Manage artifacts, enforce branch strategies, and utilize Maven and Nexus for release-to-live (RTL) development, including versioning, dependencies, and packaging standards.

Participate in code reviews and maintain documentation for backend services. Key skills and experience

Hands-on experience with Python frameworks such as Flask, FastAPI, or Django.

Proven experience building and maintaining RESTful APIs.

Solid understanding of API design, security, versioning, and scalability.

Python proficiency, LLM orchestration (RAG), and hands-on experience designing end-to-end intelligent applications using Microsoft's cloud ecosystem

Familiarity with serverless architectures and event-driven design.

Knowledge of model orchestration, prompt engineering and LLM evaluation workflows.

CI/CD and Git-based workflow knowledge.

Ability to ensure data consistency, logging, and error handling across distributed services.
