Personal software and research lab
Nagsein
Software, systems, signals, and field notes.
Nagsein is a personal software and research lab by Dean Esterhuizen. It is a place for practical experiments in software engineering, system design, observability, automation, AI-assisted development, and the quiet signals that appear inside complex systems.
Current areas of interest include context tooling for AI workflows, field execution systems, device orchestration, integration layers, and operational software that connects decisions to real-world action.
Software
Practical tooling, integration layers, and maintainable systems for real work.
Systems
Operational patterns, field execution, observability, and control-room workflows.
Signals
Notes from debugging, orchestration, AI workflows, devices, and edge environments.
