CHROME MV3 · IDLE GAMES · LEGAL-TECH AUTOMATION
Everything I have shipped.
Manifest V3 Chrome extensions, browser idle games, and the production legal-tech tooling behind them. Each one designed, built, tested, and shipped solo — most of them free on the Chrome Web Store.
Chrome Extensions & Games
Seven-floor idle conversion tower — biomass to culture, energy, compute, data, stardust, essence. Throughput-clamped generators, an insight tech tree, prestige relics, and six arcade minigames. Fully offline.
Category-based time tracker that never logs your browsing history, paired with a hatch-and-collect playground of 99 critters fed by ordinary page navigation. Fun first, no advice about how to browse.
Local-first Dota 2 companion for the toolbar — an improvement streak measured against your own baseline, goals, hero stats, and private player notes. No account, no API key; data from the public OpenDota API.
Flagship — client-side AI companion for the Chrome side panel: BYO-key chat, hands-free Autopilot episodes, Professor’s Lab, and a hidden Dark Matter economy.
Deep-space idle RPG for the Chrome side panel — 3D starfield camera, orbital physics, ascension. (Chrome Web Store: Sidebar RPG Idle.)
Registry-driven mage idle game — runecrafting, alchemy, pets, curses, slayer contracts.
Dots and Boxes against a dinosaur AI that plays real chain strategy.
A tiny T-Rex that wanders your browser with a full egg-and-hatch collection system.
Fast-food arcade under a timer — combo streaks and a local high-score board.
New-tab extension with 44 collectible characters and hand-written affirmations.
Side-panel collecting game — every page load spawns one of 4,096 procedural critters; snare them across five rarity tiers. Fully offline.
Hatch-and-collect browser game — hatch and raise your brood of Steplings. Pure MV3, fully offline.
Idle wizard bullet-heaven in the side panel — auto-firing spells, build-craft upgrades, evolutions, and prestige runes. Fights while you browse.
God devotion idle set in the Kengir world — rival-god devotion management, job runs, Onslaught combat, Forge crafting, and a branching campaign.
Legal-Tech & Automation
Production tooling built for the process-serving industry on top of ServeManager, the sector’s job-management platform. These aren’t public downloads — they’re internal systems, and tools in this shape are built to order.
Local-first desktop analytics for field-dispatch records — content-hash idempotent ingest, matter-level deduplication, memoized scorecards, and PDF report cards generated offline. Rebuilt as a single file around the question of what actually counts as one job.
ServeManager Expertise
Deep, live-verified work against the ServeManager REST / JSON:API surface — jobs, attempts, notes, invoices, and court cases — including the exact-match job resolution and confirm-gated note-write flow powering the Marshall sidebar. Institutional ServeManager knowledge encoded into reusable schema dictionaries.
Built on ServeManager. Learn more at servemanager.com.
EDMS Court E-Filing
A single-file Playwright robot that drafts Iowa court e-filings (small-claims and civil) against the state’s eFlex/EDMS system, deriving filing type and document set from suit amount. Drafts-only with a PySide6 human confirm-gate — attorneys finalize and pay; the robot never submits.

Court E-Filing Training Environment
A practice environment for a court e-filing system that has no sandbox — every real action is an irreversible submission. One self-contained HTML file, no server and no accounts, so trainees can be wrong cheaply and repeatedly. Correctness is scored at the moment of submission and stored as a flat snapshot, so two assessors reading the same attempt reach the same verdict; results move between machines as an export bundle that imports idempotently.
