I'm Aodhan. Embedded systems engineer building scientific instruments with FPGAs, custom hardware, and NixOS.
- FPGA — custom Verilog/SystemVerilog for signal processing and precision timing.
- Embedded hardware & firmware — PCB design, bring-up, bare-metal and RTOS.
- Scientific instrumentation — building custom spectroscopy and measurement systems at @solarpi-org.
- Data & monitoring — Python, data pipelines, and dashboards for solar energy systems.
- Nix — declarative infrastructure, dev environments, and deployment from cloud to embedded.
- Test & measurement — oscilloscopes, logic analyzers, ADCs, instrument automation.
