Médéric Hurier (Fmind), freelance AI Architect specializing in AI agents, MLOps, and security. The website is server-rendered Python: Litestar, strict Jinja, Tailwind CSS v4, DaisyUI v5, and Granian. Small page-specific JavaScript controllers enhance native navigation and forms. There is no client framework, application database, runtime CDN, cookie, or client-side analytics.

The LLM hosting budget tool compares selected open-weight models on GKE with managed APIs. Simple mode starts from a workload, optional daily call count, model, pricing plan, and daily usage window. Teams default to an eight-hour workday with always-on nodes; document jobs and scheduled workflows assume nodes run only inside their active windows. Results lead with the cost decision and rounded budgets, with exact costs, throughput sensitivity, checkpoint trade-offs, and sources in expandable sections. A compact 4B model provides an L4 starting point; Mistral Small 4 defaults to its documented NVFP4 single-G4 setup with a 16,384-token context cap. Advanced settings expose custom token budgets, hardware, performance, and API modes. Capacity checks running hours and active windows separately. All speed assumptions are illustrative; totals include compute and the GKE fee, excluding operations and additional services. See the dated source snapshot for formulas, limits, and provenance.

Development

Requires mise, Docker Engine with Buildx, and network access for initial tool/browser installation and image/scanner downloads. Python and the remaining toolchain are pinned in mise.toml and mise.lock; .mise/locks/ records the browser tools' transitive npm dependencies and must be committed with lock updates.

mise install
mise run install
mise run watch

Open http://localhost:8080; use PORT=8081 mise run watch for another port. .env.example lists runtime variables; .env files are not loaded automatically. The default environment is development; production sets ENVIRONMENT=production. Reload watches src/, content/, and static/; restart after environment/configuration changes.

src/www/app.py constructs the immutable startup snapshot and routes. src/www/__main__.py starts Granian. Templates are wheel package data; the image copies the separate content/ and static/ trees beside the locked environment. AGENTS.md maps module ownership and invariants.

Content and design

src/www/data.py supplies portfolio facts, service availability, HTML, JSON/JSON-LD, vCard, and LLM text. Preserve the owner's voice and factual claims across these surfaces.

The site implements the light-only Fmind DESIGN.md from fmind/theme: white, light gray, charcoal, and blue #174EA6, set in Google Sans. assets/css/input.css owns interface colors; src/www/highlighting.py owns syntax colors. Tests enforce the palette with explicit company-brand exceptions. Tailwind scans src/www/templates/**/*.html.

Fonts are self-hosted Google Sans and Google Sans Code subsets. The font generator pins upstream releases, removes reserved logo ligatures, and preserves timestamps. Public branding masters are /logo.png and /banner.png. Keep private portrait originals outside static/; build:portrait exports /portrait.jpg (longest side 2048px) with orientation/ICC preserved and personal metadata removed.

Share /connect at events; it offers LinkedIn, a vCard, and the full website. /scan is a noindex QR utility. The UTF-8 vCard 3.0 derives public professional details and a sanitized portrait from portfolio data, without a phone number, street address, birthday, or precise coordinates.

Articles in content/articles/ use strict TOML frontmatter. Their validated collection feeds every publication surface, excluding drafts in production. build:images generates responsive WebP derivatives and the SHA-256 provenance lock; check:images never writes. Figures fit the 1280px column; code highlighting is server-side. Follow the article skill.

Decision tools use typed Python formulas, native GET forms, dated sources, and explicit planning limits. Register them in data.py:SITE_PAGES; follow the site skill.

Tasks

mise.toml is the canonical contract used by hooks and CI; mise tasks lists all tasks and aliases.

all runs sequentially and reuses build outputs and its image archive. It requires Docker/Buildx but no cloud credentials. Asset generators, clean, watchers, live scans, and deployment run only on demand; clean deletes generated output.

Lighthouse stays separate: install Chromium, then use mise run test:lighthouse -- --base-url <origin> --mode portfolio for twelve desktop/mobile audits of the portfolio, contact, privacy, archive indexes, and hosting calculator. smoke runs four audits; default full covers the sitemap plus 48 stress audits. Run performance audits without concurrent builds or font generation; keep exact per-page scores.

Cross-browser checks require install:browser:cross and Playwright system libraries, or a matching official browser container via PW_TEST_CONNECT_WS_ENDPOINT. The weekly/manual quality workflow provisions ephemeral runners and retains evidence for 14 days. Run browser suites sequentially because they share local port 8096. Set BROWSER_BASE_URL=https://www.fmind.dev for production journeys; local servers otherwise start and stop automatically.

Dispatch that workflow with gh workflow run quality.yml -f target=production after verifying the deployed commit to run Chromium, Firefox, WebKit, and the same strict Lighthouse matrix against the public site on clean runners. The default local target qualifies the checkout; production mode does not deploy or change the service. Use runner evidence when other workstation workloads distort performance measurements, preserving failed reports and score thresholds.

Deployment

Cloud Run serves https://www.fmind.dev/ in project www-fmind-dev, region europe-west1. infra/ owns service settings, registry, keyless identities, alerts, and analytics. Keep minimum instances at 0 at both service and revision levels, maximum 5, and request-based CPU. The qualified runtime uses 1 CPU, 512 MiB, concurrency 32, a 30-second request timeout, and twelve startup attempts five seconds apart. Startup builds article Markdown once for HTTP, LLM text, and MCP. Maximum instances limits scaling; it is not a hard billing cap.

