  • Strong full-stack development with Angular/TypeScript, Java/Spring Boot, RESTful APIs, distributed systems, and secure application design.
  • Practical experience with LLM application patterns, model APIs, RAG, embeddings, vector search, prompt design, structured outputs, tool calling, evaluation, observability, and AI security.
  • Hands-on use of Claude, GitHub Copilot, or comparable AI coding assistants with disciplined review, testing, and security practices.
  • Strong CI/CD and DevOps experience covering automated builds, testing, deployment, release controls, and monitoring; familiarity with Docker, Kubernetes, and cloud-native platforms preferred.
  • Experience with Python, SQL/NoSQL databases, data integration, caching, and data-intensive applications.
