I am a full-stack software engineer with experience building and refining web applications, microservices, and AI-driven features. I combine backend architecture and frontend development to deliver reliable, maintainable products.

At Compile Strength I led a refactor of core application features using Next.js and introduced automated testing with Vitest, increasing test coverage by 40%. At Bobadilla Tech I built an AI-driven doctor recommendation engine and integrated a mental-health chatbot, working across Express.js, React.js, PostgreSQL, AWS and GCP.

I design and implement microservices and worker-based async processing, and I have delivered projects that include APK security analysis, a note-taking app, a URL shortener, and an advanced Android camera app using Vulkan shaders. I emphasize performance, maintainability, and testability in my work.

I hold a BSc in Computer Science from the National University of Engineering and I’m motivated to join teams that value scalable architectures, rigorous testing, and meaningful AI integrations.
