Architecture Lab

How I think about systems.

Reference designs for the kinds of systems I work on, each with its main flow, boundaries, failure handling and trade-offs.

Illustrative reference design built from general engineering practice. It is not the architecture of any employer's or client's production system.

Event-driven microservices with a message broker

Synchronous APIs for requests, a message broker for side effects, and the patterns that keep it reliable: idempotent consumers, retries and dead-letter queues.

  • Microservices
  • RabbitMQ
  • Django
  • REST APIs

Chaos engineering experiment platform

Running controlled failure experiments safely: hypothesis, guardrails, time-boxed fault injection, steady-state checks and automatic rollback.
