Systems integration, worked through in the open.

A systems-integration and technical-delivery lead working where hardware meets software. I write about the engineering, and I'm building a cyber-physical systems project in the open, about how autonomous systems detect their own faults and fail safely.

What I work on

Where hardware meets software

Systems integration & delivery

The seams between subsystems, teams, and disciplines, where integration risk hides. Requirements framing, interface ownership, readiness, and getting complex programs to a validated state.

Embedded, robotics & automation

Embedded systems, sensing and actuation, ADAS and perception, industrial automation, and the control and coordination problems of embodied systems.

Digital twins & cyber-physical systems

Modelling physical assets, telemetry and edge compute, sim-to-real, and the fidelity problem of keeping a digital model honest to the hardware.

Why integration milestones fail

What actually breaks at the seams between subsystems, and what to check before a milestone.

Validation gaps: “we tested it” is not “it works”

The difference between testing activity and actual evidence of readiness.

Interface ambiguity: the silent killer

Why interfaces go unowned, and the structural reasons no team sees the boundary.

Diagnostic tools & sample work

Async · no call required

Alongside the writing, I keep a small set of diagnostic tools open. No pitch and no funnel: if a milestone is looming and a structured outside read would help, they are here, entirely async. Below is a redacted look at what they produce.

Executive Summary

The system is progressing under compressed timelines with critical interface assumptions undocumented. The primary risk is structural — ownership and validation criteria are implicit.

About Andrew

Athens · Remote & onsite across Europe

Systems Integration & Technical Delivery Lead

I work at the boundary between hardware, software, and delivery, helping technical teams reduce execution risk when complexity outgrows clarity. My focus is the seams: unclear interfaces, fragile handoffs, incomplete validation, and progress that leans too heavily on a few key people.

Over a decade delivering complex hardware-plus-software programs, I work systems-first and artifact-led, turning ambiguous problems into executable plans with clear ownership and defensible readiness.

Currently

Building an open, simulation-first project on how autonomous systems detect their own sensor faults and fail safe: sensor fusion, a digital twin with drift detection, fault detection and isolation, and a safe-state layer. Writing up each milestone. Open to senior systems-integration and robotics / automation roles.
