Luis Alberto Graciano Padierna
Full Stack Web Developer
Medellín, Colombia
Professional Summary
Senior Full Stack Developer with 8+ years building and stabilizing mission-critical production systems with Java, Spring Boot, Angular, and TypeScript on AWS. Specialized in designing complex architectures, leading development teams, and delivering web and mobile products end to end under Agile/Scrum. I pair technical leadership —code review, design and coding standards, mentoring, and releases across QA, Pilot, and Production— with hands-on development of advanced modules, REST APIs, and microservices.
I complement my corporate experience with freelance web and mobile projects delivered from end to end: analysis, architecture, development, deployment, and observability. I work across a broad stack (Go, Node.js, Flutter, PostgreSQL, Oracle, MongoDB, Kubernetes, CI/CD) on a solid foundation of AWS services (EC2, S3, RDS, EKS, Lambda), focused on shipping reliable, maintainable software aligned with business goals.
