BUILDING LLM APPLICATIONS

LLM application development and evaluation

We help engineers with programming experience build an LLM application, covering retrieval, evaluation, safeguards and deployment.

  • The syllabus is the production stack, taught layer by layer
  • Every module is a lab: ship a slice, break it, instrument it
  • Learn while building a real application from your own roadmap
THE SYLLABUS IS THE PRODUCTION STACK

We teach the stack bottom-up, the order in which it actually breaks.

Each layer is a module, each module is hands-on.

By the end, engineers have built each layer and understand how a weakness in one surfaces as a failure in another: poor chunking looks like a hallucination; a missing eval gate looks like a mystery regression weeks later. This is the engineering track of the full [AI Upskilling and Training](/ai-upskilling-and-training) path.

Retrieval (RAG)Chunking strategy, embeddings, hybrid keyword and vector search, reranking, grounding and citation.
EvaluationTest sets, LLM-as-judge, metrics, and CI gates so a change cannot ship a silent quality drop.
Guardrails and safetyPrompt-injection defence, input and output validation, PII handling, refusal and fallback behaviour.
Cost and latencyModel routing, right-sizing, caching, streaming, and token budgeting.
OrchestrationChains, tool calling, state, structured output, and retries for multi-step, tool-using flows.
Deployment and observabilityDeployment patterns, tracing, logging, monitoring, and the feedback loop back into evaluation.

Most teams can wire a model to a chat box.Far fewer can keep one in production.

TOOLS AND HANDS-ON MODULES

Engineers build on the tools they will use in production, on your stack where possible.

Each module is a lab: engineers ship a working slice, break it deliberately, and instrument it.

OrchestrationLangChain and LangGraph for chains, agents, and stateful flows.
Vector storespgvector, Pinecone, or your existing store, with hands-on retrieval tuning.
Evaluation and tracingLangSmith and Langfuse for eval harnesses, tracing, and monitoring.
ModelsWorking across providers and open models, with routing and right-sizing.

Where it fits, the program runs learn-while-building: the cohort develops a real application from your roadmap, so the output is production code your team owns. It pairs naturally with [Scaled GenAI and AI Platforms](/scaled-genai-and-ai-platforms), so trained engineers build on a real platform.

HOW WE RUN IT

Four steps, from level-set to a real application your team runs.

STEP 01

Level-set

Assess the cohort's current skills and pick a build target from your roadmap.

STEP 02

Build the stack

Work through the modules layer by layer, each as a hands-on lab.

STEP 03

Harden

Add evaluation, guardrails, and cost controls, the difference between a demo and a system.

STEP 04

Ship and instrument

Deploy a real application, with observability and a feedback loop your team keeps running.

Experienced engineers ready for fine-tuning, advanced retrieval, and agent design continue into Advanced LLMs. Business teams applying these systems, rather than building them, take AI and GenAI Training.

WHAT GOOD LOOKS LIKE

Assess engineers through a working application.

A tested build.

Complete an application exercise with retrieval or model integration appropriate to the problem.

An evaluation harness.

Demonstrate tests for expected answers and failure cases before accepting a change.

Operational trade-offs.

Explain latency, inference cost, access controls and monitoring choices in the final review.

FREQUENTLY ASKED QUESTIONS

What engineering leads ask us first.

Working software-engineering skills and comfort with an API and a codebase. No prior ML experience is required; we start at LLM application patterns, not model math.

Yes. We adapt labs to your vector store, orchestration framework, cloud, and models so the skills transfer directly to your production environment.

Yes, learn-while-building is our preferred mode. The cohort develops an application from your roadmap, so the output is code your team owns and runs.

TURN ENGINEERS INTO LLM APPLICATION BUILDERS

Design a hands-on cohort mapped to your stack and a real build target.

The syllabus is the production stack, taught layer by layer, so engineers ship a system your team owns and keeps running.