A main push runs the full gate, builds a non-root image with SBOM/provenance, pushes it, and scans and smoke-tests its immutable digest. It then creates a no-traffic revision under the candidate tag; test:candidate requires that revision to match IMAGE_REF/GITHUB_SHA and to serve health, profile, and the MCP server card on its tagged run.app URL. Only then does CI route 100% of traffic to that exact revision; a failed candidate leaves traffic on the previous revision. test:deployed finally verifies that the ready revision receiving 100% of traffic matches IMAGE_REF and GITHUB_SHA, preserves scale-to-zero checks, and probes public health/profile/MCP discovery. CI never rolls back automatically: if this post-promotion check fails, traffic stays on the new revision until the owner redeploys the preceding qualified digest with the manual rollout below. Error-log review remains an independent release check because the deployer has no log-reading role. Actions are SHA-pinned and Dependabot maintains ecosystem updates.

Workload Identity Federation binds each CI identity to one workflow file on main (see SECURITY.md). OpenTofu ignores the image and keeps CI-managed traffic; CI never applies infrastructure. Because traffic is pinned to verified revisions, an applied service-template change serves only after the next deployment promotes it.

Infrastructure changes require a reviewed saved plan and owner-authorized apply through the infra skill. Remote state is gs://www-fmind-dev-tfstate/infra/state; its bootstrap bucket is managed separately and requires versioning and enforced public-access prevention. Reconcile service changes before deploying the application.

For manual rollout/rollback, mise run deploy europe-west1-docker.pkg.dev/www-fmind-dev/app/www-fmind-dev@sha256:<64-lowercase-hex> <40-lowercase-hex-commit> accepts one qualified repository digest and the commit it was built from. It creates a uniquely named no-traffic revision under manual-candidate, verifies its digest, commit, capacity policy, and tagged health/discovery, then routes traffic to that exact revision. A failed or replaced candidate leaves serving traffic unchanged. Tags, foreign repositories, short or uppercase SHAs, and extra flags fail before gcloud. First run check:image:digest <digest-ref> and test:image <digest-ref> for a new digest. Then run IMAGE_REF=<digest-ref> GITHUB_SHA=<commit-sha> mise run test:deployed and check browser journeys and error logs. Keep the preceding qualified digest for rollback. Semver publication follows the release skill.

SECURITY.md owns vulnerability reporting and residual advisory review. Deployment blocks fixable HIGH/CRITICAL vulnerabilities and secrets; scheduled scanning retains unfixed findings with a separate read-only identity that only security.yml on main can assume. GitHub dependency alerts, security updates, secret scanning, and push protection are enabled; main rejects deletion and force pushes.

Analytics and privacy

/privacy describes the data flow. HTML GET responses emit aggregate path/status, referrer hostname, validated UTM tokens, and a heuristic bot flag. Redirects are excluded; geography remains empty. BigQuery partitions expire after 180 days without duplicate Cloud Logging retention. Analytics omit IPs, raw user agents, full referrers, cookies, sessions, and trace identifiers. Separate private Cloud Run operational logs may contain IPs, user agents, and full URLs and expire after 30 days.

Use the website-analytics skill or uv run --locked python -m scripts.website_analytics for a bounded, no-charge report. Reports fail on incomplete/changing data and are not unique-visitor or conversion measurements. Keep production reports out of Git.

Tracing is opt-in through standard OTEL_EXPORTER_OTLP_* variables. Operational logs correlate trace/span IDs; analytics omit them.

Use finops-analytics for cloud cost, budget, and optimization reviews. OpenTofu manages the billing APIs and private EU dataset billing_export. Activate Standard usage cost in Cloud Console → Billing → Billing export, selecting project www-fmind-dev and this dataset; leave other export types disabled. The account-wide export needs project-filtered, on-demand queries with dry runs and a 100 MiB scan cap. Verify activation and table arrival before claiming costs are available; initial backfill can take five days.

Agent access

The public /agents guide is the integration reference. Connect an MCP client to https://www.fmind.dev/mcp for read-only, unauthenticated portfolio, publication, search, service, and hosting-comparison tools. Browser requests have same-origin protection; request bodies are bounded. MCP uses finite JSON responses to POST requests. GET/HEAD return 405 with Allow: POST; this service does not offer notification streams or subscriptions. Tools never provision, run LLMs, book services, or send messages.

/api/profile and its JSON Schema share the startup snapshot with LLM text, feeds, sitemap, and JSON-LD. Homepage/article routes support Accept: text/markdown and Vary: Accept; HTML wins ties. Fixed article .md URLs remain available. Readers that reject text/markdown can read the regular article URL as server-rendered HTML without JavaScript. Prefer search followed by individual article reads; /llms-full.txt is a bulk export for readers that need and can handle the whole collection. The API catalog, MCP server card, and packaged visitor skill expose discovery; use server/discover for protocol negotiation. Visitor skills are separate from repository maintenance skills.

Keep identity, Luxembourg work location, and service availability in src/www/data.py. The homepage, profile JSON/MCP, and LLM summaries share these facts. Article HTML and Markdown identify the author; /llms-full.txt retains each article's dates and canonical link. Validate search appearance with the local Lighthouse task; indexing and ranking require separate Search Console evidence after deployment.

server.json tracks the website release for io.github.fmind/portfolio. MCP Registry publication is a separate owner action after live verification: mcp-publisher validate server.json, mcp-publisher login github, then mcp-publisher publish. Verify the latest entry through the Registry API. Discovery does not guarantee client adoption or AI citations.
