_{Networks / servers / communications / remote access}

Designed and supported workstations, servers, wireless networks, communications, security controls and remote access. The same work included platform migrations, multi-site support, backup review, service recovery and practical documentation for the people taking ownership.

_{Diagnostics / fabrication / quality / compliance}

Assembled and maintained specialist electronics, diagnosed component faults, sourced parts and fabricated replacements. I also ran product tests and prepared quality, certification and regulatory records. Repair decisions accounted for downtime, parts availability and whether the result could be verified safely.

_{Small computers / media / storage / system services}

Built and recovered small Linux devices expected to run without supervision. Startup, media, storage, connectivity and resource use were treated as one system, including recovery after interruption and proof that a cold start reached the intended operating state.

_{Mixed-format data / offline indexing / private source material}

Built local tools that turn large mixed-format archives into a consistent, searchable view. Normalisation and indexing happen without moving the private source material away from the owner's machine.

_{Web applications / databases / permissions / reporting}

Built systems around contacts, jobs, inventory and reporting, shaped around the process already in use. Delivery covered data design, validation, permissions, imports, exports and clear operating instructions rather than forcing the work into a generic package.

_{Structured exports / charts / filtering / desktop delivery}

Turned XML and CSV exports into searchable desktop reports with charts and filters. The emphasis was on making technical results easier to inspect while keeping a direct route back to the supplied records.

_{Distributed devices / scheduled content / operational support}

Built management software and device integration for groups of remote displays. The work joined content preparation, schedules, device state and operator controls into one manageable workflow, with enough status information to support the devices from elsewhere.

_{Flight systems / payloads / planning / training}

Prepared equipment, coordinated pilots, ran field work, maintained aircraft and trained operators. Product evaluations and proof-of-concept trials brought hardware, sensors and operating procedures together before a documented handover.

_{Photogrammetry / GIS / positioning / spatial processing}

Built workflows for image-based mapping, three-dimensional reconstruction, volumetric analysis, coordinate conversion, control points and field positioning. Utilities prepared shapefiles and other spatial data, checked inputs and reduced avoidable errors before the results reached viewers or reports.

_{TypeScript / WebGL / 3D Tiles / spatial databases}

Developed browser tools for organising and viewing large spatial datasets. The work covered rendering, access control, coordinate handling and layouts that remained practical away from a specialist desktop workstation.

_{Control electronics / sensing / fabrication / testing}

Built and tested prototypes combining electronics, sensors, mechanical parts and custom fabrication. The point was to answer a concrete feasibility question, measure the result and expose weak assumptions before committing to a larger build.

_{Linux / containers / virtualisation / remote operations}

Created operational tooling for Linux services, self-hosted infrastructure and groups of small devices. It covers readiness, maintenance, health and recovery while keeping routine checks repeatable and failures visible.

_{Cross-platform applications / CI / releases / verification}

Built repeatable checking, packaging and release paths for desktop software across operating systems. That includes maintaining patches, producing release artefacts and proving the installed application, not merely the build job that created it.

_{Local tools / coding agents / reviewed changes / evidence}

Worked on locally controlled AI tools and coding-agent workflows, with emphasis on reliable operation, reviewed changes and verifiable results. Automation is useful when its authority is clear and its output can still be inspected by a person.

_{Device workflows / validation / repeatable tests}

Built simulation and configuration tools used to test device workflows without requiring target hardware for every run. These tools make state changes visible, catch invalid inputs early and turn repeated manual checks into reproducible tests.
