Field gateway that stops needing a site visit
A Raspberry Pi gateway for remote pump stations that recovers itself from the failures that used to mean a four-hour drive.
R&D Embedded Engineer
Supun Sriyananda
I build safety-critical embedded systems that have to keep working where nobody can reach them.
I work on the parts of a system that have to survive being installed and then ignored — firmware that reboots cleanly at 3am, sensors that keep reporting through a bad link, boards that run a model on a power budget nobody thought was enough.
Most of what I do sits across embedded Linux, edge AI, IoT data pipelines, predictive maintenance and hardware design. I teach as well, and I write up the problems that had no documentation when I hit them.
what i work on
- Embedded Linux
- Yocto and Debian-based images, kernel and device tree work, boot and init on ARM64.
- Edge AI
- Quantising and deploying models to microcontrollers and SBCs with hard power limits.
- Firmware
- ESP32 and STM32 in C and C++, RTOS scheduling, low-power design, OTA update paths.
- Hardware
- Schematic capture, board bring-up, and the instrumentation to prove a fault is real.

I take on consulting work: a system that fails in ways nobody can explain, a board that needs Linux doing something it does not want to do, or a prototype that has to become something you can actually ship. Tell me what is stuck.
