Why I Built an Industrial IoT Gateway Using Python and Serverless

Building an industrial IoT platform usually feels like an endless nightmare of fragmented tech stacks. The firmware engineers are writing C++, the backend team is fighting with Docker containers and message queues, and the frontend devs are struggling to render real-time sensor data without crashing the browser. I’ve been there. When I set out to build a scalable remote monitoring system, I knew I had to break this cycle. I needed an architecture that was robust enough for industrial environments, yet agile enough to be maintained by a small team. The solution? Dropping the traditional C/C++ monolithic edge daemons and fully embracing a 100% Python Edge + Serverless Backend + React SPA pipeline. In this series, I will walk you through the exact architecture that allowed me to securely route bi-directional telemetry and commands (D2C/C2D) from local hardware to a modern web dashboard, cutting development time by 80%. Let's dive into the architecture. 1. The Nightmare of "Traditional" Io
