A practical design for keeping trading strategy logic portable across backtests and live execution by returning plans instead of touching brokers directly.

Building an IoT Device Abstraction Layer in Go

Sun, 02 Nov 2025 00:00:00 +0000

IoT applications get hard to maintain when hardware code and application logic are tangled together. A prototype can read one GPIO pin or one I2C sensor directly. A real system has sensors, actuators, timing loops, message publishing, local storage, APIs, dashboards, and failures that happen at the edge.

The useful boundary is a device abstraction layer: hardware-specific drivers stay below it, application logic stays above it, and the two communicate through small interfaces.
