  Senior Backend Developer / DevOps Engineer

  3M | Heredia, CR

  • Built production REST APIs and microservices for product configuration and availability in Spring Boot (Java) and Node.js (JavaScript), plus Server-Side Rendering (SSR) applications — applying Clean Code, Clean Architecture, and design patterns with TDD-driven unit tests, documenting them with Swagger / OpenAPI, securing them with OAuth / JWT, and integrating SQL and NoSQL (Elasticsearch) with content-management systems.
  • Implemented CI/CD pipelines and release automation across multiple projects using Jenkins, GitHub Actions, Red Hat OpenShift Pipelines, and AWS as owner of a standing DevOps continuous-improvement workstream; led cloud migrations and Infrastructure as Code (AWS CDK) for containerized workloads (Docker / ECS / Kubernetes / OpenShift), including deployment rollback strategies.
  • Engineered search relevancy and tokenization improvements by analyzing domain data with Elasticsearch (NoSQL) to drive search value.
  • Reduced production issues by 75% by leading incident management and root cause analysis with post-mortems, remediating security vulnerabilities across backend services and cloud/container infrastructure, and migrating legacy code to modern services.
  • Standardized requirements capture and increased shared understanding across development and QA — reducing rework and clarification cycles by 40% — by authoring a User Stories / Use Cases documentation framework and driving knowledge-transfer handoffs to different team members.
