• Integrate APIs with frontend teams.
• Follow Git-based CI/CD workflows (GitHub/GitLab, Jenkins, Docker).
• Build LLM-orchestrated apps using LangGraph and LangChain.
• Integrate OpenAI, Anthropic, HuggingFace, or custom LLMs into production.
• Build and tune RAG pipelines on Pinecone or PGVector.
• Write efficient queries against 3+ years in Python (Django), including 6+ months hands-on production GenAI.
• Strong REST API development (Django/Flask/FastAPI).
• Hands-on LLM integration (GPT-4, Claude, Llama) with LangGraph/LangChain.
• RAG pipeline experience (Pinecone, PGVector).
• PostgreSQL/MySQL with efficient query writing.
• Solid grasp of design principles, modularity, and Git.
• Full-time B.E./B.Tech, 60%+ across 10th/12th/degree (relaxable for strong technical candidates mention in resume).
• Background in IT services/IT consulting.
• Fluent in English and Hindi.
• Stable career history no frequent job-hopping.

Good to Have

• AWS/GCP/Azure exposure.
• CI/CD and Git-based deployment familiarity.
