CareerOS

My personal career platform, built as a monorepo. Each module is a tool I actually use — a portfolio, an automated job finder, an application tracker, a résumé generator, and a morning-brief agent.

Live → leebrian.dev

Modules

Module	Status	What it is
apps/portfolio	Live	My portfolio — case studies across graphics, engineering, and design
apps/role-grabber	Live	Twice-daily role aggregation from ~110 company boards + curated feeds → ROLES.md; deterministic fit tiers, 🔥 hot / 🆕 new / 🎯 target, term + level
apps/tracker	Live	Application dashboard over the daily data — filter, fit-rank, track stages + follow-ups, two-way Google Sheet sync (durable + cross-device)
apps/resume	V1 live	Résumé-as-code — both variants render to ATS-clean docx/PDF from one data file (content stays private)
apps/apply-helper	V2 live	Answer bank (22 editable answers) + in-app AI drafter — type any question, get a tailored answer via the Claude API (serverless, passphrase-gated), edit, and save to your bank
apps/tailor	Live	Paste a job description → a one-page résumé composed only from my real résumé blocks + a fact-guarded cover letter, as ATS-clean docx/PDF — at leebrian.dev/tailor (passphrase-gated, docx built in the browser) or locally through the apps/resume Word pipeline
apps/secretary	V1	Morning-brief agent — composes what-to-do-today from the feed and emails it daily (Task Scheduler @ 8am)
apps/desktop-pet	V1 scaffold	The secretary's face — a transparent desktop character that pops the brief in a speech bubble (bring your own art)

The job-hunt system

The core loop: grabber finds roles → tracker manages them → apply-helper speeds applications → secretary reminds you daily.

Role-grabber (zero-dependency Node, runs on a GitHub Action twice a day):

• Sources ~110 company ATS boards directly — Greenhouse, Ashby, Lever, SmartRecruiters, Workday, Workable, Recruitee — plus curated aggregator feeds. ~5,000+ live US roles.
• Covers big tech, design-forward companies, game studios (Riot, Epic, Nintendo, Rockstar, Naughty Dog, Scopely…), VFX/animation (Pixar, DreamWorks, Sony Imageworks…), and a large AI-lab set.
• Deterministic fit scoring (title-tier + skills + recency + target + level) → ⭐ strong / ◐ good tiers, no black-box LLM ranking.
• Relevance-gated inbox — filters out unrelated roles (sales/recruiting/finance) while protecting every real tech/design/creative role; categorizes into Graphics·Game, Art·Animation·VFX, Design·UX, SWE, Data·AI·ML, and more.

Tracker (single self-contained HTML, no backend):

• Views: Inbox / Starred / Tracker / Hidden · filters for search, category, level, term (Summer 2027…), sort (newest / best fit / follow-up due), and ⭐ strong-fit / 🔥 hot / 🆕 new / 🎯 target.
• Fit tier on every row · funnel stats (applied / in-progress / offers / this week) · one-click apply → stage tracking → follow-up reminders → notes.
• Two-way Google Sheet sync — your data lives in your own Google Sheet, syncs on every change, and loads on any computer (last-write-wins, never wipes). Plus local auto-backup and CSV export.

The portfolio

Built from scratch on Astro 5 + Tailwind 4, fully static. Two designs ship side by side behind a small switch in the corner:

• Polished (default, /) — the original design with a few things changed. Three intro styles sit behind a switch in the hero (the name in the logo face over the field, a film-credit caption, a spec sheet with the shader's real frame time and GPU). The audience switch (/, /graphics, /engineering, /design) reorders the work in place and updates the URL, so one link can be pasted into a studio application and another into a design one; the résumé link follows. Hovering a company on the holo card swaps the About text for that job's brief without moving the page; clicking opens the full page. Tags are squared outlined labels instead of pills; the grain is gone. Card thumbnails morph into case-study heroes through cross-document View Transitions (no router; unsupported browsers just load the page).
• Original (/classic/) — the earlier version, kept whole for comparison: statement-wall hero, duotone thumbnails, Mona Sans.
• Shared: the shaders (ShaderField, CardShader) use a fract-free permutation lattice hash so they render correctly on Intel MacBooks, where Metal's fast-math fract() used to tear the noise into triangles. scripts/noise-robustness.mjs proves the seam; scripts/shader-smoke.mjs compiles every mode in headless Chrome; scripts/shot.mjs screenshots any page; scripts/copy-lint.mjs keeps boilerplate out of the polished pages; scripts/behaviour-check.mjs exercises the audience switch, the row-filling grid and the About hover in headless Chrome.

Run it

cd apps/portfolio
npm install
npm run dev      # → http://localhost:4321
npm run build    # static output in dist/

Deployed on Vercel; every push to main ships automatically.
