PORTFOLIO & APPLICATIONS / 2026
A collection of released software, developer platforms, commercial client work, and working browser applications. Every project solves a specific workflow problem with verified engineering choices and demonstrable outputs.
A KWin script for KDE Plasma 6 that arranges windows across monitors, with keyboard shortcuts, native settings and a public v1.0.2 release.
The v1.0.2 release documents multi-screen placement fixes and native shortcut settings.
A collaborative developer tool for AI-assisted code review, with terminal and GitHub workflows that organize findings into structured reports.
The artwork is an illustration. Explore the public project to see the software.
A service website for plumbing, heating and cooling, with separate residential and commercial paths, real team photography and direct contact options.
TESSERA / ENGINEERING NOTES / v1.0.2
A release-backed look at one multi-monitor fix. This describes the project’s published evidence, without assigning individual authorship.
On vertically stacked displays, a window snapped near the lower edge of the upper display could land on the screen below.
The release records output affinity by window ID and guards output changes during animation. The intended display survives KWin’s recreation of JavaScript window wrappers.
The v1.0.2 notes report 452 unit tests and 25 matching simulation traces, plus live X11 testing on three displays. These are reported release results, not tests rerun for this website.
The repository keeps Wayland, physical cable hotplug and the side-by-side theme audit as separate unexecuted or deferred live checks. Automated tests do not establish those outcomes.

BUILT TO USE / RELEASED SYSTEMS & APPS
Explore released systems, developer tooling, and working single-purpose browser applications. Every app runs locally with sample data.
Request a projectBrowser apps keep records on this device; exports are portable backups you control. Workspaces start empty, and examples are opt-in. Screenshots use synthetic data; covers show actual working views. No real charges, outbound sending, server accounts or team sync.
Carry a customer from estimate to visit, job checklist, service history and local invoice records.
Accepted scope stays frozen while visits and job checklists keep moving. Invoice and simulated payment records retain their source relationships.
Connect suppliers and purchase orders to partial receiving, SKU stock, local sales and reasoned returns.
Stock comes from saved movements, and recorded orders retain their own snapshots. A basket is preparation, not a stock reservation or a real checkout.
Move from client and proposal revisions to accepted scope, delivery milestones, invoices and manually recorded payments.
Tasks link to actual project milestones. Completing a task changes that task; milestone and project completion remain explicit decisions.
Map incoming columns, review changes against immutable CSV sources and save reproducible recipes, runs and outputs.
Original CSV snapshots stay immutable. Each recipe stage can be inspected before a reproducible run is saved and exported.
Carry manuscripts and owned images through revision-specific review into preserved ready editions and portable documents.
Review notes belong to a particular revision. A preserved ready edition stays readable while a newer draft continues through editing.
Plan recurring sessions, carry owned actions forward, check readiness and preserve numbered minutes with calendar exports.
Decisions and owned actions stay attached to their agenda context. Corrections create a new numbered minutes version instead of rewriting the published record.
Plan work, reuse presets, record timed or manual actuals and review dated actual-versus-plan reports.
Timers retain the rate accepted when they start. Paused intervals stay out of the dated ledger, and later rate changes do not rewrite recorded work.
Plan trips and packing, track equipment checkout and partial returns, and account for maintenance before departure.
Packing counts use actual allocated quantities. A ready version preserves the trip at that point even when equipment details or later plans change.
Connect household RSVPs, seating capacities, vendors and budgets with a dated day plan and portable outputs.
The run sheet groups the existing moments by time of day; it does not invent extra events. Data remains in this browser until exported.
Define resources and locations, receive and move stock, and fulfill real recorded demand with an activity trail.
Configured operations use the actual warehouse example. This remains a single-browser prototype, without a server, shared accounts or live integrations.
Keep a library of editable diagrams, reuse templates and restore checkpoints as new documents before exporting.
Nodes and edges stay editable in the connected example. Browser-local storage and portable exports do not provide collaboration or team sync.
LABORATORY & INTERACTIVE STUDIES
Working prototypes, spatial studies, and graphics sandboxes separate from the primary production software and released applications. Each experiment explores a specific interaction pattern, local data structure, or 3D technique.
Local logistics prototype exploring resource movements, multi-location demand, and deterministic production workflows. Configured with a sample warehouse model; workspaces remain single-browser only.
A local diagram workbench with an editable connected canvas, shape libraries, checkpoints, and portable JSON/PNG export.
Wedding planning journal and run-of-show chronology with guest RSVP tracking, seating capacities, vendor budgets, and JSON backups.
A plain-material Three.js 3D interactive study investigating mechanical packing, component stacking, and case closure.
A navigable graph of deterministic prompts for exploring a topic. This is a local structural tree demo; topic-aware generation is not connected.
Interactive visual explorations: Interface Studio reveals layered CSS component illustration; Open Orbit provides a free-orbit camera study of the 3D workstation scene.
