Tiago Serra

As a Software Engineer at Sportradar, I architect and deploy cloud-native solutions for high-traffic sports data and ad-tech platforms. My contributions span backend microservices (Go, Typescript/Node.js, Python), frontend applications (React, Vue), and robust CI/CD pipelines (GitLab, ArgoCD, Terraform) on AWS and GCP infrastructure. Key Highlights: - Backend and Cloud Expertise: Developed and maintained Typescript, Go and Python services, integrating with AWS (Lambda, SQS, EC2) and GCP (cron job, Kubernetes)for resilient and scalable architectures. - Front-End & Microservices: Built and refactored React and Vue apps, employing microfrontend strategies for modular, efficient deployments. - DevOps & Cloud: Implemented Infrastructure as Code (IaC) with Terraform, streamlined container orchestration with Docker and Kubernetes, and optimized AWS usage for cost-effectiveness. - Performance & Quality: Drove measurable performance gains (e.g., 15.6% JS execution time reduction), upheld strict testing standards, and adopted lean, iterative development approaches. - Stakeholder Collaboration: Worked closely with product owners and stakeholders to clarify requirements, fostering alignment and delivering impactful product increments. - Mentorship & Documentation: Guided junior developers, maintained onboarding resources, and championed knowledge-sharing sessions to cultivate a collaborative engineering culture. Recognized by peers for my adaptability, proactive communication, and leadership, I thrive at the intersection of backend development, cloud services, and front-end engineering, delivering secure, scalable solutions in fast-paced, Agile environments.
