solutions across Java, .NET, Angular, Oracle PL/SQL, and SQL Server. I enjoy building secure, maintainable systems with clean code, SOLID principles, and modern cloud tooling.
