What I'm looking for

I seek roles building scalable, secure cloud-native systems with end-to-end ownership, strong testing and CI/CD, and opportunities to improve performance and reliability.

I am a Full Stack Developer specializing in backend development with Java, Spring Boot, Python, and Django, with extensive AWS and cloud-native experience. I have built and deployed production platforms with 700+ automated tests, up to 90%+ code coverage, and achieved a 95/100 Lighthouse performance score, emphasizing performance, scalability, and security.

I design end-to-end systems from backend to frontend, implement CI/CD and IaC (Terraform), and apply TDD and security practices (CodeQL, Bandit, OWASP). Trained as an AWS Cloud Practitioner and trilingual in English, Spanish, and Portuguese, I deliver reliable, production-grade systems and drive continuous improvement across the stack.
