Senior Backend / Full Stack Developer
About Me
I am a Senior Backend / Full Stack Developer with over 10 years of experience building production-grade enterprise applications across financial, insurance, and healthcare sectors. I specialize in scalable distributed systems, microservices, event-driven architectures, API design, messaging, and cloud-native delivery. My hands-on expertise includes Node.js and TypeScript for backend development, alongside strong skills in Java/Spring Boot and Golang ecosystems.
Throughout my career, I have led architecture discussions, mentored engineers, and implemented CI/CD pipelines to ensure reliable and efficient software delivery. I am passionate about applying Clean Architecture principles, Test-Driven Development (TDD), and conducting thorough code reviews to maintain high code quality and operational excellence.
I have extensive experience working remotely and collaborating with cross-functional teams to translate business requirements into robust technical solutions. My communication skills are fluent in Spanish and professional English (C1-level), enabling me to work effectively in diverse environments.
I am proficient in a wide range of technologies including Java (versions 8 to 22), Golang, JavaScript, TypeScript, Python, and SQL. I am also skilled in frameworks such as Spring Boot, Node.js, Angular, and tools like Docker, Kubernetes, Jenkins, Kafka, and ActiveMQ. My experience spans cloud platforms including AWS, Azure, and GCP, and I am well-versed in DevOps practices and methodologies like Scrum, Kanban, and Clean Architecture.
I continuously seek to expand my knowledge through certifications and training in areas such as software architecture, DevOps, machine learning, and advanced programming techniques. I am available immediately for remote work and eager to contribute to innovative projects that challenge my skills and foster professional growth.
