Building Production Agents with LangGraph

Design agents as explicit state machines instead of prompt spaghetti. You will build a typed graph with conditional edges, add checkpointing so runs are replayable, implement retry and refinement loops, and ship an agent that degrades gracefully when a model call fails. Ends with a production deployment that handles concurrency, idempotency and observability.

TypeScript for Large Codebases

Types as design tools. Generics and conditional types, discriminated unions that make invalid states unrepresentable, declaration files, strictness flags introduced incrementally, and monorepo project references that keep builds fast as the codebase grows.

Modern React Patterns and Server Components

React changed shape and a lot of received wisdom expired with it. Server versus client components, the boundaries between them, data fetching and caching, state colocation, and the rendering model that explains why your component ran three times.

Infrastructure as Code with Terraform

Declarative infrastructure that a team can share. State management and locking, module design and composition, workspaces versus directories, importing existing resources, plan review as a code-review artefact, and drift detection in CI.

Streaming Data with Kafka and Flink

Event-time versus processing-time, watermarks, windowing, and what exactly-once actually guarantees. You will build a stateful stream processor with checkpointing, handle out-of-order and late events correctly, and reason about the throughput and latency trade-offs under real partitioning.
