Design, optimize, and manage prompt engineering pipelines for diverse AI models. Implement secure, scalable, and observable AI-invoking microservices. Handle live prompt-response cycles with latency, load, and failure resilience in mind. Benchmark and stress-test AI-enhanced services in production-like conditions. Lead prompt engineering initiatives across team boundaries using CI/CD and service mesh patterns. 🧱 Course Structure The course is divided into 5 modules plus a Capstone Project. Each module includes: Code-first tutorials Hands-on labs Real-world integration case studies Assessments (peer-reviewed + automated) 📦 Module 1: Foundations of Prompt Engineering in Microservices Objective: Set the groundwork for integrating LLMs using prompt engineering techniques within a microservice architecture. Topics: LLM APIs: Capabilities and Constraints (OpenAI, Anthropic, etc.) Anatomy of a “Prompt Microservice” Service Contracts for Prompting APIs Statefulness, token limits, context windows Idempotency and Retry logic Tutorial: Build a minimal LLM API gateway using FastAPI or Express.js Design a "Prompt Broker" microservice that routes and transforms prompts Lab: Create an auto-documenting prompt schema registry Integrate OpenAI's ChatCompletion with contextual memory across microservices Case Study: Multi-tenant support in AI-enhanced ticket classification (e.g., Zendesk-style system) Assessment: Peer-reviewed: Prompt Broker contract design Benchmark: Prompt-response latency < 400ms under 100 RPS 🧠 Module 2: Designing Reusable and Robust Prompt Patterns Objective: Learn to craft dynamic, domain-specific prompts and optimize them for reliability and reusability. Topics: Declarative prompt design using JSON/YAML templates Pattern-based chaining: Summarize → Rewrite → Validate → Enrich Prompt versioning & shadow testing Embedding-based contextualization via vector search Tutorial: Template prompt flows with LangChain or custom orchestrators Integrate Pinecone/Weaviate for retrieval-augmented prompting (RAG) Lab: Create a domain-specific RAG pipeline for customer support microservices Prompt telemetry: tracking failures and hallucinations in real-time Case Study: AI-assisted incident summarization in a DevOps platform Assessment: Integration challenge: Add shadow-prompting and compare outputs Functional benchmark: Accuracy delta < 5% vs baseline human response ⚙️ Module 3: API Contracts, Observability, and Security Objective: Ensure API contracts are observable, debuggable, and secure across services using AI. Topics: JSON Schema, OpenAPI, and gRPC contracts for prompt-based services Rate-limiting, token quotas, usage billing Observability with OpenTelemetry (tracing prompt lifecycle) Secret handling, auth tokens, and prompt injection mitigation Tutorial: Wrap your AI prompt service with OpenAPI + Swagger UI Implement tracing spans and correlation IDs with OTEL Lab: Set up alerts for prompt hallucination thresholds Add token budgeting to each user/org-level API request Case Study: Rate-limited generative suggestion system in an e-commerce CMS Assessment: Stress test: Maintain <2% failure rate at 300 concurrent calls Peer-reviewed: Secure API gateway configuration 🚀 Module 4: Multimodal & Multi-Model Prompt Integration Objective: Go beyond text by integrating vision, audio, and multiple LLM providers. Topics: Chaining multimodal inputs (OCR → Prompt → Voice → Action) Routing between models (Claude for analysis, DALL·E for visualization) Prompt arbitration and fallback routing A/B testing across AI API vendors Tutorial: Build a microservice that generates a visual report from text + image input Implement routing logic between Cohere, Mistral, and OpenAI Lab: Compose a workflow: PDF Invoice → Table Extraction → Summary → Audio Message Case Study: AI-powered visual QA system for e-learning platforms Assessment: Multi-model fallback challenge: design with 99.9% uptime SLAs Benchmark: Output quality consistency score > 0.8 🧪 Module 5: Prompt Engineering Ops (PromptOps) Objective: Treat prompts as infrastructure—deployable, testable, observable, and versioned. Topics: PromptOps tooling (PromptLayer, PromptFlow, custom GitOps) Canary rollouts and real-time feedback loops CI/CD for prompts using GitHub Actions and feature flags Managing prompts like code: testing, linting, auditing Tutorial: GitOps-style prompt deployment pipeline with rollback Create a real-time A/B prompt testing dashboard Lab: Roll out a new prompt version using feature flags + evaluation metrics Build a Prompt Performance Heatmap Case Study: Continuous prompt deployment in a real estate chatbot platform Assessment: Prompt coverage report: >90% test coverage Peer-reviewed: Prompt CI/CD pipeline repo 🧠💻 Capstone Project: AI-Augmented Incident Response System Scenario: Build an AI-powered incident triage and reporting microservice suite that: Ingests logs & alerts Summarizes and classifies incidents via LLMs Routes to the correct on-call engineer Notifies via Slack and generates a daily report Requirements: Use at least 2 LLM APIs Implement prompt observability and budgeting Support fallback and retriable operations Expose service via OpenAPI Include Git-based prompt versioning Deliverables: Source code (microservices, prompt flows, dashboards) Documentation and API spec Live demo or screencast Evaluation: Peer-reviewed integration walkthrough Stress test report (>95% successful triage under load) Functional correctness benchmarked against synthetic incidents 🧩 Pedagogical Summary Feature Approach Code-first learning Every concept taught with live-coded examples Live API integrations Integration with OpenAI, Cohere, Anthropic, Pinecone, etc. Deep architectural dives Includes API gateways, service meshes, observability Hands-on labs Practical, guided, real-world development exercises Peer and benchmark assessments Structured reviews + load & quality metrics Capstone challenge Real-world problem, multi-model integration, full lifecycle Let me know if you'd like this as a downloadable PDF or formatted into slides/docs!
