Go

OttO is a Go-based IoT edge gateway that connects sensor stations, MQTT messages, REST APIs, WebSocket dashboards, and application logic at the boundary between devices and backend systems.

Sugo Music dashboard work managing the software process and building Go backend services for a React artist dashboard.

Why floating-point numbers are wrong for prices and money, and how fixed-point integer types in Go eliminate rounding errors in financial calculations.

How to design a strategy interface that runs identically in simulation and live trading — separating business logic from execution so strategies can be developed, tested, and deployed without modification.

How Go interfaces, generics, mocks, and a device manager separate hardware drivers from IoT application logic in an edge runtime.

How the OttO IoT gateway exposes sensor state through a Go REST API, why HTTP is the application boundary for dashboards and tools, and what to avoid when turning internal device data into public responses.

How the OttO IoT gateway uses MQTT to receive telemetry from device stations, parse topic-based sensor identifiers, pass readings through Go channels, and protect the gateway from unbounded in-memory growth.

Configurations are part of most every program, configurations can be handled in a number of different ways. This is my simple method for handing configurations variables in Go. Check it out!
