• Passion for productivity tooling, automation, and emerging tech trends

Preferred

• Familiarity with Power Platform (Power Apps, Power Automate, Dataverse) and/or the Microsoft 365 ecosystem as an added advantage
• Experience with DevOps practices and tooling: GitHub Actions or Azure DevOps CI/CD pipelines, container orchestration with Kubernetes, and Docker‑based deployments (optional but a strong plus)
• Experience building AI‑powered applications: integrating LLMs (OpenAI/Azure OpenAI), vector databases, embeddings, and RAG patterns
• Knowledge of identity and access management (OIDC/OAuth 2.0, SSO, zero‑trust patterns)
