• Design, develop, test and support AI/ML, GenAI, RAG, conversational AI, copilot and AI‑agent solutions aligned with business and architecture requirements.
• Build document ingestion, parsing, chunking, embedding, indexing, retrieval, reranking, grounding and prompt‑orchestration pipelines.
• Develop tool‑enabled agents and multi‑agent workflows using function calling, memory, enterprise APIs and human‑in‑the‑loop patterns.
• Build scalable backend services and integrations using Python, FastAPI, REST APIs, microservices, asynchronous processing and event‑driven patterns.
• Develop or integrate modern user experiences for chatbots, copilots and agents using React, TypeScript or equivalent frameworks when required.
• Implement real‑time AI interactions using WebSockets, Server‑Sent Events or token streaming, including safe rendering and resilient error handling.
• Integrate AI solutions with enterprise applications, workflow platforms, databases, vector stores, search services and cloud data platforms.
• Implement evaluation and quality checks for retrieval, groundedness, accuracy, hallucination risk, prompt performance, tool execution, latency and cost.
• Apply Responsible AI, PII protection, access controls, data privacy, secure coding, prompt‑injection mitigation, content safety and auditability controls.
• Containerize and deploy services, contribute to CI/CD pipelines, automated tests, monitoring, logging, release management and production support.
• Troubleshoot issues across data pipelines, models, prompts, agent workflows, APIs, vector stores, streaming services and user interfaces.
• Prepare technical designs, implementation notes, test evidence, runbooks, solution walkthroughs and delivery updates.
