• Highly practical approach focused on delivering value. Enjoys writing frontend, backend, and infrastructure code, resolving real blockages, and avoiding complex abstractions or unnecessary over-engineering.
• Excellent Communication & Evangelization Skills:
• Ability to communicate architectural decisions, deliver internal workshops, and write flawless integration guides.
• Autonomy & Proactivity:
• Ability to detect performance bottlenecks in tooling or developer workflows, proposing and implementing quick wins without requiring micromanagement., * Backend Ecosystem: Advanced domain in developing robust and scalable services using .NET Core / C# and Node.js (NestJS / Express).
• API Design & Resilience: Design and consumption of REST APIs, applying resilience patterns (circuit breakers, retries, rate limiting).
• Modern Frontend & Micro-Frontends (MFE) Architecture:
• Core Frameworks: Expert domain in React / TypeScript or Next.js for developing complex, modular, high-performance interfaces.
• Module Federation: Hands-on experience with Webpack / Vite Module Federation for runtime dynamic loading of MFEs, managing shared scopes, and error isolation (Error Boundaries).
• Authentication & State: Management of OIDC / OAuth2 identity and authentication flows, along with global/context state management.
• Containers & Orchestration

• Docker: Demonstrable experience in managing, optimizing images (multi-stage builds), and securing Docker containers.
• Kubernetes (K8s): Experience in orchestrating, deploying, and administering applications in K8s clusters (deployments, services, ingresses, configmaps).
• CI/CD, GitOps & Quality:
• CI Pipelines: Creation and management of Continuous Integration pipelines for build automation, executing unit/integration tests, static code analysis, and pushing images to registries (Harbor).
• GitOps & CD: Practical experience in GitOps workflows and Continuous Deployment, with a preference for ArgoCD.
• Testing: Experience in automated testing and a shift-left quality culture.
• Nice-to-Have:
• AI-Assisted Development & Agents: Experience or strong interest in AI-powered development workflows (Gemini, Copilot, Cursor, etc.), as well as integrating or developing AI agents and conversational interfaces to automate development or platform tasks.
• Cloud Computing (Multicloud & GCP): Experience in Multicloud environments. Practical knowledge and experience in Google Cloud Platform (GCP) (Cloud Run, GKE, IAM, Secret Manager) or involvement in cross-cloud migration projects from Azure to GCP.
• Infrastructure as Code (IaC): Terraform: Knowledge or experience in provisioning and automating cloud resources using Terraform, facilitating the creation of scalable, replicable environments integrated into platform deployment workflows.
• Observability: Knowledge of telemetry and traceability standards such as OpenTelemetry, as well as experience implementing and querying observability dashboards in the Grafana Stack (Prometheus/Mimir, Loki, Tempo, K6).
• Feature Flags: Management of progressive deployment workflows using Feature Flags (Unleash).
• Tooling & Internal Developer Portals: Familiarity with the Backstage ecosystem (creation of Software Templates/Boilerplates and TechDocs).
