How building a portable escape room made me a better microservices developer
summary
Built a portable IoT escape room with maglocks, servos, MPU6050 spirit‑level sensors, a musical‑tone keypad and a five‑box Simon‑Says rig, using ESP32/ESP8266 devices talking to MQTT (Mosquitto) + RabbitMQ bridge. Game targets a 45–60 minute finish time and adapts difficulty with an escape‑room‑run state machine (process‑manager/saga). Monitoring uses MQTT queue length, processing time and critical time; workarounds include a messaging bridge for delayed delivery, time‑to‑be‑received semantics and richer queuing for reliable orchestration.
